Nature's contributions to people


Trees play a crucial role to maintain clean air and improve human health. Living close to trees makes human beings healthier and happier. However, human activities are leading to destruction of natural vegetation.

As human population and human consumption are increasing, we need more lands to grow food, and build cities and roads. To fulfill our needs, we are cutting down trees and destroying forests. We are cutting down trees to derive raw materials for our industries and are converting forests to farms. It is estimated that about 10 million square km of forest have been lost since the beginning of the 20th century. Deforestation has negatively impacted our environment and health as it reduces the potential to absorb carbon dioxide and other pollutants from the atmosphere.

To protect forests, we need to address the root causes of deforestation. We need to reduce our consumption and find sustainable ways of growing our foods, building our cities and manufacturing products. Forests can also be restored, through planting trees in cleared areas or simply allowing the forest ecosystem to regenerate over time.

In urban areas where air pollution tends to be worse, we should find ways to protect existing trees and plant more trees.

We should create more green spaces by creating parks, lining roads with trees and creating urban forests. By planting different variety of trees, we can attract, bees, birds and small insects that help to maintain healthy ecosystem.

Such green spaces reduce global warming, reduce air pollution, reduce urban heat, and provide attractive and calming setting for living and recreation.

Trees are like
giant air purifiers.
Let's save them!
