This also reduces biodiversity. Crops are often sown, treated and harvested by machines which create pollution, and fertilisers are added to fields in larger amounts which can cause eutrophication . Intensive farming can also mean keeping livestock in smaller pens with regulated temperatures.
How does farming affect biodiversity GCSE biology?
Farmers growing arable crops often specialise in growing only one crop to maximise their profits. This is called monoculture . It can quickly reduce key nutrients in the soil and lowers biodiversity .
How can farming affect biodiversity?
Biodiversity generally decreases when the intensity of farming increases11. Farming has become ever more industrial, and farmers are tending to specialise, focusing on a few or even single high-output species or varieties.
Does farming increase biodiversity?
Increasing within-field biodiversity can be achieved through planting crop mixtures and multiple crop varieties. The establishment of diverse plantings at field margins should also be considered.

How intensive farming has affected our ecosystem?
Intensive farming can have severe impact on soil such as acidification, nitrification, desertification, decline in organic matter in soil, soil contamination (e.g., by heavy metals and agrochemicals), soil compaction, and erosion.
How does intensive farming affect the ecosystem?
These pose serious pollution risks to ground and surface water, considering that a farm with only 200 cows can produce as much nitrogen as a community of up to 10,000 people. Runoff from such farms can cause algae blooms, which can devastate freshwater, brackish, and saltwater ecosystems.
How does farming cause pollution?
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.
