The Australian tropical rainforest is an important biodiversity hotspot. In a world dominated by humans, it is essential to preserve what helps keep us alive. The trees of the Australian tropical rain forest contribute to their environment by providing oxygen, climate amelioration, and supporting the wildlife. In an in-depth research done by Zachos, he found this information to be true. "One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen. This is enough to meet the annual needs of 18 people"(Zachos 319). These trees and plants are the source for many of the things that we use. Medical drugs, paper, and oxygen are just a few examples. Animals supply us with food and scientific research. However, Australia's tropical rainforest is being greatly affected by climate change. This is leading to a decrease in the biodiversity in the region. Biodiversity is the variety of living things in a specific geographic region. Biodiversity loss is a decline in the number of species, genetic diversity, or ecosystem. Over the past 200 years, Australia has experienced the most significant decline in biodiversity than any other continent. It is one of the most biodiverse countries in the world, meaning it has the some of the most vegetation and variety of species. With this in mind, reports have proven this statement correct." According to the Australian State of the Environment Report 2001, Australia harbors seventy-five percent of the earth’s total biological diversity. Australia has two of the world’s recognized 35 terrestrial biodiversity” (Zachos and Habel 312). The rainforest covers about 6-7 percent of the land surface and is home to many creatures. “The Tropics are characterized by their evergreen nature. It is home to at least forty-four percent of the world’s vascular plants and thirty-five percent of the world’s vertebrates” (Zachos and Habel 315). They are the last indication of an extensive e
