A letter describing the bad effects of climate change

 Write a letter to a friend describing the bad effects of climate change

Dear Sima,

 I received your letter last week asking me for a description of global warming, so in this letter, I'm going to talk about global warming. Global warming is the increase in the temperature of the earth which can harm people and all things on the planet. Global warming is caused by the greenhouse effect, and the greenhouse effect is caused by many gases, but it is mainly caused by carbon dioxide.

Deforestation is the first reason, and after the development of industry, it causes so much pollution that it is also harmful to the atmosphere. Then the waste water from the industry also damages the soil and the atmosphere. And people look for as many trees as fossils, furniture, firewood. And when they cut down trees, the carbon dioxide in the atmosphere is not converted into oxygen, which causes global warming. The hole in the atmosphere causes many skin diseases.

Be careful not to cut down trees and keep planting more trees, we'll talk about that in the next letter. Say hello to your sister and my salam your parents.

 Your lovely friend
