The First Agricultural Revolution, known as the Neolithic Revolution, was the transformation from hunting and gathering, to farming. People began planting seeds this grew the same plant as word spread more people began using this tactic. This happened between 10,000 BC and 2000 BC. Wheat, barley, rice and peas. Where some of the first domesticated plants ever found. farming made humans produce more food and became more healthy.
The Second Agricultural Revolution shifted agriculture from reliance on the sun to fossil fuel. This period saw the development of new farming machinery. this happened in between 1700-1800. These machines made farming faster, easier and more effective in the past each acre of corn could feed 8 people now they can feed around 125.
The biotechnological phase (3rd revolution) began with chemical farming. using herbicides, pesticides, and fungicides, this kept the crops healthy and increased the amount of food produced.This revolution started from 1870-1980. This also produced GMOs (Genetically modified organisms) that can have traits of other plants, like corn being weather resistant, or making more cobs. But GMOs have been around for centuries wheat used to be wild grass and now it's the most popular crop besides corn.
This shows a food (tomato) that has grown in size to accommodate the population (This is an example of a gmo)
GMOs are genetically modified organisms they are just as the name entails they are crops or animals that have been modified to fit criteria. GMOs can heavily help the food business making even live animals like chickens grow in 3/4 the time and 30% bigger. pros that make farming more efficient and cons the can be bad for the environment.
