peacefully reducing our numbers would go a long way to solving the problem as well. Over population is the root of the problem. But it is also the most difficult of our puzzles to solve. You know what the best solution to high population rates is? Helping a nation become a democratic, highly technical, society... The highest birth rates on the planet all exist in under-developed countries. There is, of course, a good reason for this.. Children as "cheap" labor, and if you have enough of them in your economically deprived family, they are a great retirement plan. But look at the plight of the Western world.. Europe, Japan, the US.. all faces declining birth rates in their core ethnicities (immigrants are having more child). Were it not for US immigration policies, our own population would be in decline as is the case with Japan. As for Pebble Bed nuclear technology, it's a pretty interesting system.. and considered extremely safe. en.wikipedia.org Hawk

Wikipedia sez: A pebble bed power plant combines a gas-cooled core[6] and a novel packaging of the fuel that dramatically reduces complexity while improving safety.[7]. The uranium, thorium or plutonium nuclear fuels are in the form of a ceramic (usually oxides or carbides) contained within spherical pebbles made of pyrolytic graphite, which acts as the primary neutron moderator. Each sphere is effectively a complete "mini-reactor", containing all of the parts that would normally be separate components of a conventional reactor. Simply piling enough of the fuel spheres together will eventually reach criticality.
