In fact,we can do something within our power.For example,

Recycle the wastepaper and protect trees
Eat whole food in stead of processed food.
If you can ,don't drive the car.
Don't eat wild animals
We can only do that ,but also tell others.Make us a volunteer of publicising to protect earth,to make more people join us.
