Step-by-step explanation:
An agricultural revolution is when farming techniques drastically improve within a relatively short period of time. This leads to a greater production of food. Three agricultural revolutions have taken place in human history. The First Agricultural Revolution, or the Neolithic Revolution, began around 10,000 B.C. Humans shifted from being hunter-gathers to being subsistence farmers and herders. The Second Agricultural Revolution, or the British Agricultural Revolution, began around 300 years ago during the 18th century. Major changes to farming techniques included selectively breeding livestock and systematic crop rotation. The Third Agricultural Revolution, or the Green Revolution, took place during the 1940s, 50s, and 60s. Improvements to plant technology allowed for much greater crop yields.
