    The Amazon rainforest covers 2.5 million square miles. It is the largest remaining tropical forest in the

world.It gets more than nine feet of rain each year.

    The Amazon is in South America. Almost two-thirds of the rainforest is in Brazil but it also stretches

across parts of Guyana,Venezuela,Colombia,Suriname,French Guiana,Peru,Ecuador and Bolivia.

    The first Europeans to discover the Amazon were Spanish,who found it while searching for gold and

silver tobring back to their king. The first people they met in the rainforest were female warriors,so

Francisco de Orellanamed the river after a Greek myth about women warriors called "Amazons".

   Even if the Amazon makes up only two percent of the earth's surface area,it is where more than half of

theworld's plant and animal species are. The Amazon has 60,000 types of plants,1,000 species of birds

and 300 typesof other animals. Jaguars,piranhas and pink freshwater dolphins are just a few of the animals that live in the Amazon rainforest.

    Because the Amazon is so large and____,it helps the world breathe a little easier by changing

carbondioxide into oxygen. The Amazon is also home to thousands of undiscovered plants and animals

that might be used

to cure diseases,like AIDS,one day. But uncontrolled development and forest fires are hurting the

Amazon.
