Food is the basic need for man. Rice is a main food in all Eastern Asian and Southeastern Asian countries. It is said that there are 2.4 billion people to eat rice everyday throughout the world. What do you think would happen if tomorrow there was suddenly no rice to eat
The only way to solve the food shortage problem is to increase the yield of the grain crop per land area through the advancement of science and technology.

Research, listening to his music and riding his motor-bike.
