1. If my home installed a solar water heater, we would save a lot of energy.

2. If all households in Viet Nam turned off lights during the Earth Hour, we would save enough electricity to develop our rural areas. 

3. If students in our school didn't throw litter on the school ground, our campus would look greener and fresher. 

4. If people used glass bottles, they would use it again and again. 

5. If we installed a wind turbine, our school would become more eco-friendly. 

6. If people used organic fertilizers, they could prevent land pollution. 

7. If people rode bikes, they would keep the air less polluted.

8. If that factory had a wastewater treatment system, the river wouldn't become so polluted.
