Every meal you eat now costs the planet 10 kilos in lost topsoil.
That's the warning of "Surviving the 21st Century" author Julian Cribb to an international soil science conference in Queenstown, New Zealand on Dec 15, 2016.
"10 kilos of topsoil, 800 litres of water, 1.3 litres of diesel, 0.3g of pesticide and 3.5 kilos of carbon dioxide – that's what it takes to deliver one meal, for just one person," Cribb says.
"When you multiply it by 7 to 10 billion people each eating around a thousand meals a year, you can see why food is fast becoming the challenge of our age."
"The human jawbone is now by far the most destructive implement on the planet. It's wrecking soil and water, clearing forests, emptying oceans of fish and destroying wildlife as never before – but few people realise it because of long industrial food-chains that hide the damage from them," he says.
Do the 10 kg of lost topsoil result in 10 kg of night soil?

Well that's a load of bullshit. The only people more damaging to a wild environment than farmers are indigenous people.

Yeah, that's why when whitey showed up in the New World the whole place was just trashed.

Why do you think most primitive people are nomads? Surely if they were "living in harmony with nature" they could just stay there. The truth is they trash an area until it is unlivable, and then move on and do it again. They were just sparse enough that the ecology could mostly recover before they came round again. They still drove many species into extinction.
It's not politically correct to mention it, but all the the Australian megafauna went extinct just after aborigines arrived here.
