How long can our civilization flourish? Will our civilization remain thousands of years hence? During the Cold War the greatest threat to humans was nuclear annihilation, but today it is the environmental problem. Many people are afraid that global warming might collapse our civilization. In 1997, COP3 adopted the Kyoto Protocol to reduce greenhouse gas emissions, but the U.S. and Australia have declined to ratify the agreement. It has turned out a failure. On this page, I analyze the problems of the Kyoto Protocol and propose an alternative feasible framework that reduces greenhouse gasses.

About one-third of the world's land surface is arid or semi-arid. The Earth's landmasses are losing 24 billion tons of topsoil and making 12 million hectares of the Earth useless for cultivation every year. The desertification is, however, not necessarily anthropogenic. So, first, we must elucidate what are the natural conditions of the desert. Then we can identify what are the artificial causes of desertification.
