Dear fellow students
With the development of industry, our environment is getting worse and worse. Environmental problems linked to climate change pollution and forest coverage decline can be seen worldwide, attracting people's attention.
To answer the call of planting more trees, we call on everyone to plant trees. As people detect, carbon dioxide is partly to blame for the greenhouse effect, which trees can absorb. Therefore, the idea of planting trees rooted in our mind is an effective way to fight against global warming. It is everyone's responsibility to protect our earth. Let's plant trees around and in the distant mountain. We can also donate money to tree-planting projects, hoping it generates better results.
Dear friends, we have only one earth. Let's take action from now on!
