On the whole, livestock production has a share of 18% of the CO2 equivalent in the greenhouse effect. This share is higher than all means of transportation worldwide. Livestock production releases 9% of anthropogenic CO2, 37% of anthropogenic methane as well as 65% of nitrous gases – primarily through the use of fertilizer

Livestock production is co-responsible for water pollution, dying forests, air pollution, cutting down rainforests, soil erosion and dying out of species.

The accusation to animal friends that they should work for starving people instead of the animals is unfounded, because: If mankind were to follow a vegetarian diet, no person on this planet would have to go hungry.
