Transcript of Negative Effects From Commercial Farming

By: Alyanna, Emily, And Kelly Call to action Introduction Water Quality Soil Erosion Climate Change Commercial agriculture is the large-scale production of crops for sale. It is made to distribute to markets to sell. In commercial farming crops such as wheat, tea, coffee, sugarcane, cashew, rubber, banana, and cotton are harvested and sold into world markets. Commercial agriculture also includes the raising of farm animals to use their body parts for food sold into the market. Negative effects of commercial farming Commercial Farming removes the surface soil which causes damage to soil. These surface soils contain organic matter, plant nutrients and soil particles. This affects productivity on the farm. The erosion soil also clogs streams, rivers, lakes, reservoirs, which increases flooding, destroys habitats in the water, decreases the capacity of the reservoirs and decreases the populations of many fish and other aquatic life Conclusion Commercial agriculture can create a climate change. It has an input to global warming. From the pie charts below, you can see that commercial farming creates 12.5% of greenhouse gases in the atmosphere. You can also see that it produces 40% of methane and 62% of nitrous oxide. Instead of commercial farming, there is a better way to farm that won't hurt the environment. It is called "Aquaponics." It combines aquaculture with farming to create an environmentally friendly way to farm. The video below show how aquaponics work. You can see that commercial agriculture can create many problems in the environment. For example, it has a large contribution to water contamination, to soil erosion and to global warming. A better way to farm is to use Aquaponics. It is an environmentally friendly way to farm, which is much better than commercial farming. Water Pollution Wetland Drainage In many parts of the world the farmers drain wetlands to create areas for farming. This can lead to the loss of ecologically important wetlands like in the picture below. By draining these important wetlands, we are destroying the habitats of many aquatic species. Commercial farming has a large contribution to water pollution. The pesticides, fertilizers, and manure used in the farms can get into the run-off, or the underground water which can lead them into the bodies of water. Also when the animals have direct access to waterways, they can pollute more directly, and can add sediment by breaking down stream banks. Pesticides, fertilizers, and manure from farms can end up in the bodies of water close to farms. This can make some aquatic plants and algae thrive. Then they multiply and can damage native eel and whitebait habitats, restrict swimming, boating and fishing, clog drains and hydro dam intakes, and spoils the appeal of waterways.
