Dear friends,
Our hometown is facing serious environmental problems now. The air is filled with dust and harmful gases from factories and cars, making it hard to breathe sometimes. The rivers are dirty as people keep throwing waste into them, and there are fewer fish now.
The main causes are that people don't have a strong environmental - protection awareness. They litter everywhere and factories don't deal with waste properly.
Here are some suggestions. First, we should plant more trees to purify the air. Second, it's necessary to recycle waste to reduce pollution. Third, we must stop throwing litter into rivers.
Let's take action now and make our hometown a more beautiful place!
Yours,
Li Hua
