Because Brazil's economic prosperity in the last two decades is increasingly linked to the Amazon's good health, restoring the country's economy is a critical first step toward ending deforestation.

One-fifth of Earth's land could be restored to wilderness by reintroducing animals and improving management.

Deforestation in Brazil recently reached a 12-year high, prompting France to cut soybean imports from the country.

Forest that has been disturbed – but not cleared – by logging or fire can be hard to spot from satellites.

Mining strips nitrogen from the soil and means the forest struggles to grow back even after mines are abandoned.
