Abstract
The global carbon recycling system related with soil ecology is not well understood, and the plankton ecosystem variation in the ocean surface with the CO2 dissolution should be studied in relation to its effect on the fishery resource. Also, the risk assessment on the ecosystem will be important for the CO2 sequestration. And, it is another important thing that the human being social-life should be made depend on the solar energy, which would be related to the ecoengineering. These subjects should be totally discussed from the view point of the eco-engineering to minimize the uncertainty on the global warming. “Withdraw from carbon society” is an important keyword for the post Kyoto Protocol, but it is preferable to think a wider system of global environment remediation with the core of “withdraw from carbon society.” In this sense, the role of the Society of Eco-engineering in the global environment remediation is considered to become more important from now.
