How are Biomes altered to make way for food and non-food agriculture?
Intense farming makes pollution because of the use of pesticides, these have a substantial amount of chemicals which effects the environment.
Using pesticides on plants.
For example: Horticulture farmers use fertilizers to help the growth of root crops, which effects the hydrosphere. The rain water runs the chemicals down and into bodys of water including lakes and rivers. Eutophication is a problem caused by this.
Eutrophication: excessive richness of nutrients in a lake or other body of water, frequently due to run-off from the land, which causes a dense growth of plant life.
Another example is cotton this is non-food farming and has the same effects as root crops. Cotton farmers use an intense amount of pesticides on their crops , and even though cotton farms only take up 2.5% of the worlds farming land it is still an issue.
Changing the soil is affecting the animals and insects that live their, this changes the environment because new animals come.
The environmental and egological impacts on agriculture are
Land conversion and Habitat loss
Wasteful water consumption
Soil erosion and degradation
