Let's do this. Have you ever heard of a solar stove? It's a small, sun-driven metal or foil lined contraption, some with a glass lens, that can cleanly cook or boil water just from the sun's rays.
It can help replace the burning of scarce firewood, coal, and dung -- which as heating sources all also pollute rather badly. Many organizations are trying to distribute these. Take note, and help when you can.
"...Methane comes from landfills, farms, drilling for natural gas, and coal mining. Soot, called black carbon by scientists, is a byproduct of burning and is a big problem with cook stoves using wood, dung and coal in developing countries and in some diesel fuels worldwide..."
