Our Home Planet

          January's meeting of Pembrokeshire South East Energy Group started their New Year programme by showing the film 'Home', by Yann Arthus-Bertrand.

          The journey through time started 4.8 billion years ago and the first single celled organisms appeared 3.5 billion years ago. Since then evolution has seen the development of species many which did not survive but which have led to Homo Sapiens (latin for Wise Man).

          Water plays a crucial role it is vital to human life. It can be found in solid form (snow, ice, glaciers), gas (water vapour, mists, clouds) and liquid (rain, seas, rivers, aquifers). Most is found in saline seas and of the remaining freshwater 69% is in the form of ice. The film showed clearly that this ice is melting around the world from the mountains of the Himalayas, Alps, Chile, Africa to the ice sheets of Antarctica and Greenland. In most cases the melt waters are the source of many major rivers which sustain life. The mighty Jordan is a shadow of its former self whilst the Colorado river often fails to reach the Sea of Cortes. In order to continue meeting the huge demands for water in agriculture precious fossil aquifers are being tapped. Some of these have been collecting water over the last 10,000 years and will probable never be recharged.

          It was shown how until fairly recently man had lived in balance with nature. When oil became available a huge energy resource was released and the link between the two was broken. Fossil fuels have given the ability to extract minerals of which there is a limited supply. Agriculture has become oil powered.

          The rainforests, which are so necessary to the balance of our environment, are fast disappearing. Some of us remember when rain forests were referred to as the planet's lungs. In the Amazon cattle grazing and growing soy beans have been the main drivers whilst in Indonesia logging, growing palm oil and eucalyptus (for paper) has led to deforestation.

          The film ended with an upbeat message. The fuels we are using now have captured the energy from the sun over the millennia. That same sun is able to give us all the energy we need today. Renewable energy in the form of wind, solar, hydro is available. Many countries have taken up the challenge and are able to generate electricity from these sources. All that is needed is the will by governments to take up the challenge.

          The film proved extremely thought provoking and was followed by a discussion. It was pointed out in a recent report that to avoid a 2 percent rise in global warming 80 percent of the known fossil fuel resources need to stay in the ground. One suggestion was that all schools should show this film it is the students' future after all.
