Today is World Rainforest Day. Find out why rainforests are unique

Today is World Rainforest Day. Home to nearly half of the planet’s plants and animals, rainforests perform the crucial function of absorbing carbon dioxide and stabilizing the climate pattern.

Tropical rainforests are home to nearly 30 million species of plants and animals, according to the On World Rainforest Day, it’s important to remember three things: Protect forests, Restore habitats and Support sustainable livelihoods.

What are rainforests?

Rainforests are the oldest living ecosystems on Earth. Incredibly diverse and complex, some of the rainforests are “surviving in their present form for at least 70 million years.” These forests typically receive over 2000 mm of rainfall every year. Some of the largest rainfotests are the Amazon in Brazil, the rainforests of Congo in Africa and Indonesia. Tropical rainforests are also found in the Pacific and Caribbean islands.

Rainforests are unique in terms of structure as well. Most of them have four layers: emergent, canopy, understory, and the forest floor. Each layer is different and there is fight for sunlight among the plants. The levels of water, sunlight and air is different in each layer. This makes rainforests an interdependent and complex ecosystem.
