Planting a tree will therefore make a contribution, however small, towards fighting the greenhouse effect. It is estimated that each mature tree consumes approximately 13lbs of carbon dioxide per year on average. Urban trees consume it at a rate of about 15 times that of rural trees. Trees and human and animal life live in synergy. We require oxygen and release carbon dioxide.
Trees require carbon dioxide and release oxygen.
To maintain the environmental quality of our towns and countryside we need to plant more trees to replace those lost through old age, urban development and changes in agricultural practices. The following suggestions show how trees can be properly planted and maintained in order to grow into healthy specimens. Suitable sites for tree planting include open spaces in housing areas, land around car parks, churches, schools, supermarkets, factories, town dumps and eyesores, and along streets and roads. Once a site has been selected for tree planting, the most suitable species for planting on it must be chosen. The suitability of different species for the use and size of the site - there must be enough space for trees to develop without pruning.
