Before humans started farming, we were hunter-gatherers and the world population was only four million. In different parts of the world, all at the around the same time, our ancestors worked out how to grow cereals like rice, corn, wheat, and barley. It was the birth of crop production.
Of course, different crops are suited to different environments. In Central America, squash, maize, and beans were all groundbreakers while in South America it was the potato that proved most popular. Much further south, in the grasslands of Botswana, farmers go to much greater lengths to protect their crops. But then the crops here are being ravaged not by scores of hungry baboons, but by millions of red-billed quelea, the most abundant wild bird on the planet. Faced with this winged plague, Botswanan bomb squads follow the enormous flocks to their roosts and lay explosives under their nests. Come dawn, there is nothing left but death and destruction as hundreds of trees, tens of thousands of nests, and hundreds of thousands of dead birds litter the quiet grasslands.
Despite the best attempts of the local wildlife to share in our bounty, humans have been incredibly successful as crop producers. Since crop production usually allows people to plan ahead, settle into villages, have larger families, and create more complex societies, then the biggest mark of our success as crop growers is – paradoxically perhaps - just how many of us now live in cities…
I think this article is readable and acceptable for less educated people.
This article is brought us that the history of the crop growing ,the farm is less and less than before , we should pay more attention on it .
