Why rainforests are important?

Benefits of rainforests

Introduction

Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and increasing local humidity. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet.

Rainforests help stabilize the world’s climate by absorbing carbon dioxide from the atmosphere. Scientists have shown that excess carbon dioxide in the atmosphere from human activities is contributing to climate change. Therefore, living rainforests have an important role in mitigating climate change. But when rainforests are chopped down and burned, the carbon stored in their wood and leaves is released into the atmosphere, contributing to climate change.

BENEFIT #1

Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2 percent of Earth’s surface, rainforests house more than 50 percent of all plants and animals found on land.

BENEFIT #2

The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest. In the Amazon, 50-80 percent of moisture remains in the ecosystem’s water cycle.

BENEFIT #3

When forests are cut down, less moisture goes into the atmosphere and rainfall declines, sometimes leading to drought.n recent years, the rainforests of Borneo and the Amazon have experienced very severe droughts. These have been made worse by deforestation.Moisture generated by rainforests travels around the world. Scientists have discovered that rainfall in America’s Midwest is affected by forests in the Congo. Meanwhile, moisture created in the Amazon ends up falling as rain as far away as Texas, and forests in Southeast Asia influence rain patterns in southeastern Europe and China. Distant rainforests are therefore important to farmers everywhere.

RAINFOREST protect against flood, drought, and erosion

The roots of rainforest trees and vegetation help anchor the soil. When trees are cut down there is no longer anything to protect the ground, and soils are quickly washed away with rain. The process of washing away of soil is known as erosion.As soil is washed down into rivers it causes problems for fish and people. On steep hillsides, loss of forest can trigger landslides.Forests also play an important role in reducing damage from flooding by reducing the rate of water runoff.
