Trees are necessary for life on Earth!
Produce oxygen. Trees absorbe the carbon dioxide that humans release into the environment through pollution and purify the air.
Reduce the level of ozone. This means a reduction in temperature and more breathable air.
Reduce soil erosion. Thanks to their roots, trees prevent landslides. They also facilitate the absorption of rainfall and prevent further soil damage.
Create ecosystems for animals, insects and other plants. Trees are a fundamental part of several ecosystems. They provide home and food for many living species. Each tree is a life-safer for many critters. Planting trees means safeguarding the life of an area of our planet that would otherwise be arid and desolate.
Create work. In poor areas of the planet, tree planting provides work and vital income for local people.
