The modern civilization that originated from the Industrial Revolution is now spreading throughout the world. The demand for natural resources is rapidly increasing and the environmental problems are getting globally more and more serious. Our civilization seems hardly sustainable. What should we do to make it sustainable? This series establishes the fundamental theory of civilization, analyzes the problems of resources and the environment in terms of entropy, and suggests a solution to them.

As Our Common Future insisted in 1987, “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Since the Industrial Revolution, human development has accelerated so much that its sustainability has come into question. Here I would like to present my proposal for what we should do to make our civilization sustainable. There are three major problems, namely the restriction of population growth, the maintenance and restoration of vegetation, and the utilization of renewable energy.

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.

Fuel cells were invented in the 19th century, but their practical application has been extremely limited to date, as thermal power generation has become the mainstream method of power generation. Today, with decarbonization and the hydrogen economy, fuel cells are again attracting attention as a method of power generation using hydrogen. Innovations are necessary for fuel cells to become more practical than they are today, not only in the fuel cells themselves but also in the way of storing and transporting their fuel, as well as in the method of producing it.

One of the most popular environmental problems is the global warming caused by the greenhouse effect, though most of the people are not sure what bad effect it will have on us.
