It covers much of the Amazon basin, which is 7 million square kilometers in size. Most of this land, about 6 million square kilometers, is actually covered by the forest.

This place is the largest and most biodiverse tropical rainforest on Earth. It holds an amazing 390 billion individual trees. These trees belong to about 16,000 different species. This huge area is shared by nine different nations.

The forest works in a very special way to stay healthy. It needs food to help its many plants grow. Every year, wind carries dust from the Sahara desert in Africa.

This dust travels across the ocean to the Amazon basin. It contains a mineral called phosphorus, which is vital for plant growth. About 182 million tons of dust blow out of the Sahara each year. About 22 million tons of that dust falls over the Amazon. This dust replaces the phosphorus that rain and floods wash away from the soil.

Humans have lived in this region for a very long time. Archaeological evidence shows people settled there at least 11,200 years ago.

In the 1500s, Francisco de Orellana became the first European to travel the length of the Amazon River. He named the area after the Amazons from Greek mythology. He saw complex civilizations living there during his travels. Some people thought the soil was too poor for many people to live. However, we now know that people managed the forest for thousands of years. They even created fertile soil called terra preta to help crops grow.

Today, the Amazon is home to more than 30 million people. These people belong to 350 different ethnic groups.

Indigenous peoples make up 9% of the total population living there. There are 3,344 formally acknowledged indigenous territories in the region. Most of the forest, or 60%, is located within Brazil. Peru holds 13%, and Colombia holds 10% of the forest. Other nations like Bolivia, Ecuador, and Venezuela also have parts of the rainforest.

It is important to understand how the forest is changing now. Large scale deforestation is happening in many parts of the forest. This can cause big economic losses for countries like Brazil. In 2023, the World Bank suggested new economic programs to help. Deforestation can also hurt farming so much that it leads to "agro-suicide."
