A Greener Life. A Better Life
Trees are the longest living organisms on the planet and one of the earth's greatest natural resources.
  • By cooling the air and ground around them, the shade from trees helps cool the Earth's temperature.
  • Trees lower air temperature by evaporating water in their leaves.
  • Trees are good noise barriers, making a city and neighborhood quieter.
  • Trees help prevent city flooding by catching raindrops and offsetting runoff caused by buildings and parking lots.
  • A tree-line buffer between fields and streams helps remove farming pollutants before they reach the water.
  • Tree roots stabilise the soil and prevent erosion.
  • Trees improve water quality by slowing and filtering rain water as well as protecting aquifers and watersheds.
  • Trees provide protection from downward fall of rain, sleet, and hail as well as reduce storm run-off and the possibility of flooding.
  • Trees provide food and shelter for wildlife.
  • Trees located along streets act as a glare and reflection control.
  • Trees enhance the aesthetics of our environment. Their grandeur, tenacity, and beauty are probably the most enjoyable aspect of trees.
A Greener Earth. A Fresh Life
  • Trees renew our air supply by absorbing carbon dioxide and producing oxygen.
  • A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four!
  • Trees help reduce the "greenhouse effect" by absorbing carbon dioxide.
  • The amount of oxygen produced by an acre of trees per year equals the amount consumed by 18 people annually. One tree produces nearly 260 pounds of oxygen each year.
  • One person causes about 10 tons of carbon dioxide to be emitted a year. One tree removes about 1 ton of carbon dioxide per year.
  • One tree can absorb as much carbon in a year as a car produces while driving 26,000 miles.
  • An average tree absorbs 4.5 kg of air pollutants every year.
  • Planting 30 trees per person will remove each that person's carbon debt for the year.
A Greener Earth. A Cost Efficient Way of Life:
  • In 50 years one tree recycles more than $37,000 worth of water, provides $31,000 worth of erosion control, $62,000 worth of air pollution control, and produces $37,000 worth of oxygen.
  • The shade and wind buffering provided by trees reduces annual heating and cooling costs by 2.1 billion dollars.
  • Each average-sized tree provides an estimated $7 savings in annual environmental benefits, including energy conservation and reduced pollution.
  • Well placed trees help cut energy costs and consumption by decreasing air conditioning costs 10-50% & reducing heating costs as much as 4-22%.
  • Shade trees can make buildings up to 20 degrees cooler in the summer.
  • The energy saved from recycling one glass bottle is enough to power a light bulb for four hours.
  • Recycling one plastic bottle can save the same amount of energy needed to power a 60-watt light bulb for six hours.
