Running through 8 countries from the Andes to the Atlantic Ocean and passing through the Amazon Rainforest, the Amazon River is the largest river in the world in terms of volume. It deposits 12.6 million liters of water per minute in the Atlantic Ocean. It is also the second longest river in the world, standing behind only the Nile River in Egypt.

The forest took more than 50 million years to form.

It is believed that more than 5 million people inhabited the Amazon Rainforest at one point. By 1980 its population stood at less than 200,000. Nowadays, there is an estimated 2,500 people inhabiting the forest.

The Amazon Basin covers an area of 7,000,000 square kilometers, of which 5,500,000 square kilometers are covered by rainforest. Currently, the Amazon Rainforest represents half of all the world’s rainforests. In fact it is so large that if it was a country it would be the 9th largest in the world.

The forest is sometimes referred to as the “lungs of the planet” because it produces around 20% of the world’s oxygen.

There are around 3,000 known edible fruits species in the amazon, of which only 200 are cultivated. The natives eat around 1,500 of all these species.
