Make our City Green
In many cities, with the rapid development of industries and business, the number of trees has dramatically reduced. Efforts are being made to prevent from cutting down more trees. However, many people still have never thought of the importance of green plants.
Making cities greener has many advantages. First, it can make air cleaner. Some researchers have proved that trees can reduce the amount of carbon dioxide in the atmosphere through absorption. Second, it can make our cities more beautiful. Finally, it can produce timber—an effective way to solve the problems of limited supply of natural resources.
Making our cities greener requires nationwide efforts. No one has the right to cut down a tree casually, and everyone should take an active part in tree-planting campaigns. We should do everything to add to the greening of our cities.
