Our Ecological Footprints Are Growing

Supplying people with renewable resources and dealing with the resulting wastes and pollution can have a large environmental impact. We can think of it as an ecological footprint-the amount of biologically productive land and water needed to supply the people in a particular country or area with renewable resources and to absorb and recycle the wastes and pollution produced by resource use. The per capita ecological footprint is the average ecological footprint of an individual in a given country or area.

我們的生態足跡發展

供應人與可再生資源和處理產生的廢物與汙染構成一個很大的環境影響，我們可以把它看做為一個生態足跡。生物生產所需的土地和水供應人在一個特定的國家或區域得可再生資源，吸收並且回收資源和汙染導致的廢物。人均生態足跡是一個個體的平均生態足跡在一個特定的國家或區域。
