Tr e e C a n a d a Tr e e v i a Trees reduce the effects of global cycling – 12 trees will, over their lives, absorb almost 2 tonnes (metric tons) of carbon, the same amount of carbon produced by an SUV going 20,000 km. Trees conserve energy by reducing heating and cooling costs by up to 50%. Trees act as the “lungs of the earth” by absorbing carbon dioxide, carbon monoxide, sulfur dioxide, ozone and other atmospheric pollutants.
Trees give people a psychological boost – studies show that they make us feel good! Trees can increase property values by 20%, help instill civic pride and boost tourism. Trees give wildlife (mammals and birds), a place to live. Trees reduce water run-off and keep streams clean – one large tree can lift 378 liters (100 gallons) of water out of the ground and discharge it into the air each day.
