Do you think Biology can help in further increasing the yield of food? If so, how?

Yes, Biology can help in further increasing the yield of food. New varieties of plants and new breeds of cattle, poultry, etc. are being developed with the knowledge of Biology. The science has also increased our knowledge of diseases of plants and animals, and how to cure them. Plants and animals of newer varieties are cultivated by cross-breeding through the application of biotechnological principles, unleashing unexplored concepts for a brighter future. All these efforts are helping us to produce more food in fields, dairies and poultry farms.
