What are two major environmental impacts producing food has on an ecosystem?

Food production contributes, for example, to climate change, eutrophication and acid rain, as well as the depletion of biodiversity. It is also a considerable drain on other resources, such as nutrients, land area, energy, and water.

What are two important impacts of food production on the environment?

Food waste produces 3.3 billion tons of carbon dioxide, a greenhouse gas that contributes to climate change. If food waste were a country it would be the third largest emitter of greenhouse gases after the US and China. By the year 2050 the world’s population will increase 33% to 10 billion.

What are the environmental impacts of food production?

Agricultural production dominates many of the impacts. This is particularly true for impacts related to land use such as biodiversity and soil quality, impacts related to the use of pesticides (aquatic and terrestrial ecotoxicity), and impacts of the use of fertilizers and nutrient losses (N and P) in general.

What are the environmental impacts of food and agriculture?

At the global level, agriculture contributes to climate change through emission of greenhouse gases and reduction of carbon storage in vegetation and soil. Locally, agriculture reduces biodiversity and affects natural habitats through land conversion, eutrophication, pesticide inputs, irrigation and drainage.

What are the environmental impacts of food waste?

When food is thrown out and breaks down in the oxygen-starved environment of landfill it generates methane, a greenhouse gas 25 times more potent than carbon dioxide. Composting prevents this sort of pollution. For every tonne of food waste not sent to landfill, almost one tonne of CO2 emissions is saved.
