Animals are essential to maintain the circle of life and the food chain. It is just not the animals alone, insects, reptiles, and the aquatic life are all interdependent on each other, and on theplants and humans as well. The climate change affected the behavior of animals causing them to reproduce earlier or later than usual, causing an imbalance in the ecosystem and being in places where theycould never be for the weather, this affects other animals they have to change their place or time to reproduce to survive. One example of an animal species that is already being threatened by theeffects of global warming is the polar bear that inhabit parts of Canada as well as the Arctic. In both cases, it appears that polar bears are already beginning to suffer as their environment becomesthreatened by the onset of global warming. Many polar bears along the eastern shore of Canada may eventually starve to death as their main source of food (fish) begin to disappear due to the disappearingglaciers and polar ice caps.

Plant life is also threatened by the growing threat of global warming. As with animal life, much plant life thrives in specific ecosystems. As a global climate changebegins a global climate shift, many ecosystems on earth may not be able to survive these sudden shifts in climate change. This means that many delicate plant ecosystems are already being threatened bythe rise in global temperature, and more plant species and their ecosystems will surely be threatened as the effects of global warming are more widely felt throughout the world. Over the past decade,global warming has increased the number of forest fires affecting numerous areas of the world. This is caused by record high temperatures and drought. These fires, in return, add to the greenhousegases in the atmosphere. As temperatures in regions begin to rise, plants are beginning to grow in other areas they are normally not found in. They are trying to adapt to the global warming changes....
