It's a known fact that the Amazon rainforest in Brazil is responsible for one-third of the world's oxygen. That natural inhabitants of the canopies, such as howler monkeys, blue macaws, and jaguars, are in constant threat due to bulldozing, woodcutting, and forest deconstruction. And we've all seen Rio, right? Poaching of endangered species will lead to no more dancing and singing birds! Well, by sending letters of encouragement to missionaries and wildlife organizations in South America, you'll find that more trees will be planted, the different species of the different territories will be rescued from poaching and endangerment, and we will have more air in one of the world's most lush and beautiful countries on Earth.
