Here are some tree facts explaining why you should invest in tree planting to mitigate global warming.
- A single tree can absorb CO2 at a rate of 48 lb. (21 kg) per year. In other words, a single tree will absorb between a 1/4 to 1/2 ton of CO2 over a lifetime of about 100 years (some trees live longer).
- Trees act as natural pollution filters by absorbing pollutants through the stomates in leaf surfaces.
- Trees lower temperature by transpiring water and shading surfaces.
- Trees reduce heat sinks. Heat sinks are 2-4 degrees Celsius warmer than the surrounding area.
- Trees reduce erosion.
- An acre (0.4 hectare) of trees absorbs enough CO2 over one year to equal the amount produced by driving a car 26,000 miles (42,000 Km).
- Trees provide food and wildlife habitats.
- Planting trees remains one of the cheapest, most effective means of drawing excess CO2 from the atmosphere.
- Trees recharge ground water and sustain stream flow.
