It's right though. Agriculture is the worst polluting industry in the world in terms of its carbon footprint. What's more, it also consumes around 30% of all freshwater consumption in the world. Meat is far and away the worst offender for that. For instance, it takes around 15,000 litres of water to produce 1kg of beef. That's not to say that crops aren't impactful and it's particularly bad how fuel crops are helping to flatten vast quantities of the Amazon, but even there, around 5,000sqm of the Amazon is being cleared each year for cattle farming, with agriculture as a whole said to be responsible for 80% of all deforestation.
