Effects on environment - Research Paper Example Pollution is contamination of the natural environment and which brings about environmental degradation. Air pollution caused by industrial emission of carbon dioxide, carbon monoxide, sulfur and other harmful gases leads to depletion of the ozone layer which acts as a shield to protect the earth from excessive and harmful sun rays. Water pollution on the other hand which may be caused by harmful farming, mining and even industrial wastes destroy the environment by exposing it to toxic chemicals and hence killing animals and plants which depend on that water. It also leads to destruction of the soil hence rendering the area inhabitable. The excessive population growth that has been witnessed over the last century has also had its effects on the environment. The major effects include deforestation, depletion of natural resources and extinction of species of both plants and animals. As the population continues to expand and with limited land for settlement, the only alternative left is to start clearing forests and even draining swamps in order to build settlement areas. This leads to climate changes and environmental degradation. The minority species are also displaced in a â€Å"battle for the fittest† as explained by Darwin. Species like that of dinosaur which occupy large areas are killed to clear space to accommodate the excess population. Population growth also leads to increased construction which not only causes pollution which as explained earlier degrades the environment but also leads to deforestation and extraction of earth’s important minerals in the process of construction. Other environmental influencers do not however entirely bring about negative effects on the environment. Some farming techniques for example like animal farming enriches the environment by ensuring provision of manure and hence minerals. Practicing biological methods of farming where no chemicals are used also prevents degrading
