A solar-powered lamp that costs $25 can pay for itself in fuel savings in under two months.

Evans Wadongo is doing a great job as an individual alone. But he has only distributed 50,000 solar lamps in Kenya in 10 years. At this rate it would take millennia to reach the people that need them in Kenya alone.

If the world were on a war footing to save itself from the danger of global heating, it could easily have provided them to billions of people by now.

The BRIC Nations' Response to [global heating] Is Critical to the Fate of the Planet.

Reducing pollution and environmental degradation in India is a big challenge combined with reducing poverty.

The comparison between India and China is partly misleading. Large parts of China are deserts, and the size of "China" probably includes Tibet.

Nonetheless, India is clearly overpopulated. The article has a blind spot in treating population and population growth as beyond control. Population growth is not a natural phenomenon; it is the result of failure to make birth control and abortion easily available to women.

India's law against sex-selective abortion, to the extent that it is enforced, promotes future population growth. It will be limited by the number of women; men that don't have children won't contribute. Thus, parents that choose to have boys rather than girls will reduce the size of future generations. We should not discourage them from helping to reduce the pressure on one side of the vice.

If you want to feed birds, take care that your feeder doesn't encourage introduced species at the expense of native species.
