biodiversity is lost‚ or natural resources are depleted‚ the environment is hurt. Environmental degradation can occur naturally‚ or through human processes. The largest areas of concern at present are the loss of rain forests‚ air pollution and smog‚ ozone depletion‚ and the destruction of the marine environment. Pollution is occurring all over the world and poisoning the planet’s oceans. Even in remote areas‚ the effects of marine degradation are obvious. In some areas‚ the natural environment

It is tri atomic oxygen (03) and is a gas found in the troposphere as well as in the stratosphere. Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while

Some of these problems are air pollution‚ water pollution‚ rain forest destruction‚ smog‚ overpopulation‚ and global warming. The worst problems now affecting the world are global warming and overpopulation. First of all‚ global warming‚ which means increasing the temperature of the earth‚ is the most dangerous one. There are

So many industries are being produced‚ pollution is a major problem. The industries need a lot of water‚ and/so the water is getting contaminated. This problem helps explain China’s water shortage because smog is smoke and fog so it can make you sick just breathing it in. Factories are growing which leads to contaminated rivers. Documents D and C. It is true that there are factors contributing to China’s water scarcity because there is too high of a demand

because of the hole in the ozone layer caused by air pollution. [6] This pollution traps heat around the Earth thus causing global warming. [7] Smog is one of the forms of air pollution and one of its main components is sulfur dioxide. Although it causes acid rain it also is able to keep sunlight out of the Earth maintaining it cool. Thus reducing smog is actually helping even more the global warming as it lets more sunlight go through and gets trapped thanks to the pollution. [7] Some of the other

Advocates for clean air have also presented evidence that the increase in the use of ethanol in gasoline actually has increased greenhouse gasses and smog in American cities. Ethanol blended gasoline may be more volatile than conventional gasoline causing the production of more hydrocarbons. It is also more likely to seek through the seals and gaskets of an engine which also releases hydrocarbons into

It has been coined as such because of the diversity and lack of homogeneity of this population‚ which stands in sharp contrast with the baby- boomer generation.
