How does agriculture and industry cause water pollution

image

Agriculture intensification is often accompanied by increased soil erosion, salinity and sediment loads in water and by the excessive use (or misuse) of agricultural inputs (e.g. fertilizers) to increase productivity. Pollution caused by agriculture can contaminate water, food, fodder, farms, the natural environment and the atmosphere.

The most prevalent source of agricultural water pollution is soil that is washed off fields. Rain water carries soil particles (sediment) and dumps them into nearby lakes or streams. Too much sediment can cloud the water, reducing the amount of sunlight that reaches aquatic plants.

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 does the dairy industry affect the ecosystem?

The dairy industry is producing unsustainable amounts of untreated manure that seeps into the groundwater, threatening the livelihood of millions of people, eradicating entire ecosystems, and deepening the divide between the industry and its critics.


Why is the soil on farms loose?

Due to the deforestation that farming requires, the soil on often farms is loose and prone to weather erosion that leads to large amounts of earth sliding into nearby rivers. The dirt and other pieces of earth muddy the water and collect on the river bed, killing plants and ecosystems that thrive there.


What are the nutrients that dairy farms produce?

The most harmful nutrients produced by dairy farming are nitrates and phosphorus. Both are found in cow urine and manure and enters water sources through manure or when the cows are grazing. High nitrate contents in water can stimulate toxic algal blooms, where large clouds of algae grow over rivers, absorbing all the oxygen in the water and suffocating the life that dwells beneath.#N#Furthermore, a certain level of nitrates in water can have devastating consequences for human health, including blue baby syndrome, a condition fatal for infants. The EU recently reported that around 85 percent of dairy farms across the continent had unacceptable nitrate levels in their groundwater.


Why are dairy cows lame?

Lameness is caused by bacterial infections in the hoof “such as hoof lesions, sole ulcers, laminitis, and digital dermatitis.”.
