Did you know trees provide us with environmental services? Some of the more obvious services include shade, the control of soil erosion, nutrient cycling, food, oxygen production and the provision of shelter for wildlife.

Unfortunately little is known about the economic value of a tree. An article that appeared in the Agriculture and Fisheries bulletin estimated it would cost $664 to mechanically recreate the services that one tree provides over a 50 year period. However, our actions have a huge impact on the efficiency of these environmental services. Humans worldwide emit 7.1 billion tons of carbon dioxide annually. Furthermore, Natural sources emit an additional 150 billion tons of carbon dioxide (Co2) year on year. Trees remove 154 billion tons of carbon dioxide through the process of photosynthesis. Yet this leaves us with an oxygen deficit of 3.1 billion tons every year. Subsequently, the American Forests organisation (http:/www.amfor.org), suggests that three trees should be planted for each ton of Co2 emitted. Figure out how much carbon dioxide is produced by Bermudians.

Consider how much carbon dioxide you emit into the atmosphere. At home multiply your electricity usage bill (this is measured in Kilowatts per hour or kWh) by 1.5 pounds of carbon dioxide (Co2) for every kWh. Next calculate the amount of tons by dividing the total pounds of electricity generated (CO2) by 2000. Now imagine the amount of (Co2) produced by the other 27,000 dwelling units present in Bermuda.

Everyone has a responsibility to care for our natural environment. So plant a tree and enjoy its benefits while you simultaneously recharge the atmosphere with life giving oxygen.
