Ozone Pollution. Ground level or bad ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.
Pollution is another cause of environmental degradation. Pollution is caused by releasing harmful gasses in the atmosphere and also when deforestation occurs. Deforestation results in more quantity of carbon di oxides in the atmosphere and that is a pollutant thus deforestation causes pollution.This has a lot of adverse effects in the atmosphere. Impact of Deforestation and Pollution. One of the major problems which these two cause is the greenhouse effect.The greenhouse effect is when the harmful ultraviolet rays of the sun are trapped inside the atmosphere because of the excessive amount of carbon di oxide in the air.eforestation results in more quantity of carbon di oxides in the atmosphere and that is a pollutant thus deforestation causes pollution. This has a lot of adverse effects in the atmosphere.
