POLLUTION - NO EASY ANSWERS

It's not hard to find examples of pollution in our society. But it is hard to define exactly what pollution is. For example, is a can tossed on the ground pollution? How about an unsightly billboard? The noise from a nearby airport?

According to experts, all of these examples can be types of pollution. Broadly defined, pollution is any human-caused change in the environment that creates an undesirable effect on living and nonliving things. Most types of pollution cause some type of physical harm. But some don't. Noise, for example, often creates more psychological damage than physical damage, but it's still considered a type of pollution. In short, pollution is bad stuff—for the environment and for people and other living things.

From Manure to Monoxide: As long as people lived in scattered settlements and the world's human population was relatively small, pollution wasn't much of a problem. But once people began to live in cities and to invent machines and synthetic chemicals, pollution started taking its toll. Pollution has been linked to the fall of Rome (lead in the pipes); the cholera epidemic in 19th-century London (garbage in the streets); and many other significant events throughout history.

Though pollution has been around for thousands of years, the sources of our pollution problems have changed, and the amount of pollution has increased dramatically. A century ago, people were dealing with pollution from animal waste, coal ash, and open dumps. Today, pesticides, fertilizers, radiation, carbon monoxide, acid rain, and a lot of other «new» and toxic pollutants are the troublemakers. This increase in the number, and toxicity of pollutants, combined with an ever-increasing human population, has made pollution worse than ever before — threatening the very integrity of earth's life-support systems.

Hard to Pin Down: In this issue, we focus on air, water, and land pollution. However, in many cases the categories overlap. For example, pesticides can contaminate air, water and land, depending on how they are manufactured, used, and disposed of. Many pollutants also travel great distances and can change form, making it hard to pin down exactly where they came from.

Pollutants can affect different people in different ways. People with respiratory problems and allergies, for example, are often more sensitive to air pollution than people without these problems. Pollution does more than affect human health. It also limits our activities, harms wildlife and habitat, defaces buildings, and damages the planet's natural systems, including global climate patterns.

No Single Cause: Almost every human activity creates some type of pollution. And a combination of factors, from economics to politics, further complicates pollution problems.

Technological advances designed to make our lives easier, such as the internal combustion engine and plastics, have created some of our most pressing pollution problems. The lack of economic incentives to produce pollution-free products, as well as the fear that pollution controls will reduce jobs, lower our standard of living, and keep us from competing in foreign markets, are part of the problem too.

Not understanding the consequences of pollution is also part of the problem. For years, people thought that they could safely get rid of garbage, exhaust, and other waste products by throwing them away or releasing them into the air. But we're now realizing that the waste we dispose of can come back to do harm in a variety of forms.

Poverty and Pollution: Pollution is directly linked to social problems, such as poverty and overpopulation. In many cases, people on limited incomes cannot just move away from a chemical dump site or a smog-filled city. They can't afford to drink bottled water or pay for organically grown vegetables.

Weighing the Risks: We know that some pollution will always exist. But how much pollution is acceptable? What are the short- and long-term risks of a polluted environment to individuals, communities, and society as a whole? To deal with questions like these, policymakers are starting to rely on a relatively new process called risk assessment. Risk assessment helps people understand and quantify the risks caused by using certain technologies. But determining and evaluating risks is often extremely difficult. In many cases, data on the risks involved with new technologies don't exist.

A Question of Values In the past, we've spent most of our efforts cleaning up pollution rather than preventing it. First of all, preventing pollution saves money, protects resources, prevents health problems, and improves the overall quality of life.

But making the decision to prevent pollution involves values. Taking into account both short- and long-term risks, people must rely on their own value systems to decide how important it is to prevent pollution.
