The United States of America.

The United States of America is the fourth largest country in the world after Russia, Canada and China. It occupies the central part of the North American continent.

The United States of America is a federal republic, consisting of 50 states.

The country is washed by 3 oceans: the Arctic, the Atlantic and the Pacific. The country has many lakes. There are also many rivers on the US territory. The longest of them are the Mississippi, the Missouri , the Columbia, the Rio Grande and some other. On the US territory there are mountains and lowlands.

The climate conditions are rather different. The country is rich in natural and mineral resources: oil, gas, iron ore, coal and various metals.

The USA is a highly developed industrial and agricultural country. The main industrial branches are aircraft, rocket, automobile, electronics, radio engineering.

Americans are made up from nearly all nations and races. The country population is over 250 million. The national symbol of the USA is its national flag “Stars and Stripes”, having 50 white stars and 13 white and red stripes on its field, symbolizing the number of the original states.

The United States of America is federal state, headed by the President. According to the US Constitution the powers of the Government are divided in to 3 branches1: Legislative2, Executive3 and Judicial4.

The Legislative power belongs to the Congress, consisting of the Senate and the House of Representatives. The Senate represents the states while the House of the Representatives5 – the population. The Executive power belong to the President and his Administration (Vice-President and Cabinet of Ministers). The Judicial power belongs to the Supreme Court and the system of Federal, State and District courts.

There are several political parties in the USA, the largest of them are the Republican (symbolized by a donkey) and the Democratic (symbolized by an elephant).

New York is a city where all the languages of the world are spoken and where people live on the ground, travel under the ground and work in the sky.

New York makes a great impression on all visitors because of its many high buildings, its theatres, museums and hotels, its beautiful bridges, and its expensive shops with their fabulous (баснословный) prices.The first permanent white settlers (поселенцы) came to New York from Holland in 1626. These Dutch settlers bought all of Manhattan Island (остров) from the Indians for the equivalent of twenty-five dollars, while today some of this land costs a million dollars an acre. This island is the heart of the city.

It is on Manhattan Island where most of the skyscrapers are located. This island is connected by six long bridges, as well as by tunnels and ferries (паром), with the other four districts that constitute New York City.

New York is the largest city in the United States. Today there are more people living in the New York City than in Australia, Peru or Sweden.

For transportation New York depends (зависеть) mainly on buses, the subway, taxis and ferries. The buses are slow because of the crowded streets, whereas the subway train can go as fast as railroad trains, sometimes stopping only at the most important stations. We may go all day by the subway for the same rare, if we only change trains but do not go out of the stations.

New York moves vertically as well as horizontally, taking its people by elevator to their offices on the fortieth, sixtieth, and eightieth floor.

New York is the richest and the poorest, the most modem and the most old-fashioned (старомодный) of cities, with expensive hotels and cheap boarding houses, the home of symphonies and popular jazz clubs, cathedrals (собор) and night clubs; the home of the famous Metropolitan Opera and the Metropolitan Museum of Art; the home of most of the largest publishing houses (издательство) of the United States and the biggest newspapers. On the Fifth Avenue there are many expensive stores of international fame, but around the comer one may find little shops where imitation diamonds and cheap souvenirs are sold.

Agriculture provides people with food, feed and other useful products. All over the world farmers cultivate valuable plants and raise productive domesticated animals. There are two main branches in modern agriculture: crop production (or crop farming) and animal husbandry (or animal farming).

Nowadays, in many countries people are still relying on meat, milk and eggs as main sources of food. Both breeders and farmers have already bred and are still breeding highly productive agricultural animals. Animal farming is a process in which a farmer breeds, raises and cares for livestock either for commerce or private use.

The word "livestock" refers to domesticated animals such as beef and dairy cattle, sheep, goats, swine (hogs), horses, donkeys and mules, buffalo, oxen, rabbits or "exotic" animals, for example, camels, emus, ostriches, or any animal which a farmer keeps and uses either for food or pleasure. Sometimes animal scientists include in this term also poultry, such as chickens, ducks, geese and turkeys, but they include neither honey bees nor fish within the term "livestock". However, poultry farming and beekeeping are important branches of agriculture as well as aquaculture1.

