In the stone age, humans were scavengers. They got their food through gathering berries and nuts or through hunting. After a while, though, they learned how to plant seeds and grow crops. It drastically changed how humans got food and it helped the population grow and become more prosperous. It made them more civilized and helped them go from moving to settled. The first crops grown by humans were wheat and corn. This era where humans began to farm through manual labor is called the first Agricultural Revolution.
The second agricultural revolution happened in the 1700s. This was when people moved from manual labor to machines, making contraptions that allowed for less people and more lend- Extensive agriculture. This way, crops could be grown significantly faster, and it increased urbanization. People began to move to the city due to easier access to foods.
Seed drill- invented in 1701
In modern times, starting in the 1900s, we started using gas to power our farming equipment. We began using chemical fertilizers, instead of using manure. People started to use genetic modification on their produce, to make them grow bigger and faster. This of course increased the distribution of food incredibly and turned even more people away from farming, now that they had factories and machines to do the work for them.
GMOS are Genetically Modified Organisms. They are used to change the growth, behavior, size, etc of any organism. Farmers use it to make their chickens and crops grow bigger at a much faster rate. This makes food much easier to produce and feed to the world, and it makes food resistant to pesticides. But it has some downsides. GMOs can have underlying cancer cells that potentially could affect people, and it can make some foods antibiotic-resistant. This means that they can infect people who eat those foods, and these infections kill at least 23,000 people a year.
