Rainforest is being destroyed, but people are trying to keep it intact.  People settled in rainforests and much of it was destroyed.  Diseases spread to the natives, Yanomami, when miners came for gold.  Land was set aside for the Yanomami people and they got help from outsiders.  Much forest is lost due to logging for valuable wood and getting soy for the global market.  The government in Brazil is stopping deforestation by declaring land protected and they think the rainforest can be saved.
