A build up of C02 in the atmosphere acts like glass in a greenhouse, and stops heat escaping into space. As a result the world gets hotter and climate patterns change with increasing risk of drought and flooding. This is known as global warming. CO2 is mostly produced through the burning of coal, oil and gas to produce energy including electricity. By using energy more efficiently in our homes we can held reduce the build-up of C02 in the atmosphere.
Every home produces about a ton of domestic waste a year.
About half of it could usefully be recycled. This would be good for the environment and the economy. Recycling reduces use of raw materials, lowers energy costs, and means less waste going into rubbish tips. Food can be recycled into compost for your garden. Many areas now have collection points for glass, paper, metals and other materials either at supermarket car parks or local authority landfill sites.
