Global Warming

One of the most problem that make global waming is burning forest. Million of hectares of trees are burnt each year. And it is actually more than this, the factories is also the major problem. Like I say one the other post. Every a hundred years the Earth tempretures is increasing more than 5 degress celsius. By this driught will easily happens also. Land are dried and no water. People will die because of thirst and hunger. Plants and crops will not produce rice and the supply of rice will decrease and the price of rice is going to be more expensive. More if they are living right on the equator where it is very hot and they will get the hottest tempreture on Earth. The sunshine from the sun must enter the Earth but no the ultraviolet. The ultraviolet makes the world becomes hotter and it made people got skin cancer. The ultraviolet needs to bounce back to the space because of the ozone layer, but because the ozone layer have wholes the ultraviolet rays shines to the Earth. Actually if the ozone layer covers the world 100% the ultraviolet will still come to the Earth due to the air pollution that made the ultraviolet block to bounce back to the space. The ozone layer is weak due to the pollution that is very much in the atmosphere. More than tons and tons of carbon dioxide is sent to the atmosphere. Can you imagine carbon dioxide which is a liquid can reach to tons. That's amazing, so yeah it's horrible.
