Answer 1

Answer:

Farms have changed a lot in the last 50 years. Farms are bigger, livestock are usually raised inside, yields are higher, less manual labor is needed, and it's not common to see dairy cows, beef cattle, pigs, and poultry on the same farm

From complete reliance on animal power in 1900, farmers rapidly embraced mechanical power (see box, “Mechanization”). Tractors had essentially replaced animal power by 1970, and mechanical harvesting of crops (sugar beets, cotton, and tomatoes, for example) became routine by the late 1960s.

50 years of change mean farmers can produce more food and fiber on fewer acres and with fewer nutrient inputs. With 50 years of change farmers can now produce more food and fiber on fewer acres and with fewer nutrient inputs.
