Our era has been named the sixth mass-extinction and every day large parts of the rainforests are destroyed. It is estimated that 200 to 2000 animal species go extinct each year from deforestation. 

8. Limited farming potential

The deforestation for farming purposes is not very successful long-term since the soil can’t sustain crops for more than 1-2 years. The reason for this is because of the nutrient-deficient soil that is too acidic.

General Facts about Rainforests

Rainforests are characterized by their high amount of rainfall. But they differ depending on where on Earth they are located. A tropical rainforest has a warm and wet climate. These are usually found near the equator, about 10 degrees north or south of it.

Temperate rainforest, however, can be found in the so-called oceanic moist climates. They also receive a high amount of rainfall per year but is characterized by a milder climate with lower temperatures than the tropical rainforests.

The largest temperate rainforests can be found on the Pacific coast of North America.
