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.

我們的生態足跡的增長
供應人與可再生資源和處理由此產生的廢物與污染構成一個很大環境影響。我們可以把它作為一個生態足跡——生物生產所需的土地和水的供應在某一特定國家或地區的可再生資源，並吸收和回收的廢物和污染所產生的資源利用。人均生態足跡的平均生態足跡個人在某一國家或地區。
