How did agriculture change our life?

Modern agriculture was born just 12,000 years ago, when we began to grow wild wheat and barley in the Fertile Crescent of the Middle East and Mediterranean basin, and to tend to the first rice paddies in swamps in China. Agriculture transformed our way of life, giving us more consistent food supplies, allowing the growth of civilizations, and supporting an exponential boom in human population.

How do antibiotics affect animals?

The widespread use of antibiotics in meat production in animals that are not sick is contributing to the public health crisis of antibiotic resistance. Two-thirds of antibiotics important to human medicine in the U.S. are sold for use in livestock, not people. The regular use of these drugs in the food and water of farm animals to (poorly) help them survive the often crowded, unsanitary, and stressful conditions on CAFOs contributes to the rise and proliferation of antibiotic-resistant bacteria. These bacteria can then spread from CAFOs via air and water, including water used to irrigate crops, and can end up in animal waste used to fertilize crops. Contaminated meat and farmworkers’ clothing and shoes can also spread these antibiotic-resistant bacteria into our communities. Resistant bacteria can even “teach” other bacteria resistance, and this process can take place anywhere bacteria are found, including in our homes and guts. The exposure of workers and farm-adjacent communities is particularly high.

Why are antibiotics used in farm animals?

The regular use of these drugs in the food and water of farm animals to (poorly) help them survive the often crowded, unsanitary, and stressful conditions on CAFOs contributes to the rise and proliferation of antibiotic-resistant bacteria.

How much nitrogen did farmers use in 1964?

A big boom, indeed: In 1964 U.S. farmers applied about 4.3 million tons of nitrogen to their crops each year.
