Sustainable food systems have been argued to be central to many [1] or all [2] 17 Sustainable Development Goals. [3] Moving to sustainable food systems, including via shifting consumption to sustainable diets, is an important component of addressing the causes of climate change and adapting to it.
The reasons for beef’s particular inefficiency as a food source are the vast land and water resources (i.e., virtual water) required for cattle farming and the fact that cattle emit methane, a greenhouse gas. The impact of food production is more realistic and tangible when expressed in terms of carbon dioxide emissions per serving rather ...
Demand for less environmentally-damaging food production leads people to buy more organic and local food. Organic food is produced through agriculture that does not use artificial chemical fertilizers and pesticides, and animals reared in more natural conditions, without the routine use of drugs, antibiotics, and dewormers common in intensive ...
The interactions among water, energy and food are numerous and substantial. Water is used for extraction, mining, processing, refining, and residue disposal of fossil fuels, as well as for growing feedstock for biofuels and for generating electricity. [15] Water intensity varies in the energy sector, with oil and gas production requiring much ...
Lastly, consumers get important information about what ingredients the food was made with by reading the food packaging. [47] Bottled water is another example of a highly packaged food product that is considered a single-use plastic because most people discard it after they're done drinking the water. It is estimated that Americans throw away ...
On the demand side, limiting food waste is an effective way to reduce food emissions. Changes to a diet less reliant on animal products such as plant-based diets are also effective. [11]: XXV This could include milk substitutes and meat alternatives. Several methods are also under investigation to reduce the greenhouse gas emissions from ...
All types of meat but especially lamb and beef generate several times more greenhouse gas emissions in their production than plant-based foods. [1]Environmental vegetarianism is the practice of vegetarianism that is motivated by the desire to create a sustainable diet, which avoids the negative environmental impact of meat production.
Sustainable consumption (sometimes abbreviated to "SC") [1] is the use of products and services in ways that minimizes impacts on the environment. Sustainable consumption can be undertaken in such a way that needs are met for present-day humans and also for future generations. [2]
