The environment is everything around us, for example,air,water,animals,plants,buildings,and so on.They all affect us in many ways and closely related to our lives.People can't live without the environment.Everybody needs to breathe air,drink water and eat food every day.We bury cocal tokeep warm ,and we use wood to make paper.As a result,we become the part of the environment. The environment has been getting wores and wores for many years.We have upgrading ourliving standard,meanwhile the environment has been polluted.Somke form factory chimneys pollutes the air.Machines and decreasing every minute.Streets are crowed with people and vehicles.The environment painful for us to live in it now.So it's time to solve those prombles. Fortunately,it isn't too late to correct our mistake.People are coming to realize the imprtantceof the environment.We have begun to try our best to improve it.Laws are being made dealing withair, water and noise pollution.The river be brighter, the sky will be clearer,the flowers will be more beautiful, and the sunbeam will be more dazzling and pretty. We believe that we will be able to save our environment and live in a better world. 环境围绕我们身边,例如:空气,水,动物,建筑等。它们从各个方面影响着我们的生活,与我们的生活密切相关,人们离开环境就无法生存。每人每天都要呼吸、喝水、和吃东西。我们烧煤取暖、用木材造纸。结果,我们也成为环境的一部分。 很多年以来,环境日益恶化。我们在提高生活水平的同时,也在导致环境污染。从工厂烟囱里冒出来的烟污染空气,机器和引擎经常发出恼人的噪音。因为森林每分钟都在减少,使动物们无家可归。街道上挤满了人和车辆。环境在我们生活中是最重要的,但是现在它已经让人们讨厌。所以,该是解决这些问题的时候了。 幸运的是,现在改正错误还不晚。人们意识到环境的重要性。我们已经开始尽力改善环境法律也开始涉及到空气、水和噪音等问题。将来,河流会更清澈,天空会更晴朗,花朵会更鲜艳,阳光会更灿烂、更温暖。保护环境会使我们在一个更加美好的世界中。

“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 dump 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 reduce 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 reduced 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 reduced. Unfortunately, most of the pollution that now threatens the health of our planet comes from products 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 products that people use and enjoy, but industrial 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 reduce use of cars and other modern conveniences, and some factories would have to close or change production methods. Because most people's jobs are dependent on industries that contribute to environmental pollution, shutting down these industries 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 gradually reduced 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 products and processes that are cleaner and safer for the environment. And individuals around the world can themselves find ways to reduce environmental pollution. 望采纳。
