Livestock's Long Shadow "that livestock are responsible for 18 percent of greenhouse gas emissions" GHG emissions arise from feed production (e.g. chemical fertilizer production, deforestation for pasture and feed crops, cultivation of feed crops, feed transport and soil organic matter losses in pastures and feed crops), animal production (e.g. enteric fermentation and methane and nitrous oxide emissions from manure) and as a result of the transportation of animal products. Following this approach the report estimates that livestock contributes to about 9% of total anthropogenic carbon dioxide emissions, but 37% of methane and 65% of nitrous oxide emissions. Along the animal food chain, main
Recreational use of nitrous oxide to be sold for human consumption, 'food grade' nitrous oxide canisters, made for the purpose of prolonging the shelf life of whipped cream and other products are completely legal, and anyone can buy these without a permit. Recreational use of nitrous oxide Recreational use of nitrous oxide is the inhalation of nitrous oxide gas for its euphoriant effects. The gas is sometimes called Whippets, Laughing Gas, the Epiphany Drug, or Hippy Crack. In Australia, nitrous oxide bulbs are known as nangs. Nitrous oxide is a dissociative inhalant that can cause analgesia, depersonalisation, derealisation, dizziness, euphoria, and some sound distortion (flanging).
