Review of literatureI. Introduction-Global WarmingAs the debate continues on how to protect the Earth for the future of man's existence, there is no doubt about the profound impact that pollution and rising global temperatures have had. There are some natural causes for these changes and several man-made reasons for the modification of the Earth's environment. These sources of global warming and pollution are adding to an already complicated ecosystem. They affect Earth's biomes and disrupt the balance between organisms that populate many climates. Finding the source of the problem can be quite difficult, but scientists and climatology studies work hard to find patterns in Earth's changes in temperature and atmosphere. When looking at how Earth's biomes have changed, many think of global warming as a major factor. According to Dictionary.com, “global warming is an increase in the Earth's average atmospheric temperature that causes corresponding changes in the climate and may result from the greenhouse effect.” The theory of global warming assumes that the Earth maintains a constant average temperature. This is believed to be the result of a balance between the amount of sunlight the Earth absorbs and the amount of IR (infrared radiation) the Earth constantly emits into space. This theory states that the lower atmosphere must react to the energy imbalance by losing less infrared radiation than the solar energy absorbed by the rising temperature. This would cause an increase in IR escape into space until the infrared radiation equaled the amount of sunlight absorbed. In other words, the Earth must increase its temperature until its energy balance is stable... center of paper... life in the ocean. It would lower the amount of calcium carbonate in the water. Calcium carbonate is used by marine organisms such as corals, molluscs, crustaceans and molluscs to build their shells. If the pH level dropped as expected, there would be a 60% loss of calcium carbonate. This would make the survival of thousands of marine species incredibly difficult. Global warming and pollution are changing the Earth's climate every day. Together they are increasing, leaving the polar ice caps and rainforest with a higher risk of survival. Most of the global warming and pollution of the Earth is due to the senseless waste of human beings. By paying more attention to Earth's ecosystems, the path Earth has taken could be reversed. Earth is a delicate planet and every biome that inhabits it is essential for human and animal survival.
