Humans burning of fossil fuels such as coal and oil and natural gas in nearly a century. A large amount of carbon dioxide emissions of greenhouse gases. These greenhouse gases to the shortwave radiation from the sun has high permeability. The longwaves radiation reflected on the Earth that highly resorptive include invisible electromagnetic pollution which call "greenhouse effect" also can cause global warming. The forests in the world can be divided into frigid northern (main) forest, temperate forests and rainforests. And for now on, all of the primeval forest logging industries are being developed on a large scale to all the objectives of. Many tropical forests is already disappeared in the past 50 years been logged completely.
