The benefits of planting trees for our health and our planet

In a nutshell...

Trees help clean the air we breathe, filter the water we drink, soak up harmful pollutants and reduce flooding. Trees are a key ingredient in a quarter of all medicines, provide habitat to over 80% of the world's biodiversity and jobs to over 1.6 billion people.

the six pillars that explain why trees are so vital


Trees clean our air and water which leads to fewer lung and heart-related hospital admissions. Asthma rates fall among children who have more trees in their neighbourhood. Trees are used to produce medicines, reduce stress and noise, and protect us from the ever increasing harshness of the sun's rays. We're also more likely to go outside and exercise if there are beautiful trees and green spaces outside.


The leaves and bark of trees soak up harmful pollutants and release clean oxygen for us to breathe. This is more vital than ever considering that 8 in 10 of us live in built up towns and cities where a range of pollutants and toxins are emitted by everyday activities. In a single season, one mature leafy tree can release enough oxygen to sustain ten people.


The roots and leaves of trees play an important role in capturing rainwater and reducing the risk of landslides and floods. A single leafy mature tree can capture 450 litres of water through its roots every day. This is particularly important in towns and cities where the widespread use of impermeable materials like tarmac and concrete can lead to flash floods after a sudden downpour. 


From aardvarks to zebra butterflies, trees provide a habitat and shelter for woodland creatures and plants. Since 80% of the world's documented species live in tropical rainforests, deforestation puts at risk a majority of the earth's biodiversity.


Trees soak up and store carbon dioxide and other greenhouse gases and help to keep our planet cool. By planting trees we can help to mitigate the effect of climate change. Deforestation and fossil fuel combustion lead to increased levels of carbon dioxide which traps heat in the atmosphere.


Forests provide jobs for more than 1.6 million people on this planet! Sustainable tree farming provides timber and shelter and helps protect natural vegetables. Trees also supply fruits and nuts which are healthy for our bodies.
