Comment: (May 08) Now I am wondering this field will be a key area from now on. I wrote it in my April BLOG, the world has been shaken by oil price until now, however, I think such times might be going over sooner or later. All countries are now very serious to address to their oil demands and challege to develop renewable energy. The times is now moving on towards this direction and not only advanced countries and developing countries as well, but all other countries coming after will need foods, especially critical for less-developed countries, which is now global issue.
