Global warming is an overall increase in world temperatures which may be caused by additional heat caused by the sun being trapped by greenhouse gases. Global warming is the caused by pollution which comes from the high producers of carbon dioxide and other gasses, the burning of coal, and methane that is produced by cattle which travels into the Earth's atmosphere. I just want to place in a point to tell people that Global Warming is not a good thing so just keep in mind to turn off all electrical appliances when they are not in use because the process of making electricity is a big producer of green house gasses and it will save you a lot of money. There has been a treaty called the Kyoto protocol. The objective of this treaty is to decrease the amount of greenhouse gas emissions. It was introduced on 11 December 1997 and it entered into force on 16 February 2005.
Its really hard to find the good things about such a negative topic. The cold winters will get warm which is healthier. Scientific studies show that there will be 40,000 less deaths each year in the US. In Britain, scientists estimate that about 30,000 deaths a year are related to cold winter weather. Warmer temperatures in the US will reduce medical costs by about $20 billion every year.
On the negative side, Higher Sea level which causes flooding in low land areas which causes deaths and diseases to many people and animals, also farm growth will be destroyed and the animals which lead to lack of food. And another disadvantage is that there will be more natural disasters like tornadoes, typhoons, Tsunamis and much more.
My opinion on global warming is that it is a big problem the world is facing today which needs to be fixed before it gets out of hand. We need to fix this problem because if we don't Earth will be in trouble and we will be suffering for it. If this problem arises there will be more droughts, more natural disasters and more diseases caused by flooding on low-lying lands. In most countries like Mexico the air is so poisonous that just breathing the air you will get sick or get severe migraines. This problem might increase if nobody does anything about it and it might spread to other countries.
