A glass of milk for breakfast, spaghetti bolognese for lunch, a boiled egg and a couple of slices of salami for supper – this is a normal daily diet for many people. However, it contributes to global growth in the consumption of animal products. Especially in the developing countries, the demand for meat and other animal-based products is massively on the rise.
Not only do animals suffer as a result of this industry. Many people are unaware that increasing meat consumption has an effect on the climate and the environment.
Animal products are climate killers
Climate change is caused by the increased quantities of greenhouse gases we humans produce, such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N20), which enhance the natural greenhouse effect. These greenhouse gases are released not only by burning fossil fuels (e.g. coal, natural gas, oil) or by transportation (cars, ships, airplanes). Livestock farming and the production of animal-based products have serious effects, too.
Worldwide, 14.5 percent of total man-made greenhouse gas emissions are from animal production, of which the beef and dairy industries – mainly due to the high demand for animal feed and the release of methane – are the biggest climate polluters in the sector.
Compared to the production of fruits and vegetables, much more energy is needed to produce meat, milk, cheese and butter, resulting in more CO2 emissions. The increased production of nitrous oxide and carbon dioxide is mainly caused by the fertilisation of agricultural land and the production of mineral fertilisers and pesticides.
- The deforestation of woodland and tropical forests to create pastures or areas for growing animal feed such as soya.
- Water shortage and pollution: a huge amount of water is needed in the various stages of meat production and the production of other animal-based products (e.g. 15,000 litres of water are used to produce just one kilogramme of beef). The overfertilisation of agricultural land as well as the use of pesticides and medicines lead to the pollution of water resources.
- Biodiversity loss due to the deforestation of tropical forests and changes in grassland areas in order to create agricultural land.
