Concept:The balance of nature is the stable state in which living organisms and their environment support one another.
Explanation:Afforestation is the act of planting trees in an area that previously had no forest cover.
Trees take in carbon dioxide and give out oxygen, which helps keep the air clean and safe.
They also hold the soil in place, support the water cycle, and create homes for animals and plants.
These actions help to restore and maintain the natural balance of the environment.
Pollution harms nature by adding dangerous substances to the air, water, and land.
Deforestation destroys forests and reduces the amount of oxygen released into the atmosphere.
Mining removes vegetation and damages the soil and water sources around it.
These activities all disturb the balance of nature instead of preserving it.
