We need to continue to decrease the growth rate of the global population; the planet can't support many more people.

If everybody switched to organic farming, we couldn't support the earth's current population - maybe half.

Even as the population doubled from three to six billion, we managed to race ahead with all kinds of technological and scientific events in agriculture - from using more fertilizers to mechanization to advanced plant breeding.

India has the opportunity to be a leader in genetic engineering, It has institutions that no other country has.
