Environmental pollution The nature is the most wonderful thing in the world. It gives us its loveliness to enjoy and to admire. The nature provides us with its riches: water and air‚ soil‚ mineral resources‚ flora and fauna‚ forests and fields. Nowadays situation is very bad‚ but just someone understand it. It means that many species of flora and fauna have already disappeared or are disappearing because of harmful actions of people. People have always polluted their surroundings. But until

Sea Pollution The pollution of the ocean is rapidly becoming a crucial problem on Earth. The major causes of sea pollution are oil spills‚ toxic waste‚ and dumping of other harmful materials into the ocean. This pollution will directly affect the living organisms in the ocean and indirectly affect human’s health and resources. We‚ as humans‚ should learn more about these in order to have the knowledge on how to solve this problem effectively. Oil spill is perhaps the most publicly acknowledged

Pollution‚ contamination of Earth’s environment with materials that interfere with human health‚ the quality of life‚ or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions‚ most is caused by human activities.

Air pollution Air pollution is a problem everywhere in the world. Local air pollution usually affects big cities. Air pollution becomes a worldwide problem when local pollution moves away from where it came from. For example‚ winds carry air pollution made in the middle of the western part of the United States to Canada‚ like acid precipitation. Acid precipitation Acid precipitation is precipitation‚ like rain‚ sleet‚ or snow‚ that contains acids from air pollution. When fossil fuels are burned

20014 Air pollution effect on humans There’s nothing quite like opening the door and breathing fresh‚ clean‚ air—but how clean is the air you’re breathing right now? Unless you’re a scientist with a chemistry lab at your fingertips‚ there’s no real way of knowing. The gases you’re sucking up through your nose could be slowly killing you: according to the World Health Organization‚ around two million people die prematurely from the effects of polluted air every single year. Air pollution has both

Noise Pollution Noise pollution is not a necessary price to pay for living in an industrial society. Much can be done to reduce the severity of the problem. For example‚ vehicles and other machines can be built to produce less noise. Four-cycle engines can replace much noisier two-cycle engines in such products as lawnmowers‚ motorboats‚ and jet skis. Labels that indicate the noise levels of appliances and tools can help consumers avoid noisy products and choose quieter alternatives. Even
