Graphic Truth: The Disappearing Amazon
Over the past fifty years, the Amazon rainforest has shrunk by an area equal to the size of Turkey. In the 1960s and 1970s, the Brazilian government supported settlement of the sparsely populated region for security reasons. Since then, huge swaths of the forest -- which is crucial for limiting the world's greenhouse gasses -- have been cleared for farmland used to feed Brazil's population and support its massive agricultural exports. Greater awareness of the environmental impacts in the 1990s produced tighter conservation regulations, though plenty of illegal clearing continues. In recent years, the annual deforestation rate has begun to rise again, and Brazil's new president Jair Bolsonaro has pledged to weaken regulations further in order to support businesses.
