"Biodiversity is the sum total of all living organisms inhabiting the earth. It refers to the variety and variation in living organisms, their species, and their habitats. Global warming has emerged as a great threat to biodiversity. As the planet is warming up, plants and animals are trying to adapt to their changing environments. However, the pace of change is so fast that some living organisms are not being able to cope up with the challenges of nature. This is making some species vulnerable to extinction. Not only rising temperatures but also changes in rainfall patterns, breeding seasons, as well as the reducing interaction between animals and plants have endangered many species. It is believed that if global temperatures rise by over 3.5ÀC, up to 70 percent of the world's known species would go extinct."--
