The second, and related, problem is that some of the asset classes were quite small.

Indoor air pollution (IAP) is an excellent example: A massive global problem and the second-largest driver of global warming, IAP causes over 3.5 million needless deaths each year, mainly in the developing world, and has a disproportionate impact on women and children.
