Development and technology that serves the “modern way of life” has largely been fuelled by the burning of coal and oil and other fossilised stores of energy. When burning these fuels, emissions are released into the air. These gases surround the earth’s atmosphere like a blanket, trapping too much of the sun’s heat. This process is causing the phenomenon known as global warming, also referred to as the greenhouse or hothouse effect. Because this heating actually causes a variety of unpredictable changes in the delicate balance of the world’s climate systems, we call this process “climate change”. Climatic changes can have potential disastrous effects on the balance of our ecosystems. To avoid this, we need to shift from a fossil-fuel intense economy to a cleaner future based on energy efficient technologies and renewable energies.