There are over a hundred large land mammals in the world but man has domesticated only few types into livestock. There are two main requirements for domestication of mammals: 1) the availability of feed which a farmer can easily control and provide; 2) a rapid rate of reproduction. As cattle, sheep and horses are herbivorous mammals, farmers try to keep these domestic animals on pastures. However, farmers often grow either cereals or other agricultural crops as additional feed for their animals. Such ruminant animals as cattle, sheep and goats are important for people because they convert large quantities of grasses or other types of feeds, as well as non-protein nitrogen into meat, milk and wool. Poultry also convert feed efficiently into protein.

Historically, livestock and poultry have provided the following benefits to humanity: meat, eggs, dairy products, raw materials, fertiliser, labour, management of land.

1) Meat and eggs. In many countries livestock replaced wild game as the main source of animal protein because only livestock convert various food sources into human food. Poultry provide people with white meat as well as with eggs.

2) Dairy products. People process milk of cows, sheep, goats into a variety of valuable dairy products such as yoghurt, cheese, butter, ice cream, kefir, and koumiss.

3) Raw materials. Livestock produce useful raw materials, for example, horses and cows provide leather, poultry produce feather and down, sheep and goats provide wool for textile industry.

4) Fertiliser. Livestock leave behind manure which farmers spread on fields and this increases yields of crops many times. Historically, plant and animal farming have been closely linked.

5) Labour. In modern agriculture neither cattle nor horses are the main source of mechanical energy. However, in some poor countries people are still using livestock as draft cattle.

6) Management of land. Sometimes farmers use the grazing of livestock as a way to control weeds.

When a farmer is planning to rear livestock, he usually chooses the most suitable type for the local conditions. Both climate and type of land, as well as local traditions influence a farmer's choice.

Animal scientists help farmers to develop and improve agricultural industry. Different animal sciences are important for specialists who work in the field of animal farming such as: animal physiology, nutrition, breeding and genetics, ecology and ethology, livestock and poultry management.

Students of animal science are interested in processes how agricultural animals convert feeds into food and other useful things which people need. They conduct research in different fields of animal husbandry and try to improve production, yield and growth of various animals. Thus, they mainly specialise in such disciplines as nutrition, genetics and breeding, or reproductive physiology. There are special courses to train veterinary scientists who study diseases of farm animals, methods of vaccination and animal treatment.

Graduates of the faculty of animal husbandry work in veterinary and human pharmaceutical industries, in industries which provide farms with livestock and feeds as well as in educational institutes. They can work both for private research firms and federal or state experimental stations.

An animal breeder is one of the oldest world professions. Historically, there are certain sub-professions within the field of animal husbandry. They have specific names according to the animal for which a person cares, for example, a cattle breeder (or a cattleman), a pig breeder (a hogman), a sheep breeder (a sheepman), a horse breeder (a horseman), a poultry breeder (a poultryman), a beekeeper or an apiarist, a dog breeder or a cynologist.

Today, managers of commercial farms organize the work of many different specialists who raise thousands of various animals. Farms and ranches employ breeders, veterinary surgeons (or vets), feeders and milkmen who help to care for the animals. Nowadays farmers use modern techniques and achievements of different natural sciences because this helps to improve the ability of animals to convert feed into meat, milk, or fibre more efficiently and improve the quality of the final products.

The word "physiology" originated from the Greek language and it consists of two parts: physis which means "nature" and logos which is "word". In general, physiology is the study of mechanical, physical, and biochemical functions of living organisms. Physiology has traditionally been divided into plant physiology, animal physiology and human physiology but the physiology principles are universal, even if a particular organism is being studied.

Animal physiology is the study of animal functions that is the study of "how animals work". The rapid development of animal physiology as a distinct discipline began in the 19th century and was stimulated by the requirements of animal husbandry and veterinary science. Animal physiology is subdivided into the four main parts, such as general physiology, special physiology, comparative physiology and age physiology. General physiology deals with the analysis of such universal and important processes as blood circulation, metabolism, respirations etc. Special physiology applies general physiological principles in order to investigate characteristics of a particular animal species. Comparative physiology concentrates on similarities and differences of physiological functions of various living organisms. The problems of how physiological functions change with animal age are of special interest to age physiology.

The main approach in animal physiology is to study the evolutionary origins of the physiological mechanisms in order to understand the significance of these mechanisms for modern-day animals. Modern physiology which is based on chemical, physical and anatomical methods investigates biological organisation of the animal body at different levels, that is, cells, tissues, organs.

