Global warming is the increase of the earth’s temperature due to the use of fossil fuels. It can have a negative impact on the health and living conditions of animals. The increasingly high temperatures disrupt the arctic ecosystem and change the time and place of bird migration. The climate change is due to the excessive release of Carbon dioxide, which absorbs heat. Some species may not be able to move fast enough to keep up with the shift in the location of their optimal climate conditions and they will die. Global warming is affecting animals in a negative way. Heat absorbed by the Carbon dioxide is melting away ice caps in the arctic, decreasing polar bear and ringed seal populations. It changes the course of a bird’s migration and mating time, which can affect the growth and reproduction of the species. The high temperatures are raising sea levels and harming aquatic creatures. In addition, the high carbon dioxide is destroying habitats, forcing the animals to leave their homes. Global warming should be slowed before it takes further tolls on the animals. Since humans are primarily responsible for the detrimental effects of global warming, they should take action to slow it down. Humans should plant more trees, because trees absorb carbon dioxide for photosynthesis when they produce oxygen. When trees are removed, less carbon dioxide is absorbed so more is present in the atmosphere. In addition, people should stop using fossil fuels, because they lead to the buildup of carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons in the atmosphere.
