“Environmental pollution” is a term that refers to all the ways that human activity harms the natural environment. Most people have witnessed environmental pollution in the form of an open garbage mp or a factory pouring out black smoke. However, pollution can also be invisible, odorless, and tasteless. Some kinds of pollution do not actually dirty the land, air, or water, but they rece the quality of life for people and other living things. For example, noise from traffic and machinery can be considered forms of pollution.
Environmental pollution is one of the most serious problems facing humanityand other life forms today. Badly polluted air can harm crops and cause life-threatening illnesses. Some air pollutants have reced the capacity of the atmosphere to filter out the sun's harmful ultraviolet radiation. Many scientists believe that these and other air pollutants have begun to change climates around the world. Water and soil pollution threaten the ability of farmers to grow enough food. Ocean pollution endangers many marine organisms.
Many people think of air, water, and soil pollution as distinct forms of pollution. However, each of the parts of an environment — air, water, and soil — depends upon the others and upon the plants and animals living within the environment. The relationships among all the living and nonliving things in an environment make up an ecological system, called an ecosystem. All the ecosystems of the earth are connected. Thus, pollution that seems to affect only one part of the environment may also affect other parts. For example, sooty smoke from a power plant might appear to harm only the atmosphere. But rain can wash some harmful chemicals in the smoke out of the sky and onto land or into waterways.
Some pollution comes from one specific point or location, such as a sewage pipe spilling dirty water into a river. Such pollution is called point source pollution. Other pollution comes from large areas. Water can run off farmland and carry pesticides and fertilizers into rivers. Rain water can wash gasoline, oil, and salt from highways and parking lots into the wells that supply drinking water. Pollution that comes from such large areas is called nonpoint source pollution.
Nearly everyone would like to have pollution reced. Unfortunately, most of the pollution that now threatens the health of our planet comes from procts that many people want and need. For example, automobiles provide the convenience of personal transportation, but they create a large percentage of the world's air pollution. Factories make procts that people use and enjoy, but instrial processes can also pollute. Pesticides and fertilizers aid in growing large quantities of food, but they also poison the soil and waterways.To end or greatly decrease pollution, people would have to rece use of cars and other modern conveniences, and some factories would have to close or change proction methods. Because most people's jobs are dependent on instries that contribute to environmental pollution, shutting down these instries would increase unemployment. In addition, if farmers suddenly stopped using chemical fertilizers and pesticides, there would be less food to feed the people of the world.
Over time, however, pollution can be graally reced in many ways without seriously disrupting people's lives. For example, governments can pass laws that encourage businesses to adopt less polluting methods of operation. Scientists and engineers can develop procts and processes that are cleaner and safer for the environment. And indivials around the world can themselves find ways to rece environmental pollution. 望采纳！！！

Protection of EnvironmentThere are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reced with the rapid growth of modern cities.To protect the environment, governments of many countries have done a lot. Legislative steps have been introced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through ecation. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.保护环境目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。为了保护环境，各国*做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中*起着最重要的作用。我的看法是，为了保护环境，*应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育*付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

With the development of society, our living conditions are getting better and better. However, we humans have been doing harm to the environment by cutting down trees carelessly, throwing rubbish everywhere and pouring wastes without any treatment. We are now faced with serious problems, such as desertification, dirty water in rivers , poor air quality and global warming. I think it is everyone’s responsibility to protect our environment. We should plant more trees and flowers around us . We should stop factories from pouring waste water into the river and waste gas into the air. We hope our world will become more and more beautiful.
