Extreme Amazon

The Amazon River begins in the Andes Mountain in Peru. It travels about 6,000 kilometers to the Atlantic Ocean. It is the largest river in the world. It is also the second longest. Most of the Amazon's water comes from rain. During the rainy season parts of the river are 190 kilometers wide.

The Amazon River goes through the world largest rain forest. The Amazon rain forest is home to the highest number of plant and animal species on Earth. There are around 2.5 millions kind of insects, such as the world's largest ant. At least, 3,000 kinds of fish live there, and one-fifth of all the bird species in the world.

Some of the Amazon's animals are dangerous, such the anaconda, the largest snake in the world.

The Amazon is very important to Earth. If we lose the Amazon, we will lose a big part of life on Earth
