So what? Meat is too cheap anyway - it’s subsidized beyond reason and healthcare costs are crazy. Give it time and there’s a non-zero chance we won’t have an economy to care about due to climate change. This is a good step even if it’s ‘costly’.
Funds directed at educating the public on the amount of protein they actually need instead of high-protein diets would go a long way towards reducing energy consumption and emissions to help the climate. Lab-grown meat seems like the wrong direction when there are numerous good protein sources already.
