I want to share and discuss ideas related to keep our environment green.

The first thing I want to share is aquatic raft.The rafts are made from pontoons and wood planks, with each cluster being 150-200m from each other. Each raft is anchored with ropes to stop them from floating down river during storms or floods. Also, aquatic plants are planted on the rafts. the aquatic plants play a role in cleaning polluted water, due to their roots and bodies that filter water, converting polluted compounds into biomass and releasing oxygen into the water. This kind of raft is applied in some lakes of Hanoi. I think it is really useful? Do you think so?

I think the underlying reason for the stituation of mining is human's avarice. If they don't want to draw out big profit from some kinds of chemical substances, they will not dig many mines and do harm to environment. And by the way, I think that if we raise highly concern for alternative resources, we may reduce the possibility of violating environment. Do you think so?
