Question

why we call forests are lungs of the earth? ​

Answer 1

ANSWER

• Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. ... Carbon dioxide increases each year as a result of burning fossil fuels and deforestation.

FORESTS

• A forest is a complex ecological system in which trees are the dominant life-form. A forest is nature's most efficient ecosystem, with a high rate of photosynthesis affecting both plant and animal systems in a series of complex organic relationships.

LUNGS

• The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). ... In the alveoli, oxygen from the air is absorbed into the blood. Carbon dioxide, a waste product of metabolism, travels from the blood to the alveoli, where it can be exhaled.

Answer 2

Forests are known as the earth's lungs because they absorb a huge quantity of carbon dioxide from the atmosphere. They work, therefore conserving those lungs is critical if we are to conserve plant biodiversity and combat global warming.

• Because they provide a source of oxygen in the atmosphere, forests are referred to as nature's lungs.
• Photosynthesis is a mechanism through which plants release oxygen.
• Plants aid in the provision of oxygen to mammals for breathing.
• They also keep the atmosphere's oxygen and carbon dioxide levels balanced. Forests are known as "green lungs" for this reason.
