At present, the world population is approximately 70 billion. It will be 90 billion in 2040 according to the report. The farmland is limited and the crop harvest is getting worse because of global warming.The future foods may be Cyanophats, fabricated foods and processed foods. Lately, UN recommended bugs. A worm has higher protein and 10 times more calcium than beef. The expenses for feeding the bugs are 1/12 less than that of animals. FAO suggested recipes for bug dishes for a restaurant menu. The ranking of edible bugs is a beetle first, and next, worm, bee, ant, grasshopper, cricket, spider, scorpion etc. East Asian countries such as Vietnam, China, Thailand, and Latin American countries such as Mexico and Columbia eats bugs but most of Westerncountries tend to disgust. I heard that our previous generation ate grasshoppers when I was young. In memory of those days, sometimes people eat roasted bugs as an event in the country festival. I thought that eating bugs is a story of old days when food was wanting, but now I am afraid that we are likely to have bugs as the future food due to the shortage of food. I wish that individuals and nations work together in order to make the healthy and affluent society worldwide.