One of the parts of special physiology is devoted to farm animal physiology. The aim of this science is not only to study physiological functions of the farm animal body, but to control them in order to increase the production of eggs, offspring, milk, meat and wool. The problem of how to maintain good health of farm animals throughout a long lifetime of high production is of great importance to farm specialists as well.

Farm animal physiology is closely related to veterinary science as it is necessary to know physiological standards and the physiological reactions which take place in the body of a healthy animal in order to cure sick animals and prevent different animal diseases. The problems of sterility and nutritional disorders are studied by physiologists as well as by veterinary surgeons.

Animal requirements in nutrients and energy depend on their physiological features, so feeding rations are calculated on the basis of physiological data. The feeding systems for rearing young animals are being developed on physiological parameters as well. Physiological characteristics such as age and weight are considered by the scientists when animals are fed with vitamins, antibiotics, microelements or hormones.

Farmers should take into account some important physiological features of animals in different situations, for instance, when a farmer is going to use artificial insemination9 or train sport horses or dogs. Physiological parameters of farm animals are of special value to engineers who design different farm mechanisms, such as milking or feeding machines.

Other major branches of scientific study that have grown out of physiology research include biochemistry, biophysics, biomechanics, pharmacology, cytology as well as genetics which are known as the biological bases for rational animal husbandry.

The aim of farm animals breeding is to improve qualities which are considered desirable by humans. Long before the scientific principles to the selection of superior animals were developed and the planning of mating combinations was introduced in practice, all species of farm animals were subjected to selective breeding to some extent. At present, in order to modify livestock and poultry and control propagation of domestic animals, breeding procedures involve the application of several basic sciences, mainly reproductive physiology, genetics and statistics.

Animals are bred for utility, sport, pleasure, and research. The purposes of animal breeding vary with regard to species, local conditions, and time. For instance, early in history horses were bred mainly for riding and as draft animals; and nowadays, to a large extent, horses are being bred for sport (racing and hunting). As to poultry, in the past chickens bred for the combined production of eggs and meat, but nowadays most European countries farmers mainly specialise in such breeds and crosses which produce either eggs or meat.

At present, farmers are using special breeding programmes in order to maintain herds and flocks of higher genetic merit. These programmes include such steps as: 1) the estimation of the breeding value of animals; 2) thorough selection of animals for breeding; 3) the application of one of the mating systems.

The problem how to estimate the breeding value of animals has been researched thoroughly by scientists for different kinds of animals. On the one hand, it is necessary to select animals for breeding on the basis of objective measurements of traits that are decisive for the production. On the other hand, it is often impossible to judge animals' productivity only on the basis of their appearance, so farmers started systematic recordings of such individual animal characteristics as milk yields, growth rate and muscle development for bulls etc. Progeny testing and performance testing have been introduced to judge young males (bulls, rams, and boars) that will be used for breeding. Actual measurement of an individual animal's performance is a rather recent innovation in animal breeding and it has established the foundation of breeding programmes.

Nowadays it is known that the breeding value of an animal depends on the genes which it passes on to its offspring, so genetics has become the basis of animal selection and breeding. It has been found that some traits (coat colour, blood type etc) are inherited in accordance with the laws of heredity, while other traits (wool yield, egg production etc) are subjected to variations and are greatly influenced by the environmental factors.

Selection is based on the breeding value of animals and can be carried out in different ways such as mass selection, pedigree selection, family selection, and progeny selection. There are certain advantages and disadvantages of these systems, thus selection is usually made in a number of steps. With regard to dairy, bulls selection on the basis of pedigree is made soon after birth; a second selection is made later and based on growth rate during the first year of life and fertility in the first series of inseminations; and, finally, a third selection depends on the results of progeny tests, when offspring are old enough and may be judged.

Animal breeders apply different mating systems such as inbreeding, outbreeding, linebreeding, crossbreeding as well. The purpose of any method of breeding is to exclude undesirable traits and combine the most essential characteristics in a new animal breed. Along with various breeding methods, the introduction of such techniques as artificial insemination, transplantation of embryo from donor females of high merit has become of great use in breeding all species of farm animals.

To sum up, scientists apply the same basic principles of breeding to any animal species, though the practical approach to the problem may differ to a certain extent and it depends on the rate of animal reproduc­tion, selection method, mating system, as well as on some genetic and environmental factors.

