    en.wikipedia.org/wiki/Tree

    Trees evolved around 370 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of the ground by the trunk, which typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to ...

    en.wikipedia.org/wiki/Deforestation_and_climate...

    Throughout their lifespan, trees continue to sequester carbon, storing atmospheric CO 2 long-term. [41] Sustainable forest management, afforestation, reforestation are therefore important contributions to climate change mitigation. An important consideration in such efforts is that forests can turn from sinks to carbon sources.

Some trees can live 1,000 years providing many services ...

  7. Deforestation - Wikipedia

    In these areas, the loss of grass due to the presence of trees and other shrubbery leads to more erosion than when trees are removed. [207] Soils are reinforced by the presence of trees, which secure the soil by binding their roots to soil bedrock. Due to deforestation, the removal of trees causes sloped lands to be more susceptible to landslides.
