• Trees absorb carbon dioxide and manufacture oxygen
• A single tree will absorb approximately 14.5kg of carbon dioxide each year or one ton during its lifetime
• They reduce the greenhouse effect and slow the impact of global warming
• They combat soil erosion and landslides
• Trees improve water quality by filtering pesticides and unwanted nutrients
• They help to enrich soil quality by converting nitrogen to nitrates
• The net cooling effect of a young, healthy tree is equivalent to ten room-size air conditioners operating 20 hours a day