Since animal nutrition research began to develop rapidly during the 1930s, many discoveries about animal metabolism and nutrient requirements have been made. Nutrition is interpreted as the study of organic process by which an organism assimilates and uses food and liquids for normal functioning. Adequate nutrition for any living organism is necessary for the following reasons: 1) in order to provide adequate energy levels; 2) to maintain proper body structures and processes, for instance, muscle function, immune protection, bone density and strength; 3) to ensure the repair and development of all organism's systems, thus to maintain balance between health and disease. In the case of farm animals, proper nutrition is affected by various factors, such as animal species and breed, animal age, body shape and size and other physiological characteristics. The lack of or deficiency in any nutrient may cause animal weakness and even illness.

A nutrient is any element or compound which is necessary for an organism's metabolism, growth, development or other functions. It is essential to provide farm animals with adequate amounts of nutrients which they get from various feeds. In general, animals require the same nutrients as humans. There are six basic nutrients which are important animals' health and they are classified into the two main groups: substances that provide energy; 2) substances that support metabolism, former group includes carbohydrates, proteins and fats, the latter comprises minerals (for instance, phosphorus, calcium), vitamins and water.

It has been found that any particular substance can play more than role in the body. For example, most animals get energy from carbohydrates and fats, which are oxidised in the body. However, protein supplies energy if other sources are inadequate or if it is supplied in great excess above the requirements of the body. Moreover, proteins provide the building blocks (amino acids) for enzymes and other proteins within the body. Thus, for most living organisms nutrients provide not only the energy necessary for certain vital processes but also the various materials from which all structural and functional components can be made up.

On the one hand, there are so-called non-essential nutrients which are synthesised by the cell if they are unavailable to the living organism with the food or feed. On the other hand, there are essential nutrients which cannot be manufactured within the cell in the body. Consequently, it is important to supply farm animals with feeds which contain certain essential amino acids as well as essential fatty acids.

The problem of proper feed supply is of great importance to animal husbandry. Thus, various animal feeds are grown or developed for livestock and poultry, selected and prepared in order to provide highly nutritional diets that both maintain the health of the animals and increase the quality of such farm products as meat, milk, or eggs.

Scientists have studied the usefulness of different feeds as sources of essential amino acids, vitamins, and minerals, as well as lipids and carbohydrates. They also have suggested the proper balance of available nutrients in the animal diet and as a result different nutrient supplements and feed-processing technologies have been developed. Since the 1950s, antibiotics and other growth stimulants have been added to feeding rations in order to increase the rate of growth and reduce death loss of farm animals. Antibiotics help to overcome the growth-depressing effects of an inadequate and poor-quality diet or of imperfect management practices, but their effectiveness differs among animal species.

The achievements of animal physiology and special studies of life processes in farm animals have ensured the development of the optimal diet for each animal. Many of the feeds have appeared as the result of research, experimentation, and chemical analyses which were conducted by animal scientists. However, the problem of adequate animal nutrition is still the subject of current studies for farm scientists. Human nutrition has been improved as a result of animal nutrition investigations.

The word ecology originates from the Greek language and means "the study of the place to live". In general, ecology as a branch of biology deals with the relationships between living organisms and their environment. Animal ecology began to develop rapidly as an applied area of ecology only in the middle of the 20th century. Animal ecology concerns the study of population dynamics, distribution, behaviour, and the interrelations of animals and their environment. In the beginning, animal ecology developed separately from plant physiology. However, animals depend upon plants for food and shelter, so it is impossible to understand animal ecology without plant ecology. This is particularly true in such applied areas of ecology as farm animal ecology as well as ecology of wildlife. Modern ecology considers interrelationship of both plant and animal communities as a whole biotic unit.

Ecology is mainly based on the ecosystem concept which is applied to units of various sizes such as a pond, a field, a pasture, a forest or a large ecoregion. When an ecologist is going to analyse any ecosystem, he will study the living organisms which inhabit this specific area, the physical environment, and all interrelations in this particular unit of space. The term "environment" includes both physical surroundings and biotic communities. The former means a large variety of local abiotic (nonliving) factors like temperature, sunlight, minerals, soil, and water. Different plants and other organisms that share the organism habitat are known as biotic communities. In farm animal ecology, the emphasis is put on farm animal relationships to human society and the whole economy within a particular ecosystem. For example, before a large commercial hog breeding farm is built, ecologists will study such problems as the pollution of the soil and water resources by the animal wastes, the influence of grazing on the ecology of the nearest pastures etc. Thus, a farm will not be built until the problems of water recycling and utilisation of animal wastes are considered and solved.

