Today the value of trees in our world is very high. Some people believe that cutting down trees is one of the most serious problems of our time, while others think that this is just a renewable resource that makes a person’s life better. Who is right? The question is controversial. I’m going to express my opinion.

Personally, I strongly believe that deforestation leads to a huge number of negative consequences. Firstly, cutting down trees leads to sharp temperature changes, changes in the amount of precipitation and wind speed. Secondly, many animal species disappear, because the destruction of the ecosystem leads to the death of almost all living things. Thirdly, the quality of life is deteriorating. It is both about the impossibility of the extraction of food, and the deterioration of the psychological state.

However, there is another opinion that deforestation is a necessary measure to improve people's lives. To begin with, wood is an excellent building material. Especially love to use it in the construction of buildings and furniture production. Also, some dry trees are dangerous to humans in times of natural disasters.

Undoubtedly, deforestation may be beneficial to humans. Yet, I insist on that this is a serious environmental problem because more and more territories become uninhabitable.

In conclusion, I can say that people need to change their attitude to nature. Each person can contribute to the revival of the world's forests by planting at least one tree.
