The Ecological Footprint is a measure of the "load" imposed by a given population on nature. It represents the land area necessary to sustain current levels of resource consumption and waste discharge by that population. If you are living in an industrialised country, you are probably doing some things well and some things not so well in terms of reducing your ecological impact. Seven ways that everyone can reduce their footprint include:
1. It's obvious, but we have to say it. Conserve energy. Turn off the lights when you leave a room, buy energy-efficient bulbs and appliances, turn off your TV completely, rather than leave it on standby.
2. Reduce your waste. If there are ways to recycle where you live, try and do so. If you have a garden, start a compost heap. Re-use plastic bags. Give away clothes you don't use, rather than throwing them away. There are hundreds of little things you can do.
3. Live with someone! Whether it be your partner, family, children or friends, sharing your living space means sharing your ecological impact. It will probably also increase your well-being!
4. Leave your car in the garage. Car use has a huge impact on ecological footprint. Obviously it's easier for some people than others, but where possible, try to use public transport more. Or, even better, get on a bike, or simply walk!
5. Go local. Why buy tomatoes from another country, if you can get home grown ones? For those living in Europe - think about all those miles travelled by wine from South Africa and Australia, when Europe produces some of the best wines in the world.
6. You don't have to become vegetarian, but cutting down on meat, particularly beef, and particularly from animals fed by imported soya feed, is an effective step to reducing your footprint.
7. It has to be said that air travel is one of the biggest contributors to many people's footprints. For example, flying direct from London to Sydney and back would add 5.44 g ha to your footprint - that's the average Briton's footprint for an entire year. Flights with a connection add even more polluting air miles.
