Trees are vital in combating climate change by absorbing carbon dioxide (CO2) during photosynthesis and storing it in their trunks, roots, and branches. Forests help absorb around 30% of global carbon emissions each year. Trees also support biodiversity by providing habitats for wildlife and maintaining ecosystem balance. Planting trees and protecting forests are simple yet effective actions to reduce greenhouse gases, prevent soil erosion, and improve air quality. Urban trees help cool cities and improve mental well-being. To fight climate change, it's essential to conserve forests and expand tree planting efforts.
