Tropical rain forests belong to a broader forest group called tropical moist forests, of which there are numerous different types. Forest scientists discriminate rain forests from other types bearing in mind factors such as temperature, rainfall, length of dry season, and altitude. Rain forests in addition play a significant role in global climate regulation by engrossing carbon dioxide, a gas alleged to be to some extent accountable for global warming. Plants in nature soak up carbon dioxide and give off oxygen gas in the process of photosynthesis, and tropical rain forests absorb more carbon dioxide than any other terrestrial ecosystem on earth. Global emissions of carbon dioxide have increased nearly 30 percent in the last century. There is general agreement among the scientific community that by absorbing some of the gas, rain forests play a vital role in lessening its impacts.
The tropical rainforests of the world are an important and crucial part of our planets ecosystem. At present the rainforests are being exhausted at alarming rates. The causes for rainforest depletion are mainly due to human activities, such as ranching, agriculture, and urban development. These areas must be monitored in order to provide current and complete information in order to better understand and protect the rainforests. In today's world population growth has presented a main apprehension for a lot of reasons. One of these concerns is the devastation of tropical rainforests. Tropical rainforests once covered 14% of the Earth's shell. At present the rainforests have dwindled to 6% of the Earth's surface, and estimates have been made that predict the total loss of rainforest in 40 years. One and a half acres of rainforest is lost to development and industry every second. An estimated 50,000 species of plants and animals become extinct every year due to deforestation by man........
