Hacking Meat: Can technology make us eat fewer animals?

Very sustainable?

"Food production requires application of fertilizers containing phosphorus, nitrogen and potassium on agricultural fields in order to sustain crop yields. However modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource and current global reserves may be depleted in 50–100 years."

Raising animals to eat is a much less efficient use of non-renewable phosphate than eating plants ourselves.

Some people in western culture choose not to eat animal products or meat, and have historically referred to themselves as vegans or vegetarians, respectively. Some of these people make the choice due to their ethical concerns about the food producing animals involved in the process. In this comment, they will be lumped into the group of "ethivegs". In my experience, a fair percentage of ethivegs are either luddites and technophobes, and vanishingly few of the technology embracing ethivegs are generally interested in science. Absolutely no ethivegs that I have met has been aware of in vitro meat research. Which is odd, since in vitro meat research meat has the ability to almost completely remove ethical concerns for an animal from the production of food.

Interestingly, PETA has heard of the technology and did a little advertising stunt for the research. Anecdotally, none of my NPR listening or PETA supporting acquaintances have ever heard of this stunt (which was on NPR) or the concept of in vitro meat. Happily, every single ethiveg that I have introduced to the concept of in vitro meat has felt very positive and excited about it.

So in my experiences with ethivegs, the consequence of in vitro meat research coming to fruition is this: eating meat will no longer require an animal to be treated unethically. Interestingly, many ethivegs have lamented that currently "unethical meat eaters" will no longer be punished with mad cow disease, high prices, or nutrient imbalances. However, they are generally more concerned with the ethical treatment of animals than they are with punishing humans who currently eat meat.

I find this interesting because some groups are less interested in correcting the sin, and more interested in punishing the sinner: http://i.imgur.com/Irgo2.gif

Extraordinary claims require extraordinary evidence. And some of your claims are extraordinary.

>What is it with this modern obsession with not eating meat?

It's not a "modern obsession". Varying degrees of vegetarianism have been part of human culture since ancient times. People, especially Americans, are eating far more meat than they did 50 or 100 years ago. There is a greater variation, but the mean is definitely rising.

>Meat is good. It's healthy

Meat consumption (particularly red meat and processed meat) has been linked to higher rates of cancer, cardio-vascular disease, and overall mortality in a dose dependent manner. Furthermore, some vegetarian populations are extremely long-lived compared to the their omnivorous peers.

>it's very sustainable

Meat eating is not sustainable at our current technological level. Mass production of animals to be slaughtered for our consumption accounts for the majority of human-caused methane production, causes the majority of anti-biotic resistant disease, requires many times the energy expenditure that growing plant-based foods do and is an enormous threat to bio-diversity.

If all the world ate as much meat as Americans, it would be a disaster in terms of public health and the environment both.

>* it's got an incredible protein:volume ratio,

Protein != intrinsically good.

>and it's delicious.

Taste is subjective, but a lot of people would agree with you.

I'm a highly technical "ethiveg" vegan and every vegan I've met have not only heard of in vitro meat but strongly supports it.

I am not an ethiveg. I ask literally every ethiveg I meet if they have heard of in vitro meat, because asking them is an incredibly easy thing to do, and if they spread awareness and generate support for the science then the world will be a measurably better place. I am impressed that you ask literally every ethiveg you meet if they have heard of in vitro. Keep up the good work, improving the world is the responsibility of all those who can help improve the world.
