Global warming is a big problem in the world today. There are many reasons for this problem and we need to find some solutions to fix it.
First, the main reason of global warming is pollution from factories and cars. Every day, many factories burn coal and oil to make electricity. This makes a lot of bad smoke and carbon dioxide go into the air. Also, there are too many cars and motorbikes on the street. They also produce a lot of smoke. Second, people cut down too many trees in the forest. Trees are very important because they help to clean the air. When we don’t have enough trees, the air becomes hotter and warmer.
To solve this problem, we can do many things. First, the government should make more public transport like buses or trains. If people use buses, there will be less cars on the road and less pollution. Also, we should use green energy like solar energy or wind energy because it is clean. Second, normal people can help too. We can plant more trees around our house or at school. We should also save electricity by turning off the lights when we do not use them.
In conclusion, global warming is dangerous because of human activities like burning oil and cutting trees. But we can stop it if governments and citizens work together to protect the environment.
