Ecosystem Lecture

Ecosystem lecture finished today. It was so interesting. That lecture about Ecosystem. Ecosystem is environment of animals, plants, and other living things in this planet; the earth. This system is so intersting and misterus!! And it was very important for all life. But it was destructed by human acftivities. What can we do for the issue? Should we do for the problem.... I feel that it is very difficult to solve it .
