Significantly more resource-intensive
- Animal agriculture is significantly more resource-intensive, using more water and land, emitting more greenhouse gases, and delivering less of the population’s nutritional needs.

Apr 20, 2016 · Production of animal-based foods accounted for more than three-quarters of global agricultural land use and around two-thirds of agriculture’s production-related greenhouse gas emissions in 2009, while only contributing 37 percent of total protein consumed by people in that year.

Jul 4, 2017 · Farming Plants – A Comparison. A report from the Humane Party analyzes the land-use, efficiency, and profitability of animal farming versus plant farming. The fact that animal agriculture is much more resource intensive than plant agriculture has become fairly well known among animal advocates.
Sep 20, 2021 · Breaking down this share, production of animal based foods – meat, poultry and dairy products, including growing crops to feed livestock and pastures for grazing – contributes 57% of emissions linked to the food system. Raising plant-based foods for human consumption contributes 29%.
Sep 7, 2020 · Ongoing agricultural emissions can be abated by shifts to less-resource-intensive, plant-based diets 6, 7, but the potential for cumulative CO 2 removal from native vegetation regrowth in...

- Reduce food loss and waste. Approximately one-quarter of food produced for human consumption goes uneaten. Loss and waste occurs all along the food chain, from field to fork.
- Shift to healthier, more sustainable diets. Consumption of ruminant meat (beef, lamb and goat) is projected to rise 88 percent between 2010 and 2050.
- Avoid competition from bioenergy for food crops and land. If bioenergy competes with food production by using food or energy crops or dedicated land, it widens the food, land and GHG mitigation gaps.
- Achieve replacement-level fertility rates. The food gap is mostly driven by population growth, of which half is expected to occur in Africa, and one third in Asia.
Given that both per calorie and per gram of protein animal foods are significantly more resource-intensive than plant foods, [12-14] scholars have argued that the cheapest, easiest, fastest and most effective action that can be taken at a global scale to help mitigate climate change is a dietary shift towards consuming more plant-based foods ...
The worldwide phase out of animal agriculture, combined with a global switch to a plant-based diet, would effectively halt the increase of atmospheric greenhouse gases for 30 years and give ...
