the 26-30% that is now currently used for crops and grass for meat.... well... again in the numbers, we only would need to use not more of a 7th maximal of that (because of the amount of crops it costs to produce one kg of meat) for crops to counterbalance the use of meat. I would be surprised if almost all of the land that now is been used to grow crops for livestock can't sustain crops that is fit for human consumption. but again, we would need a lot less. And biofuel is also a big opportunity.Ennis wrote: ↑18 Sep 2017, 12:552 main ones - how much of the 26% used for meat production can be repurposed for something else? The 26% sounds like a really high number, but if it can't be used for other crops then who cares?
The 2nd one was the 'sludge' yeah - what does it consist off, and what would that be used for if it wasn't being fed to animals?
in fact, i wouldn't be surprised, if we would switch on a all plant based diet, with the efficiency it brings, we could scale up biofuels so much (and we need lot less oil for not transporting cattle, crops to cattle, etc) that we wouldn't be oil dependent.
And the sludge, it is generally a mix of (GMO) soya, corn, slaughterhouse waste (cows eating cows!), grain and other veggies that are bought cheap. It all starts life basically the same as human food but is just handled differently (there is no real "health and safety" for animal food in the extend as for humans). Don't forget, crops for animals are the biggest "client" of crop farms, not human food, many people think or assume it's the other way round.
If you're a meat lover or vegan, or whatever, I think we should all agree the balance is all off.
