Agriculture, the cultivation of food and goods through farming, produces the vast majority of the world’s food supply. It is thought to have been practiced sporadically for the past 13,000 years,1 and widely established for only 7,000 years.2 In the long view of human history, this is just a flash in the pan compared to the nearly 200,000 years our ancestors spent gathering, hunting, and scavenging in the wild. During its brief history, agriculture has radically transformed human societies and fueled a global population that has grown from 4 million to 7 billion since 10,000 BCE, and is still growing.3
The road to the present has not been smooth. Resource degradation, rapid population growth, disease, changing climates, and other forces have periodically crippled food supplies, with the poor bearing the brunt of famine. We still face many of the same challenges as our ancestors, in addition to new and even greater threats. To successfully navigate an uncertain future, we can begin by learning from the past.
Lines AB and CD intersect at E for A (2,4),B (0,2), C (3,0), and D (3,3) on a coordinate plane. Point F is coplanar with these points, but not collinear with AB or CD.
