地理一段翻譯

Environmental scientists have identified three problems with relying primarily on pollution cleanup. First, it is only a temporary 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.
環境學家認為三種問題與主要依賴污染物清除一致。首先，這只是一個暫時繃帶控制技術，只要人口和消費水準上升而沒有在污染的相應下改進。例如，給汽車排氣系統添加廢氣淨化器可以降低空氣污染的一些方法。同時，增加汽車數量並且減少旅行的總距離和這次清除的效力接近。
