Learn about tropical and temperate rainforests, how they contribute to the global ecosystem, and the conservation efforts to protect these biomes. Rainforests are home to over half of the world's plant and animal species.
A rainforest is an area of tall, mostly evergreen trees that receives a high amount of rainfall. Rainforests are likely Earth’s oldest living ecosystems, with some surviving in their present form for at least 60 million years. They are incredibly diverse and complex, with more than half of the world’s plant and animal species calling ...
Found on every continent except Antarctica, rainforests are ecosystems filled with mostly trees that typically receive high amounts of rainfall. Tropical rainforests are found near the equator, with high average temperatures and humidity, while temperate rainforests lie mostly in coastal, mountainous areas within the midlatitudes.
The Amazon Basin supports the world’s largest rainforest, which accounts for more than half the total volume of rainforests in the world. Occupying much of Brazil and Peru, and also parts of Guyana, Colombia, Ecuador, Bolivia, Suriname, French Guiana, and Venezuela, the Amazon River Basin is the world’s largest drainage system.
The Amazon rainforest plays a crucial role in keeping carbon out of our atmosphere, as it naturally sequesters about 28% of the atmospheric carbon emitted by the burning of fossil fuels elsewhere. But, it can only remain a carbon sink as long as it absorbs more carbon dioxide than it releases.
Rainforests are home to over half of the world's plant and animal species. Learn about tropical and temperate rainforests, how they contribute to the global ecosystem, and the conservation efforts to protect these biomes.
High on a tower overlooking the lush Amazon canopy, Gisele Bundchen and Brazilian climate scientist Antonio Nobre talk about the importance of the rainforest and the impact of cutting down its trees.
Estimated to be twice the size of India and contain 10 percent of the world’s known species, the Amazon rainforest is a critically important ecosystem — but not just to the plants and animals that call it home.
About a year ago, my brother and I heard about two girls who started their own nonprofit organization, Kids Saving The Rainforest when they were just nine years old. Their goal was to save the lush rainforests of Costa Rica, where they were living at the time.
Rainfall can vary across grasslands from season to season and year to year, ranging from 25.4 too 101.6 centimeters (10 to 40 inches) annually. Temperatures can go below freezing in temperate grasslands to above 32.2 degrees Celsius (90 degrees Fahrenheit).
