food self-sufficiency

Japan's food self-sufficiency ratio is one of the lowest in the world. This is almost the worst in the top developed countries. It was 73% in 1965 and since then getting only lower and now it came down to about 40%. The main factor I think is the bad condition for farmers.
After the high-growth period of the 1970s, a huge number of farmers moved to cities, and vast area of fields for farming transformed into housing and industrial land. Young manpower is in short and only older workers left. Cheaper food from Asian countries come into Japan, so that safer but expensive domestic products are not welcome really. Young people don't want to be farmers because it's not stylish. Farmers' population keep getting small.

Though Japanese people are now crazy about ECO and organic/natural products, Japan's food mileage is the world highest, adding a large amount of CO2 into the global atmosphere. People in Japan are tend to look at things only you can actually see. But some people start realizing what's underneath it. I want people to get it little deeper and think about it. Why they like organic products. Why ECO is so big now. Not only complain about the U.S. military bases in Japan, but how the food self-sufficiency affect the bases.
