Meaning
Food production is a number of processes that humans use to feed the human population.
About Food Production and the Environment
- Many methods of food production can have damaging effects on the environment.
- At the time of writing this the population of Earth is increasing which means more food must be produced. Where food production is inefficient more land is being used to produce food.
- When more land is used for food production it must be taken from natural habitats so involves habitat destruction such as deforestation.
- During food production in many locations fertilisers are used which may be harmful to nearby habitats. When nitrate fertilisers are used they can be washed, by the rain, into local streams and rivers causing eutrophication.
- Food production may also use pesticides which include herbicides which kill unwanted plants and insecticides which kill unwanted insects. This further damages the local ecosystems.
