Importance of Forests and Their Conservation

1.Which Forests Are Called the Lungs of Earth, and Why?

• The tropical rainforests are called the lungs of Earth.
• Plants absorb carbon dioxide from the environment during photosynthesis and release oxygen into the atmosphere, which is necessary for survival.
• The Amazon rainforest is the world’s largest rainforest which absorbs a considerable amount of carbon dioxide from the environment and releases oxygen.

2.What Is Forest Floor? How Is It Important?

• The ground surface beneath the trees of a forest is called the forest floor.
• A forest floor is rich in flora and fauna. It is composed of grasses, fungi, tree roots, and creepers. Many animals inhabit the forest floor, like insects and worms.
• A Forest floor plays a crucial role in maintaining the fertility and humus content of the soil. Due to the action of microbes on the forest floor, the recycling of nutrients is ensured.

3.What Are the Causes of Deforestation?

The following are some natural causes of deforestation:

• Due to lightning strikes, dry trees and bushes can catch fire which is destructive for plants and animals living in a forest.
• Volcanic eruptions can destroy forests by causing forest fires.
• Extreme heat sometimes ignites fires too.
