South America is home to the largest tropical rainforest in the world, the Amazon rainforest. This forest is nicknamed ''the lungs of Earth'', and that's because it produce the largest amount of oxygen. Not just that it produces the most oxygen, but this rainforest has the highest biodiversity, both of plants and animals.

If the South American countries develop in a non sustainable manner and the Amazon forest is destroyed, the implications for the whole world would be very bad. The global temperatures will rise, the pollution will rise, and many industries will suffer because they will lose their materials.
