what can we do to protect our beatiful home

In today's society, with the development of the society, our beautiful homes have been destroyed, and we should protect our homeland. Then how should we do?I think we should do the following:
First, we should actively participate in energy-saving emission reduction activities to do.
Second, don't throw garbage, not arbitrarily picking flowers and candy trees.
Third, walk or bike to school. And so on.
All in all, the protection of our beautiful homeland is the responsibility of every citizen is our obligation. Therefore, we strive to protect our homeland. Create a better life.
