I subscribe to the notion promoted by Brian Swimme and Thomas Berry in the Book “the universe story” where they state that “The well being of the eco system of the planet is a prior condition for the well being of humans. We cannot have well being on a sick planet, not even with our medical science. So long as we continue to generate more toxins than the planet can absorb and transform, the members of the earth community will become ill”. Planting trees is one of the best ways we can ensure a healthy planet for good human health and well being.
In light of high temperatures resulting from global warming, trees have the ability to regulate local temperatures by transpiring water into the lower atmosphere and shading surfaces. By so doing, trees help to reduce the intensity of heat waves thereby reducing the effects of heat waves on the elderly and people with respiratory and cardiovascular disorders. The temperature regulation ability of trees helps reduce the demand on air conditioning in homes and offices thereby reducing pressure on fossil fuel burning for energy. This can be very helpful in Zimbabwe where energy shortages are acute and a significant percentage of our energy comes from coal.
