South Asia has one of the most serious air pollution problems in the world. Out of the more than 6.5 million estimated global premature deaths due to air pollution, roughly one-third occur in the region. Dirty air also has major impacts on the economy, crop yields, biodiversity, and development. The scale of the problem, and the fact that air pollution does not recognize territorial boundaries, require international cooperation. No one country can do what is needed on its own.
尽管我们常将气候变化与空气污染视为两个独立的问题，但实际上二者紧密交织。从化石燃料燃烧到某些农业活动，两者的成因大量重叠，且多种污染物同时加剧全球变暖和空气污染。这两场危机还对人类健康、生态系统和经济产生叠加的有害影响。
