It used to be wonderful everywhere--clean air, clean sky and clean water. However, technology has developed, and human beings broke the peaceful balance for their own convenience. Our vision for a sustainable world is that humans will be willing to live in harmony with our nature once again.

Indeed we cannot stop world economy development, but we can acheive this goal of sustainability by changing our behaviors in daily lives.

1. We shouldn’t waste energy. We should turn off electric appliances when they’re not in use, and we shouldn’t leave air-conditioners on for the whole day, especially when people are not there.
2. We should reduce greenhouse gases. We can walk instead of drivion or riding vehicles and take public transport if we want to go to a far place. We can bring our own chopsticks instead of using disposable utensils.
3. We should choose detergents cautiously and avoid cleaning agent containing phosphate.
4. We shouldn’t litter everywhere. Wind may blow it into oceans and it will lead to tragedies.
5. We can plant trees. It can help reduce CO2 and clean our environment.
6. We have to economize on water to avoid water shortage.
