air pollution causes lung in fections, broncyties,and oter serious problems. water pollution leads to to disease called cholara,thyphoid,malaria etc. sound pollution affects our ears.... Our health is deteriorated as result of emission of carbon dioxide from the vehicles, and sulfur dioxide and nitroxide from industries. These gases are often trapped in the city, creating smog that could worsen asthma, impair lung function, and even cause death. Increasing pollutants such as carbon dioxide and chlorofluorocarbon can cause global warming and depletion in the ozone layer. When ozone layer is depleted, more UV rays can penetrate to our atmosphere, thus causing skin cancers. In fact, statistics show that there is about ten percent increase in skin cancer rate in the world since 1995. In addition, much of our groundwater is being polluted because farmers use chemical fertilizes, pesticides, and herbicides to raise their crops. These chemicals can seep easily from the farmland to the groundwater, causing diseases to us. It is not just we are affected by pollution; animals and plants are also affected by pollution. Animals and plants would become dehydrated from the extreme heat. Ice would melt more quickly, destructing the habitat of polar bears. Fish and other marine animals would die from oil leakage and the presence of untreated sewage in the sea.
