For 1st Paragraph:
Humans are able to alter the amount of food that we produce. One example of this is how humans were able to utilise four factors that enabled food production to increase during the Green Revolution. These factors are changing the system, science and innovation, increasing area of production and agribusinesses. Changing the system include the irrigation of crops, the use of fertilisers to increase the growth rate. Science and innovation increase productivity as they are used in many aspects of farming such as turning the soil, cropping and watering, etc. Increasing the area of production allows multiple crops to be farmed at once comfortably. Agriculture is the final factor. The use of machinery, fertilisers and scientific technology instead of manual farming methods increases the amount of productivity. These four factors lead to a dramatic increase in food production during the 1940s; therefore, there is no doubt that artificial alterations to farming will be able to assist the future population to the extent that it will be food secure.
