So far the discussion is only on fossil fuels and items like concrete constructions but not on eating habits of people. The latter contributes much more to global warming and Ecological destruction. We often do not bring that to the top of the table since all discussion is essentially West determined.
- Livestock production accounts for 14.5 per cent of global greenhouse emissions, the same amount produced by all the cars, planes, boats and trains in the world. “A single cow can belch up to 500 litres of methane every day”, writes the BBC’s Dr Michael Mosley, a gas that is 25 times more potent than a carbon dioxide. “Multiply that by the 1.5 billion cattle we have on our planet and that’s a lot of gas.”
- It is inefficient. It takes, on average, 3kg of grain to produce 1kg of meat and two thirds of all agricultural land is used to grow feed for livestock, whereas only eight per cent is used to grow food directly for human consumption. These are “basic laws of biophysics that we cannot evade,” says the study’s lead researcher, Bojana Bajzelj from the University of Cambridge.
- It places pressure on dwindling freshwater supplies and destroys forest and grasslands, which are turned over for grazing. Soil erosion, soil and water pollution from fertilisers and animal waste are other ways the meat industry impacts the environment.
- Scientists also argue that we need to stop wasting so much food, as on average, 7.2 million tonnes of food is wasted in the UK each year.
