Agricultural pollution has many different sources. Nitrogen-based fertilizers produce potent greenhouse gases and can overload waterways with dangerous pollutants; chemical pesticides with varying toxicological effects can contaminate our air and water or reside directly on our food.


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. By 2007, American farmers were dropping 5 .7 million tons of nitrogen fertilizer just on corn. Synthetic forms of nitrogen are different in some key ways from the nitrogen occurring naturally in our atmosphere.


How are farm workers exposed to pesticides?

Farmworkers are particularly susceptible to exposure, coming into contact with pesticides when spraying fields, inhaling pesticide “drift,” and exposing their families via contamination on their clothing. Rural residents in general may be exposed to contaminated water, air, and food.


How does algae overgrowth affect the ecosystem?

As algae then die off, aerobic bacteria decompose them, consuming oxygen in the process and starving other marine life. Algae overgrowth can also block sunlight, disrupting the ecosystem below that relies on the sun for energy.


How does agriculture contribute to pollution?

Agricultural pollution may be triggered by certain farming activities that tend to damage, contaminate, and degrade the environment and ecosystem. A source of pollution in farming is the burning of waste materials from agricultural activities such as land clearance, applying excessive fertilizer more than the plants’ requirement, and use of certain pest control chemicals that are nonbiodegradable. The aftermath of these processes includes the introduction of certain chemical substances into the food web, generation of smoke and PM, and destabilization of habitats. Furthermore, nitrates from agricultural processes are known chemical pollutants in groundwater aquifers. Eutrophication that occurs due to excess nutrients in water bodies is commonly related to fertilizers that are applied at a higher dose than they are required for the plants’ uptake. Excess nitrogen and phosphates can leach into surface water or groundwater through runoffs.


What is the role of agriculture in the economy?

21.3.3 Agricultural activities. Agriculture serves as a source of economic development for any country and sustains the livelihoods of the populace. Despite these important roles of agriculture, pollution still emanates from agricultural activities resulting in a number of health and environmental risks.


What is agricultural pollution?

Agricultural pollution is the pollution of the ecosystem and the related environment as a result of the utilization of natural and chemical products for farming. This contamination is actually harmful to all living organisms that depend on food for farming.


Causes of agricultural pollution

Chemical fertilizers: These are mostly nitrogen and phosphorus-based chemicals such as ammonia and nitrates that promote soil fertility in the right amounts. But in most cases, they are used in excess of the requirement and are therefore retained in the soil without increasing its goodness.


Types of Agricultural Pollution

Why was agriculture bad for humans?

Besides malnutrition, starvation, and epidemic diseases, farming helped bring another curse upon humanity: deep class divisions. Hunter-gatherers have little or no stored food, and no concentrated food sources, like an orchard or a herd of cows: they live off the wild plants and animals they obtain each day.


What were the negative effects of the agricultural revolution?

Another negative that came from the Agricultural Revolution was the necessary conditions needed for efficient farming, such as; adequate farm buildings, access of roads, drainage of wetlands, transport facilities for marketing, and sources of finance for farmers.


What are the impacts of agriculture to the society?

The result is that agriculture globally exerts increasing pressure on the land and water resources of the earth, which often results in land degradation (such as soil erosion and salinization), and eutrophication. Agriculture is also associated with greenhouse gas emissions (Kirchmann and Thorvaldsson 2000).


How did farming change world population?

Farming increased the yield of food plants and allowed people to have food available year round. Animals were domesticated to provide meat. With agriculture, people could settle down, so that they no longer needed to carry all their possessions (Figure below).


Why is it so hard to meet the demand for accelerated agricultural productivity?

The reasons for this have to do with ecological factors. Global climate change is destabilizing many of the natural processes that make modern agriculture possible.


How do cattle damage soil?

Cattle and other large grazing animals can even damage soil by trampling on it. Bare, compacted land can bring about soil erosion and destruction of topsoil quality due to the runoff of nutrients. These and other impacts can destabilize a variety of fragile ecosystems and wildlife habitats. Chemical Fertilizer.


What is the effect of nitrogen on soil?

In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.

Irrigation has also been connected to the erosion of coastlines and other kinds of long-term ecological and habitat destruction. A huge amount of agricultural territory is used primarily as pasture for cattle and other livestock.


What causes algae blooms in China?

Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive.


What are the consequences of irrigation?

One of the most obvious consequences is the depletion of aquifers, river systems, and downstream ground water. However, there are a number of other negative effects related to irrigation.


How can humans limit agricultural runoff?

That said, humans can limit agricultural runoff by being careful not to over-water their crops and avoiding excessive pesticide use. Many farms have switched to drip irrigation to conserve water.


What happens when water from rain, melted snow, or irrigation doesn’t sink into the soil?

Runoff happens when the water from rain, melted snow or irrigation doesn’t sink into the soil for proper absorption. Instead, it moves over the ground, picking up natural and artificial pollutants along the way. Eventually, those contaminants get deposited into coastal waterways, lakes, rivers and even underground sources of drinking water.


What is the leading source of impairments to surveyed rivers and lakes?

The U.S. Environmental Protection Agency (EPA) says this runoff is the leading source of impairments to surveyed rivers and lakes. Complicating matters is the fact that there’s no single source of this kind of runoff — farmers can’t just make one change to solve the problem.


Why do farmers use drip irrigation?

Many farms have switched to drip irrigation to conserve water. It gives water directly to a plant’s root rather than the entire surrounding area. This change is one example of a relatively simple choice that could cut down on unnecessary water usage and prevent agricultural runoff.


Why are charter boats staying on the shore?

In the summer of 2019, charter boats stayed on the shore because no one wanted to go fishing. Some waterfront restaurants shut down, and people canceled their vacations after getting word of the stench associated with the algae. People are eager to find a solution to reduce the impact of the red tide algae.


Why is water a resource?

Water is a resource that gets a lot of coverage, probably because living things need it to survive. You may not think much about your water sources, especially if getting hydrated is as easy as turning on the tap and filling up a cup.


Is there a way to solve the problem of rain?

There’s no easy, straightforward way to solve the problem, especially because some things out of human control, such as heavier rainfall, can make it worse. However, the more humans can do to minimize the issue — by being more mindful of techniques like irrigation and pesticide use, for example — the better.
