It is thought that this unusual warming of the earth has been caused by greenhouse gases such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes. Such gases not only add to the pollution of the atmosphere, but trap the heat of the sun leading to the warming up of the planet. It has been suggested that industrialized countries would try to reduce the volume of greenhouse gas emissions and plant more trees to create 'sinks' to absorb greenhouse gases.78. The changes taking place in our climate have become
