Just where do you start when you want to "save the planet"? And in which areas should you focus most of your efforts? In a rather brave thought experiment, the Environment Agency has assembled a group of the country's leading environmental experts to draw up a list of actions that we should all undertake if we are to try to avert the environmental horrors so often forecast if we continue with our "business as usual" lifestyles. This list contains suggestions for government, companies, councils, religious leaders, scientists and others to consider, but it also includes actions that individuals can attempt. More unusually, though, it lists the actions in order of priority. |
“ Environment Problems ” |
A variety of environmental problems now affect our entire world. As globalization continues and the earth's natural processes transform local problems into international issues, few societies are being left untouched by major environmental problems.Some of the largest problems now affecting the world are

| “ Global Warming ” |
 |
Global warming is called the greenhouse effect because the gases that are gathering above the earth make the planet comparable to a greenhouse. By trapping heat near the surface of the earth, the greenhouse effect is warming the planet and threatening the environment.Many scientists criticized Mr. Hansen's report, and the debate over global warming continues today.Current fears stem largely from the fact that global warming is occurring at such a rapid pace. Models are predicting that over the next century, the global temperature will rise by several degrees.Some scientists still do not think that the effects of global warming are as severe as some people say. They think that droughts, hurricanes, and floods often blamed on global warming might actually have other causes.One major difficulty in studying global warming is the fact that weather data only exists for the last century and a half. As a result, understanding the present and predicting the future are very difficult.

| “ Air Polution ” |
 |
Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air.Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles.Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time.The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air.

| “ Acid Rain ” |
 |
Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants.
Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments.
For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natural causes as well. Recently, more intensive research has been done so that countries have the information they need to prevent acid rain and its dangerous effects.

| “ Water Pollution ” |
 |
Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually.The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another.For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today.As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution.
