Over the last decade, Brazil has seen a lot of growth (and yes, some big declines), they've landed both the Olympics and the World Cup, and they've (so far!) pulled off both with no headlines worse than Ryan Lochte's head-scratcher of an incident. That's pretty good. One accomplishment bigger than that is what they've done to save the rainforest, which they've managed at a very reasonable cost.
Yes, a lot is still being consumed, and more could be done, but the rate at which it was disappearing has slowed greatly. That's something to really be proud of!
