Question

Due to the limitation of land and water resources on planet earth, biotechnology can help to increase the crop yields to meet human needs and demands in the years to come. farmers have to produce ________% more grain per hectare to feed human population in ________.

Answer 1

Biotechnology helps increase the crop yields to meet human needs and demands in the years to come. Assuming that the production of crops today, March 2017 is 10 million tons and the demand for crops is determined using the given population which is 7 billion. If an average person needs 10 kg of food daily, the needed food is a total of 70 million tons. The current supply is 10 million tons per day, so a balance of 60 million tons per day is still needed. Therefore, farmers have to produce 85.71% more grain to feed human population in 2018.
