Facts and statistics about vegetarianism

Here are some statistics that convey how in demand vegetarian meals now are in our society:

  • Courts: Every third dish published in Germany is vegetarian.₆
  • Restaurants: In 2016, there were already 616 purely vegetarian restaurants in Germany's large and medium-sized cities. In 2015, there were 317 and in 2013 only 214.₇

Vegetarian statistics on the reasons for giving up meat

Common motives for the vegetarian diet are, for example, animal welfare, the World hunger and the Water shortage, climate and environmental protection, allergies or health problems. From this, some valuable facts and figures about the reasons for vegetarianism can be derived:

How many animals are killed for nothing every year?

  • Food waste: Every year, 356 million kilograms of meat are simply thrown away in Germany. 45 million chickens, 4 million pigs and 200,000 cattle therefore die in vain.₈

How much water is used for 1 kilogram of beef?

  • Water consumption: 15,000 liters of water are needed to produce one kilogram of beef. For example, for watering, cleaning stalls or growing feed.₉ See also Environmental problem of water scarcity.

What vegetarian facts are there about raising cattle?

  • Cattle breeding: Around the world, about one billion cows graze on the green meadows of this earth today.₁₀ Cattle emit large amounts of methane on the meadows. The gas is about 25 times more harmful to the climate than the CO2.₁₁ Brazil breeds the world's largest cattle herd with 180 million animals.
  • Cattle feed cultivation: Around 61.8 percent of arable land in Germany is used to grow livestock feed. We consume only 21 percent of the harvest directly ourselves.₁₂
  • Deforestation: Amazon rainforest in particular is being cleared for the pastures - 100,000 km² from 1996 to 2006 alone.₁₃ More at Factory farming.
  • emissions: According to the Food and Agriculture Organization of the United Nations (FAO), livestock farming causes about 15 percent of global greenhouse gas emissions.₁₄ So becoming a vegetarian is one of the best Climate protection tips for everyday life.

What other facts are important for vegetarians?

  • Fishing: Every year, we globally fish about 90 million tons of fish from the oceans.₁₅ For more information, you can take a look at the post with the Statistics on the overfishing of the seas.
  • Fish as feed: In fact, about 40 percent of fish caught worldwide are fed back to livestock.₁₆
  • Health: The risk of coronary heart disease is 22 percent lower in vegetarians (and vegans) compared to meat eaters, according to a scientific study.₁₇

  • ... then about 33 million square kilometers of land would be available. That is a larger area than the African continent.₁₈
  • ... we could reduce greenhouse gases emitted by humans by 15 percent.₁₉
