Environmental scientists have identified three problems with relying primarily on pollution cleanup. First, it is a only bandage as long as population and consumption levels grow without corresponding improvements in pollution control technology. For example, adding catalytic converters to car exhaust systems has reduced some forms of air pollution. At the same time, increases in the number of cars and the total distance each travels have reduced the effectiveness of this cleanup approach.
環境科學家確認了依靠的三個問題主要汙染清潔。 首先,只要人口和消耗量在污染控制技術繼續增長,不用對應的改善它是唯一的療法。 例如,增加催化轉化器到汽車排氣系統減少了大氣污染的某種形式。 同時,在汽車的數量的增量和總距離其中每一個移動減少了這種清潔方法的有效率。