Within the ecosystem, species are connected and they depend upon one another in the food chain, and exchange energy and matter between themselves and with their environment. The concepts of the food chain and ecological niche were described in the theses by Charles Sutherland Elton (1900-1991), a British biologist and naturalist. The following food chain "the grass (or other plants) → the herbivore (cattle, sheep) → the man" is of great interest to farm animal ecology.

Human interference in the development of ecosystems is widely spread. Farming is the deliberate maintenance of such an ecosystem which is highly productive but relatively unstable. Consequently, the proper management of ecosystems for optimal food production as well as thorough study and analysis of various natural cycles (such as a water cycle or a nitrogen cycle) are of great importance to ecologists.

Farmers have widely adopted intensive systems of crop and animal production which provide bases for reliable food production. However, there are some advantages and disadvantages of intensive farming. On the one hand, if farmers apply modern cultivation practices and fertilisation in order to increase the soil fertility, yields of forage crops will be higher and farm animals will be provided with enough amounts of feed. Farmers widely use intensive methods for producing animal products which include confinement of poultry in small cages, swine in small pens, and sheep and cattle in small lots. Thus, the study of the relationships between farm animals and their surroundings such as temperature, air and light conditions is of special importance to ecologists. It has been found that proper lighting management may increase both poultry and livestock production, so lightening is controlled on any type of farm now. Furthermore, it has been shown that confinement leads to savings in labour, feed, and other production costs. Besides, when animals are kept in individual pens, it will be easier to ensure proper disease control. So, the introduction of new methods of intensive farming has enabled farmers to satisfy the needs of popula­tion in animal food product.

On the other hand, in the long run, such intensive systems of farming may cause serious ecological problems and even ecological crises. It has been shown that cultivation and fertilisation result in a disbalance of nutrients, an increase in pollutants, in pesticides accumulation in the soil, or an increase in susceptibility to plant diseases. Moreover, confinement of farm animals has come under attack as cruel to the animals, and protective legislation of animal right has been advocated.

Nevertheless, livestock and poultry farmers claim that if the animals are under any stressful conditions, they will show sharp decreases in productivity, but milk yields and egg production are maintained at high levels on commercial farms. Since the 1970s, the behavioural adaptation of animals to their surroundings and the effects of environmental stress on the immune status of livestock and poultry have been studied thoroughly by ecologists.

At present, ecology is a multi-disciplinary science which involves plant and animal biology, physiology, genetics, behaviour, meteorology, geology, sociology etc. It is often difficult to draw a sharp line between ecology and any of these sciences. The knowledge of ecology provides the necessary basis for proper management and conservation of natural resources as well as for maintenance of essential ecological processes and ecosystems.

Ecology is widely studied as one of the most important aspects of biology as it has become clear that such problems as the increase in population, food scarcity, environmental pollution, and some sociological and political problems are to a great degree ecological.

VeterinaryScience is also called veterinary medicine and includes the prevention,diagnosis, and treatment of the diseases of domestic animals and themanagement of other animal disorders. The field also deals with those diseases that are intercommunicable between animals and humans.

Persons who serve as doctors to animals have existed since early times, andveterinary practice was already established as a specialty as early as2000 BC in Babylonia and Egypt and the ancient Greeks had "horse-doctors". The first veterinary schools in Europe were established in the mid-18th century and since that time veterinary science has rapidly developed alongside with modern medicine.

Animal health is to ensure the efficient production of wholesome animal products. Farm animals are susceptible to various infectious diseases andmay suffer from viruses and harmful bacteria, so animals should be examined by veterinary surgeons regularly in order to notice disease symptoms in time and take the necessary preventive and control measures.Such common animal diseases as mastitis, brucellosis, swine fever,erysipelas, anthrax, and leptospirosis can quickly spread and cause major losses among stock animals, so they must be controlled or preventedby veterinary surgeons.

Vaccination and immunisation, sanitary measures, and the severe segregation,or quarantine, of sick animals should be used by farmers and veterinary surgeons to prevent the spread of infectious diseases such as anthrax,bovine tuberculosis, brucellosis, canine distemper, and rabies.Sanitary control of animal housing and proper pasture management are to eliminate any carriers of animal infectious diseases which can be easily transmitted by water and soil.

