How does agriculture and food production affect the world

image

Agriculture, deforestation and other land use for food production account for roughly 20 percent of all GHG emissions, making it one of the largest contributors to climate change and global warming. This is more than the emissions from cars, planes and trains combined and the energy sector is the only other sector with a higher share of emissions.

Agriculture is the world’s largest industry. It employs more than one billion people and generates over $1.3 trillion dollars worth of food annually. Pasture and cropland occupy around 50 percent of the Earth’s habitable land and provide habitat and food for a multitude of species.

Should bodies be sacrificed in the production of food for others?

We also believe that certain people’s bodies should not be sacrificed in the production of food for others—as is the case of millions of farmworkers and other food producers subject to grueling and dangerous labor conditions and exposed to toxic chemicals in fields and processing plants.


What is the water footprint of food?

The water footprint of food products gives a useful indicator of their environmental impact. But freshwater scarcity varies across the world: some regions have abundant water resources (meaning agricultural water demands have little impact) whilst others experience severe water stress.#N#We can also look at water footprints in terms of scarcity-weighted freshwater use. Scarcity-weighted water use represents freshwater use weighted by local water scarcity.


How much of the world’s calories are thrown away?

Around one-quarter of the calories the world produces are thrown away; they’re spoiled or spilled in supply chains; or are wasted by retailers, restaurants and consumers. 44 To produce this food we need land, water, energy, and fertilizer inputs. It all comes at an environmental cost.


What are the main sources of methane?

Livestock – animals raised for meat, dairy, eggs and seafood production – contribute to emissions in several ways. Ruminant livestock – mainly cattle – for example, produce methane through their digestive processes (in a process known as ‘enteric fermentation’).


Does transportation add to carbon?

For food that is transported by sea, transportation doesn’t actually add much to the carbon footprint. Since most of our food is transported by sea, transport emissions only account for 6% of the carbon footprint of food, on average. 41.


How have humans replaced forests and grasslands?

Humans have replaced permanent forests and wild grasslands with farm fields that allow much higher rates of soil erosion where the soil is not covered year-round. This has led to trillions of tons of soil being washed into rivers, lakes, and oceans, where it is unavailable as a key resource for food production.

Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture.
