What are three options to increase food production? Discuss each giving the salient features, merits and demerits.

Three options to increase food productions are:

(a) Multiple Ovulation Embryo Transfer Technology is one way to increase food production. In this using certain hormone the production of egg is increased per cycle such that mating of one pair can give rise to many offspring together.

DEMERIT: The technology required is high level. It is costly method. The success rate is also low. Although the method give many offspring at a time but is time consuming.

(b) Tissue culture is another way that helps in the production of large number of plants within a very short span of time with just single cell. Apart from increase in yield, it also helps in the regeneration of diseased free plant.

DEMERIT: In tissue culture all the offsprings are genetically identical, hence there are chances of reduction of genetic diversity.

(c) Single cell protein is an alternative source of protein obtain from microbes. The cost of production of microbes is very less, the time taken to generate the protein is nil and the amount of protein generated is very large.

DEMERIT: Although the growth of microbes is a cheap process but their maintenance is a very costly process. Uses high technology in order to produce the medicines etc. Chances of it becoming toxic due to any infection in the microbes.
