We often think of the Amazon rainforest as a vast expanse of nature untouched by humans. But a new study suggests that's not true -- in fact, today's rainforest is shaped by trees that were cultivated by indigenous peoples thousands of years ago.
A similar story could be said about Australia. It used to be lush and green because the indigenous people there had worked with the land to help make it that way. That all turned to the famous red desert outback after it was colonized. All the ancient knowledge of the land was destroyed and all that work had come undone.
