Introduction to Global warming
Global warming is a problem which has happened for several years. There are some causes of this problem which are man-made and some natural causes. In this essay I’m going to write about them.
Natural causes are causes created by nature. One is due to the emission artslike a greenhouse of methane gas from the tundra region. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another cause is that the earth goes through a cycle of climate change which lasts around 40,000 years.
Man-made causes probably do the most harm. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many types. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.
Another major man-made cause of Global Warming is the population. More people need more food, and more methods of transportation. That means more methane because there will be more burning of fossil fuels, and more agriculture. Agriculture is going to be damaged by Global Warming. Are you smell something terrible from a barn filled with animals? You're smelling methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem with the increasing population is transportation. More people means there are more cars, and more cars means more pollution. Also, many people have more than one car.
In my opinion Arctic and Antarctic will see reciting in a few years. So we must solve this problem for other generations.

The ideas which about the Global warming is very nice. You mention many reasons and explain it in a good way.But I think you write many causes and ignore to explan some of it with examples.Also you dont explain what is the titlle which is the Global Warming.Finally you give good causes about this subject.Keep doing hard.
In your essay you mentioned the causes of the global warming but they were too long. In the future try to write a shorter essay and try to combine the paragraphs with the same idea. Another thing is that I noticed that you didn’t give a general idea about the global warming. You didn’t state what the global warming is…… I hope to read a better essay in the future.
Good luck
