> The source of power to the lab feels like a separate issue. It would be a very intense stance to take that having your city grid on non-renewable resources means any product made in that city is bad for the environment! That's not what I'm proposing. Nature is very efficient so I imagine the energy that it takes to create a pound of flesh naturally (with grass) is alot less than that to required to do it in the lab. From a little googling and back of the envelope calculations I just did it turns out methane is really that bad for global warming. At least in the short term. To produce a cow worth of fake meat you would have to displace more than 16 tons of C02 before it becomes a less efficient way to produce meat from a global warming perspective. This assumes the cow has been raised using ancient methods. However this is in the short term. C02 lasts longer in the atmosphere.
