I deras artikelserie How you can make the world better har man listat tio saker som var och en kan göra för att rädda världen. Och en av dem är att välja vego, att äta mer grönt: "Eat less meat and more vegetables if you want to help save the world".
Under rubriken "Eat more plants" skriver man:
"Where the food you eat comes from matters less than what it is. The greenhouse emissions from transporting food are typically only a tiny proportion of the total emissions associated with growing food.
Livestock are responsible for nearly a fifth of all greenhouse emissions, from the methane produced by their guts and manure, to nitrous oxide emissions from the fertilisers used to grow feed for them. Because it takes several kilograms of plant matter to grow a kilogram of meat, producing meat and animal products such as cheese usually greatly multiplies the environmental damage done by farming. The huge amounts of land required are driving the destruction of rainforests, for instance. Even small reductions in consumption, such as making Mondays meat-free, could make a big difference."
