Good morning, everyone!
Nowadays, the smog weather frequently occurs in our city. This kind of weather is of great harm to our health.
It is obvious that air pollution is the main factor that has resulted in the frequency of smog weather. And the reason for air pollution is various. Smoke from burning fossil fuels and all kinds of dust released from factories are important factors. Besides, exhaust emissions from cars and buses have made the situation even worse.
We are supposed to reduce the use of fossil fuels and boost the use of public transport facilities, aiming to cut down the carbon dioxide emission.
Thank you!

How can we reduce garbage pollution? 
The problem of garbage pollution is getting so serious that many cities around the world are now being surrounded by garbage.
To solve the problem of garbage pollution, we are supposed to take some effective measures. First, we should sort garbage properly so that it can be treated easily. Besides, reusable garbage should be recycled.
In my opinion, only if we work together to reduce garbage pollution can we live in a better environment and leave a more beautiful world for future generations.
