Opinion: "The End of Meat Is Here" - NY Times

It's not my words. Try cutting out your knee jerk, pro-meat denial and read the source.
I didn't say they were your words but it's definitely in the link you quoted without stopping to think for even a second if that 73% could possibly be right. :facepalm:
 
Um, I have been growing flowers and vegetables on my allotment for over 20 years - the last 8 or so without manure (because of herbicide issues). My soil is totally played out and will need a year of having a leguminous covercrop and a bloody great infusion of shit.* Flowers grow perfectly well, relying on photosynthesis for their needs, but calorific vegetable crops are en entirely different proposition, not least because I don't dig the flowers up every year to eat them. Calories in, calories out, the sunlight requirements and fertilser needs of annual crops are much greater than perennial ornamentals, trees, shrubs and such. Also, it isn't just about fertilser either. I could throw a granular chemical fert on the ground every year...but the soil structure and complex skein of micro-life is also damaged by continual digging, harvesting and replanting. It is a difficult and complicated issue but even my non-scientific brain can see the need for manure to provide, not just nutrients but also, moisture maintaining humus. It seems entirely obvious to me - if everyone ate a third less meat (at least) and dispensed with the ridiculous protein abundant diets we have become accustomed to, the earth has a carrying capacity to feed everyone, including maintaining a pastoral tradition where plants and animals have a symbiotic and harmonious co-existence. Intensive agriculture is as deleterious to topsoil (a finite and precious resource) and the wider environment as battery farming. Not least because of over-use of pesticides. It is a question of both scale and lack of diversity.These shitty black and white, binary arguments are always doomed to failure...and utterly without merit when there are abundant ways of ensuring food security.

* which I have finally got my hands on now that my neighbouring beef farmer has switched to no spray herbal leys. Thank fuckety fuck.

The number comes from the University of Oxford's major study which was cited as "the most comprehensive database yet on the environmental impacts of nearly 40,000 farms, and 1,600 processors, packaging types, and retailers."

Specifically, plant-based diets reduce food’s emissions by up to 73% depending where you live. This reduction is not just in greenhouse gas emissions, but also acidifying and eutrophying emissions which degrade terrestrial and aquatic ecosystems. Freshwater withdrawals also fall by a quarter. Perhaps most staggeringly, we would require ~3.1 billion hectares (76%) less farmland. 'This would take pressure off the world’s tropical forests and release land back to nature,' says Joseph Poore.

The researchers show that we can take advantage of variable environmental impacts to access a second scenario. Reducing consumption of animal products by 50% by avoiding the highest-impact producers achieves 73% of the plant-based diet’s GHG emission reduction for example. Further, lowering consumption of discretionary products (oils, alcohol, sugar, and stimulants) by 20% by avoiding high-impact producers reduces the greenhouse gas emissions of these products by 43%.


Now show everyone why you're so sure the scientists are wrong and be sure and support your assertions with credible studies and research.

Looking forward to it!

That quote isn't the same as your original quote. Both can't be right as they are different things so is there a cockup in the report? Or have you misquoted? And if so why? :hmm:

So you agree that "up to 73%" is entirety accurate, yes?

My original quote was a precis of the report, You understand how they work yes?
 
Because I've already done so and commented on them in the past and I don't have the energy to keep repeating it ad nauseam every time you bring it back up again as 'evidence'. :(
Shitting fuck, its only Poore and Nemeck (2018) again.

Is there some sort of competition for how many times a person can bring up the same fucking study (often reported by different outlets) over and over and over.
Maybe I'll just merge my critique of it (peer reviewed) with the later ones from elsewhere in the literature and just repost it ad nauseam.
:facepalm:
 
Be sure to give what you believe is the real figure and back that up with credible scientific research, otherwise you're just making shit up.
How much travel are you prepared to allow when it comes to shipping food; do you imagine we eat only what grows here? In the EU? Worldwide shipping?
 
No, growing plants involves the poisoning of billions of organisms, including rodents and insects,
Growing plants involves macerating them in combines, slicing them with ploughs etc etc.

Also, growing plants intrinsically takes fertility away from the soil - two things can put it back, manure and petrochemical fert (slightly aided by legumes/rotations)
This is happening anyway for fodder/feed for livestock and poultry is it not? It cuts both ways.
 
So you agree that "up to 73%" is entirety accurate, yes?

Claim 1) a reduction in an individual's carbon footprint of 73% (post 1170); claim 2) a reduction in food emissions of 73% depending on where you live (post 1234). Do you recognise these claims?

No because animals holistically return all their nutrients to the soil somehow and never mind the basic fact that primary consumers are an order of magnitude less efficient as a source of energy than producers, hence only one buzzard to every hundred bunny rabbits.

Also never mind the fact you can't compost unwanted bits of cow or pig because it would create a biohazard, so the entire animal and all its nutrients and minerals has to be taken away from the system and its soil.
 
Maybe they have, but it'd be news to me. And to a lot of other people, "photosynthetic inversion" being a phrase never before used by anyone as far as I can tell.
I’ve lost all fish in my fish pond one very hot summer day due to sudden algae and that was with a pump working, it does happen.
 

Fish famously an intrinsic part of a field ecosystem of course.

Do farmers produce that stuff in house from their own extraneous animal bits? No. Is it produced by composting? No. So that picture of a bag of fertiliser doesn't really disprove my assertion that nutrients in animal carcasses cannot be composted or returned to the soil by the farmers who created them.

I'm sure it does. 'Photosynthetic inversion' however, well if it does exist it was discovered by our own Funky_monks who then proceeded to tell nobody else about it, never mind publishing his work. There are zero google results for that phrase. Which in itself is kind of an achievement in this day and age.

I googled photosynthesis inversion and found this immediately, perhaps this is what Funky_monks meant?

I've invented photosynthetic inversion at night?
Think it's on the GCSE syllabus, if not definitely A-level
:D :D :D :D

You can also get pure bonmeal if it suits you.

What extraneous animal bits do you suppose farmers have lying about?

Me showing you the incredibly common fertiliser made from the only animal bits routinely wasted doesn't disprove your theory that unused animal parts can't be returned to the soil? :D:D

That's an article about a misconception of what photosynthesis is. It's easy, but wrong, to describe photosynthesis and respiration as directly opposite processes because the products of one are the reactants of the other (provided you're willing to reductively lump in lots of different molecules as 'glucose' as the GCSE syllabus requires us to do) and vice versa. Respiration and photosynthesis are both sequences of largely independent reactions, sequences which may not be completed in the absence of certain limiting factors but which may still be biologically useful. When you break these processes down into their component reaction stages it becomes clear that none of those stages has an opposite version in the other process.

How a misconception can murder pond life remains unclear.
