I love leather, but I don’t love killing, so I just have a bunch of fake leather jackets – and they suck. I would love lab grown leather and lab grown meat.

Yay!
Very soon we will have fake real skin on dildos!

The only thing I’m interested in is the energy required to produce one kilo of each type, the cow’s lifetime methane emissions and the labs CO2 emissions.

I'm a leather craftsman, the majority of hides used in the industry are from cattles animals destined to meat consumption. Which means that skin is a by-product of our meat usage and would be destroyed if we didn't use it elsewhere, like making bags and all. The only animals that are killed only for their skin are the "exotic" ones, like snakes, crocodiles, frogs, ... etc. Which for me is kind of sad to see.

I'm excluding fur from all of this.

As long as its cost is the same or higher, nothing will come from this. Similarly to synthetic mica in cosmetics. It's not only free from the ethical issues, but also higher quality. And yet, almost all companies continue using natural mica - sourced from India's child labor - because it's cheaper.

Another example is gelatin in jellies. It's disgusting and makes inferior candies, but it's cheaper and so all the companies use it.

The market's invisible hand, eh?

Just give me dragon leather

I don't know if that image is the lab-grown or not, but I came here to say it looks like balls.

I love this, and I hope they find success with this. I also hope they find a way to make it not look like something out of Ed Gein's collection, because right now it's hideous.

who is very much alive, grazing at an animal sanctuary in upstate New York.

Riiiiiight. A farm upstate.

I wonder how it will stack up to the mushroom leather.

Did we finally figure out how to get four steaks worth of meat from a horse without killing it?

You'll still get shit from PETA.

Poor wording in the title. All leather came from living cows.

sorry i like organic, free range, USDA, non-gmo, fairtrade leather. no big pharma stuff /s

Pretty sure all leather comes from some cow who was living at one point...😛

FFS....lab grown meat, lab grown cow skin cells, they all grow being fed fetal bovine serum, which is not taken by donation.

sustainable breakthrough that could cut emissions and eliminate slaughter in the $400 billion leather industry

Seems pretty pointless when leather is a byproduct of slaughter for meat, and meat (not leather) drives the demand for cows. Even at 0 leather demand, cow slaughter & their impact on the environment would continue at the same levels.

For the slow: if we switched entirely to lab-grown leather, then what would we do with the unused cowhide stripped from butchered cows? Let it go to waste while redundantly pumping unnecessary resources to grow the same thing in the lab? That's massively stupid.

This reminds me of the invention of edible food wrappers entirely missing the point of wrappers protecting the food from contamination which would now include the wrapper needing protection.
