Deforestation of rainforests
On the agricultural land needed to produce one kilogramme of meat, 200 kilogrammes of tomatoes or 160 kilogrammes of potatoes could be harvested in the same time period. To gain more land area, rainforests are cleared, mainly for pasture or fodder cultivation.
To produce one kilogram of meat, 7 to 16 kilograms of grain or soybeans are needed. If this grain was fed to people directly without going through animals, there would be enough food for everyone.
Less water consumption
With the amount of water needed to produce one kilogram of beef (15,500 litres), one could take a shower every day for a whole year.
Less greenhouse gases
According to the Food and Agriculture Organisation of the United Nations (FAO), meat production causes more greenhouse gases than all global traffic. Many experts see dietary change as the most important factor in combatting climate change.
