What Can We Do for Our Planet?

My dear Students,
I am glad you've joined our Nature Protection School Project! You've already heard that our planet is in danger. Every day we damage it by driving, throwing out a lot of garbage or just using non-recycled bags in supermarkets. It can lead to undesirable things. But we can prevent it! 
So, have a look at this video and comment it. Mention what types of contamination exist in the world and how they harm our planet.
