In one year, an acre of trees can absorb as much carbon as is produced by a car driven up to 14 000 kilometres.

Two mature trees provide enough oxygen for a family of four.

Trees are the longest living and largest living organisms on Earth.

One person causes about 10 tons of carbon dioxide to be emitted a year. One tree removes about 1 ton of CO2 per year. Planting 30 trees per person will remove that person's carbon debt for the year.
