TREE FACTS

How Do Trees Help Us?

1. Oxygen Replenishment - Trees convert carbon dioxide and water into the oxygen we breathe.
2. Carbon Dioxide Control - Trees absorb carbon dioxide from the atmosphere.
3. Filtering of Ground Water - The roots of trees trap pollutants that would contaminate ground water.
4. Soil Retention and Rejuvenation - Tree roots hold soil in place, while dead tree leaves return nutrients to the ground.
5. Wildlife Habitats - Trees help protect the habitats of thousands of species of animals.
6. Productivity, Beauty and Health - Studies have shown that workers with views of trees are more productive and less stressed. Patients with views of trees and greenery recover faster and require less medication.
7. Climate Control - Trees are natural barriers to wind, snow, rain and solar rays.

More About Trees

1. It is estimated that there are 6 million individual trees in London and a further 65,000 'stands' of trees.
2. A whole tree is needed to supply 270 copies of an average paperback book.
3. A large beech tree can provide enough oxygen for the daily requirement of ten people.
4. Trees have a positive impact on the incidence of asthma, skin cancer and stress related illness by filtering out polluted air, reducing smog formation, shading out solar radiation and by providing an attractive, calming setting for recreation.
5. Trees strengthen neighbourhood communities by providing people with an opportunity to work together for the benefit of the local environment.
6. Trees can save up to 10% of energy consumption through their moderation of the local climate.
7. One hectare of woodland grown to maturity and looked after forever would absorb the carbon emissions of 100 average family cars driven for one year. [Climate Care/Trees for London estimate.]