The governmentalofficials must be informed about the outbreak of a notifiabledisease in order to prevent the disease spread. If an animal has contact the infectious disease and cannot be cured, it will have to be slaughtered.

Veterinary surgeons also treat parasitical infections, unsanitary conditions which may cause lower fertility in livestock, and nutritional disorders, and they often have to set broken limbs and neuter domestic pets. Besides, veterinary scientists investigate the chronic infectious diseases associated with high morbidity rates and various metabolic disorders. The development of vaccine to control Marek's disease in chickens is an example of the economic effect of animal-disease research that was conducted by veterinary scientists.

A veterinary surgeon's training must include the study of the basic preclinical disciplines of anatomy, histology, physiology, pharmacology, microbiology as well as bacteriology, virology, parasitology, and pathology. The clinical subjects of study may be divided into internal medicine, preventive medicine, surgery and clinical practice.

Internal medicine includes the diagnosis and treatment of diseases as they affect animals. Preventive medicine should consider the aspects of disease prevention and control, especially such diseases that can be transmitted between animals and humans or diseases that may influence human health. Generally, several preventive techniques are available for the use in the prevention of disease in an animal population such as quarantine, immunisation, environmental control, various methods of disease control and eradication, early diagnosis of a disease. It has been proved that animal diseases may be prevented to a great extent by ensuring proper hygienic and sanitary conditions on a farm, which include the maintenance of safe water supplies, air sanitation, pest control, the improvement of animal housing etc. Surgery includes wound treatment, fracture repair, the excision of body parts, and the use of such techniques as radiology, anesthesiology, obstetrics, treatment of lameness etc. In most veterinary schools, clinical practice enables students, especially future veterinary surgeons, to observe and assist with actual cases of disease or other conditions which require attention. In both medical and surgical treatment, the same techniques are to be used as in medical practice on humans.

In most countries of the world, professional veterinary surgeons must complete a special educational programme. According to this programme students are to study for four or six years at the university and only after such a course of study the degree of doctor of veterinary medicine is to be awarded. Moreover, in many countries veterinary surgeons must obtain a licence to start their practice from some duly constituted authority". Veterinary surgeons may specialize either in the care of small animals such as pets and work in banian hospitals, while others may treat mainly livestock. A few veterinary surgeons may be employed by zoos or circuses to examine and take care of wild animals.

Agriculture is the production of food and goods1 through farming. Agriculture was the key development that led to the rise of human civilization, with the husbandry of domesticated animals2 and plants (i.e. crops) creating food surpluses that enabled the development of more densely populated3 societies. The study of agriculture is known as agricultural science.

Agriculture encompasses a wide variety of specialties and techniques, including ways to expand the lands suitable for plant raising, by digging water-channels and other forms of irrigation. Cultivation of crops on arable land4 and the pastoral herding of livestock on rangeland remain at the foundation of agriculture. In the past century there has been increasing concern to identify and quantify various forms of agriculture. In the developed world the range usually extends between sustainable agriculture (e.g. organic agriculture) and intensive farming (e.g. industrial agriculture).

Modern agronomy, plant breeding, pesticides and fertilizers, and technological improvements have sharply increased yields from cultivation, and at the same time have caused widespread ecological damage and negative human health effects. Selective breeding5 and modern practices in animal husbandry such as intensive pig farming6 (and similar practices applied to the chicken) have similarly increased the output of meat, but have raised concerns about animal cruelty and the health effects of the antibiotics, growth hormones, and other chemicals commonly used in industrial meat production.

The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. In the 2000s, plants have been used to grow biofuels, biopharmaceuticals, bioplastics7, and pharmaceuticals. Specific foods include cereals, vegetables, fruits, and meat. Fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo. Other useful materials are produced by plants, such as resins. Biofuels include methane from biomass, ethanol, and biodiesel. Cut flowers, nursery plants, tropical fish and birds for the pet trade are some of the ornamental products.

In 2007, about one third of the world's workers were employed in agriculture. The services sector has overtaken agriculture as the economic sector employing the most people world wide. Despite the size of its workforce, agricultural production accounts for less than five percent of the gross world product 8(an aggregate of all gross domestic products9).
