Meat is animal flesh that is eaten as food. It often refers to the flesh of mammalian species (pigs, cattle, lambs, etc.) and not to the flesh of fish and other seafood, poultry, and other animals.[1]

Impacts on the environment

The environmental impact of meat production greatly depends on factors such as:

  • the type of meat/animal,[2][3][4]
  • the feed used

However, regardless of these factors, traditional meat production will still have following negative effects:

  • Production of methane by ruminants (mainly cows). Methane is a powerful greenhouse gas. Is this worse for grain-fed cattle than for grass-fed cattle?[expansion needed]
  • Destruction of natural habitat to create land for cattle
  • Destruction of natural habitat (e.g. rainforest) to grow food for cattle.
  • Competition for food with humans - this means that wealthier people eating lots of meat increases the price of agricultural produce, which makes life harder for poorer people. This may not be an issue where:
    • The animals live on scraps
    • The animals live on other feed which humans do not eat, e.g. grass (cattle), household scraps (pigs, goats, chickens) and insects and seeds found in a garden (chickens, ducks).

    • 1 kg of porc meat produced 3,9 to 10 kg CO², 8,9 to 12,1 m² of land is required (land use)
    • 1 kg of beef (cattle) produced 14 to 32 kg CO², 27 to 49 m² of land is required (land use)
    • 1 kg of milk produced 0,8 to 1,3 kg CO², 1,1 to 2 m² of land is required (land use)
    • 1 kg of chicken meat produced 3,7 to 6,9 kg CO², 8,1 to 9,9 m² of land is required (land use)
    • 1 kg of eggs produced 3,9 to 4,9 kg CO², 4,5 to 6,2 m² of land is required (land use)
