Machines help in to fight scarcity of food and hunger in a world population because machines make working easier. Various machines process food faster making it readily available thus fighting against hunger and food shortage.
machines have enabled growers to plant, maintain, and harvest larger areas of land than would have been possible without them.humans tire,machines can keep going. just in preperation alone,a machine against a man with his plow animal can make much more land ready for planting.once this area has been planted, the crop must be maintained as it grows until harvesting becomes necessary. this can all be done with machines and to the benefit of all,this often means higher per acre yield than in the past.of course better seed stock and hardier food plants contribute greatly as well. genetically engineered plants have lab machines in the process of development.this space doesn't allow for any in depth description so suffice to say;machines can endure heat,long working hours,and cooler days than a human can all through the process of food growth.
