Amazon Rainforest
Deforestation (often to create more pastures and cropland) poses the biggest threat to the largest rainforest on the planet, though rates have slowed in recent years. Home to millions of species, the Amazon is one of Earth's last refuges for jaguars, harpy eagles and pink dolphins. At the current rate of deforestation, more than half of the 1.4 billion acres of rain forest could be gone by 2030. What to see now: Embark on a canopy tour through the rainforest and see the extraordinary wildlife from a different point of view. Canopy tours eliminate much of the environmental impact of trekking through the jungle floor so you can feel secure you're leaving less of a mark.
