Third largest Dam got the green light to be built in the Amazon

Above is a map that shows the impact that the dam will have on the area.

Building the third largest dam in the world is having a lot of debate by environmentalist and also the director of the movie Avatar James Cameron. They believe that the dam should not be built because it will have huge implications on the amazon and it is the worlds largest rain forest and it should not be destroyed. The Amazon forest has the largest number or species that could have medical cures.
I believe that the rain forest should not be destroyed because we are going through the huge issue of climate change. If we destroy such a large area of vegetation it will impact the natural cycle that exists and will affect the world in time.
