The most reasonable conclusion is that we should limit particle emissions to reduce health risks. As a consequence, the greenhouse effect would come more fully into view, which we could then hope would further strengthen the resolve to reduce emissions of CO2 and other greenhouse gases.
最合理的结论是我们应该为了降低健康风险而限制颗粒物的排放。这样的话温室效应会变得更为显著，我们希望二氧化碳和其他温室气体减排的决心会因此进一步增强。
