We take for granted that our local environment can interact with the rest of the world.
– we can transport our rubbish somewhere to dump it.
– we can bring in food and materials.
– our air and water can be replenished by the wind and the rain.
Most communities are also dependant on a faraway source of energy and resources such as electricity, gas, coal or wood. It is surprising how much land we require to survive. A typical city may need an area 20 times its size! It has been calculated that a person in the UK requires, on average, 4 hectares of land. Over 6 hectares are required to support the typical lifestyle of a North American. However, if we consider that the equal distribution of the Earth’s productive land among its present inhabitants would allot each of us 1.5 hectares, it becomes obvious that we need more than one planet if everyone lives as we do! Now it is your turn to calculate how many hectares that you require to live!
