The future of the humankind can get in danger if the emission of carbon. dioxide and other poisonous gases go on in the same manner. These gases deplete the ozone layer and allow the ultra-violet rays of the sun to enter the earth's environment. This causes the rise in temperature of the earth and giving rise to the phenomenon called global warming. Increased temperature can melt the ice or the Antarctica, and cause other environmental problems, thus jeopardizing the future of human kind.
