Question

about how many years ago did agriculture began

Answer 1

Around 12,000 years ago did agriculture began.The Green Revolution produced the last major improvement in food production during the latter decades of the twentieth century as new crop varieties were created by plant breeders. These new varieties depended on large inputs of fossil-fuel dependent fertilizers, irrigation, insecticides and herbicides. William Paddock warned, at the time of the beginning of the Green Revolution, that the increased agricultural productivity would simply produce more malnourished poor people if curbs were not applied to the increase in human numbers that would result from increased food availability. Global population growth since the beginning of the Green Revolution has borne out the futility of increasing food availability in the absence of measures to control human fertility..
