The loss of Westwood Boulevard's large shade trees was much more than a visual loss (June 20). Before they were cut down by UCLA grounds maintenance forces, each of the mature eucalyptuses intercepted on its leaves the cancer-causing diesel particulates from trucks, buses and cars. The cooling effect of these large-specimen trees has been estimated to be the approximate equivalent of eight house-sized air conditioners running 20 hours a day.
To destroy this remarkable resource in the face of an energy shortage is to consider trees an enemy of technology. Unfortunately, other localities are also cutting major trees.
