Today all people are happy because they celebrate mother earth.This celebration is global because more than one hundred and seventy five countries participate in it .
In my opinion , the things that we must do to protect the earth are:
1) our rational use of natural resources
2) to save energy
3) to reduce our traffic with cars
4) to move only with bicycles
Moreover , if you want to protect your earth , you must throw your rubbish in the bin . Finally , you must celebrate this day because earth is our mother and we have the advantage to protect it.
