Air pollution problems such as smog and acid rain result from the presence of, and interactions among, various air pollutants released to the atmosphere through natural processes and human activities. Natural sources of air pollution include forest fires, volcanoes and emissions of volatile organic compounds <span> from vegetation. Human sources of air pollution include activities that rely on carbon-based fuels, for example, </span>transportation<span>, </span>electric utilities<span>, industrial processes such as </span>oil and gas production, as well as certain products, such as paints and solvents. Deforestation carried out to create dry lands is one of the major concerns. Land that is once converted into a dry or barren land, can never be made fertile again, whatever the magnitude of measures to redeem it are. Land conversion, meaning the alteration or modification of the original properties of the land to make it use-worthy for a specific purpose is another major cause. This hampers the land immensely.
