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?

How much fossil fuel was burned for the energy required to research and publish this drivel? Was the research staff fully gender, lgbt, and ethnically inclusive? Were anyone's microaggressions triggered? How many puppies were tortured and killed?
Ye gods...

Hmm, LGBT I'm not sure. I clicked on the author's name over at SpringerLink to see xyr other papers, and I discovered xe's a clown. So, while xyr name isn't Mohammed, at least they (crap, gotta look this one up, let's see, no motion, present tense, subject, ah! wait, now John Cleese is asking me how many clowns there are, and it looks like it remains they) they've got general clown diversity covered.
Hmm, microaggressions. Well, many people find clowns to be frightening as was reaffirmed in the fall. I'm sure I've committed a microaggresson somewhere in this comment, so that should count.
I wasn't able to find anything concrete on C. familiaris, but there was this on page 16 of The Terminator (Homo exterminans) [springer.com] (click through to PDF on that page):
MAMMALS: Half the globe’s 5491 known mammals are declining in population and a fifth are clearly at risk of disappearing forever. 1131 mammals across the globe are classified as endangered, threatened, or vulnerable.
So I think the answer is: many. But xe didn't discuss whether T-600s or T-800s were more effective at killing puppies so I'm not able to be more specific than that. My gut says that the T-800 should be more effective because of its infiltration capabilities. On the other hand, we learn in T2 that T-1000s especially hate puppies.
However, to circle back around to the question of LGBT diversity, xe does discuss homos at length in that paper. See “The Age of Homo” pp. 23–25.
