If we priced externalities at their true societal cost, the problem of animal farming becomes clear very quickly. Reducing carbon emissions from animal agriculture is one of the bigger targets for helping reduce climate change. I don't think telling people to just not eat meat will work, so lab-grown meat seems like a promising solution to explore.

- runarberg 4y agoDoesn’t lab grown meat need a lot of growth serum, which is currently extracted from pregnant animals? So as it stands it is not a solution to help reduce climate change (nor animal suffering). For that we’d need a more sustainable way of producing these serums. I’m not aware of any methods which are proven to work at scale.
- coldpie 4y agoBeats me! I don't expect it to be more efficient today, it's brand new tech. My hope is that it will be much more efficient as research continues & economies of scale start to kick in. It may well turn out to be a dead end, but until that's clear, I think it is exciting to think about.

- AS37 4y ago> Doesn’t lab grown meat need a lot of growth serum, which is currently extracted from pregnant animals? 5 years ago it took ~50L of fetal bovine serum (FBS) to grow a burger, at around USD 400/L. FBS is made from the blood of unborn calves, which are taken from slaughtered cows. All lab meat companies are obviously looking to reduce that input cost by finding a replacement.
