The environment..

Good afternoon from Greece.. I discussed the environment with my English teacher about the environment.. It is a possible English exam topic which maybe ask me when i will be taking my English exams.. The earth is destroyed day by day.. In my opinion, there are so many solutions about to this situation... We can start by recycling the bottles and glasses which that we don't need.. We can use the public transport often many times instead of using to take our cars, or motor cycles and also we can also buy a bike... If we choose to buy a  the bike there are two advantages will 2.. The first is that we protect the environment as I said, and the other is we will begin to exercise the our bodies!!
What is your view??
