The importance of trees
We all know that trees are vital for life on Earth - here are three of the top reasons why.
1. Global climate change warrior
Trees play an important role in diminishing the effects of natural disasters. For instance, during heavy rainfall their canopies slow down the water before it hits the ground, and the roots help the water penetrate the soil, reducing flooding and soil erosion. Furthermore, through photosynthesis, trees absorb carbon dioxide from the atmosphere, where it contributes to global warming. The carbon is pulled into the ground, where it helps create living soils by improving soil structure and making water and nutrients more available to the soil microorganisms, thereby enriching the soil microbiome.
2. Biodiversity and wildlife habitat
A large biodiversity is essential for our survival - think just about the role pollinators play in food production. Trees not only enrich soil life below ground, but also provide shelter and food for a large variety of plants and wildlife above ground, including fungi, pollinators such as insects and butterflies, birds, reptiles, and mammals. Moreover, they create wildlife corridors that help species spread across the landscape.
3. Human living environment
Not only do trees reduce air pollution, quieten noise and keep our cities shaded and cool - spending time in nature is also proven to promote our physical and mental well-being. Trees also provide fruits, nuts and timber that help support human livelihoods, and have been shown to strengthen communities and social connections.
