Not all cultured meat is unethical or needs a regular supply of bovine calf serum and such. There was a recent crowdfunding campaign by SuperMeat [1] that focused on bringing cultured chicken meat to the market. It didn't reach the funding goals necessary to work on commercial production in about five years time though. With SuperMeat's method, a tiny painless biopsy would help in the creation of a few hundred tons of chicken meat. There needs to be more work on such methods even if there are failures or if the initial costs seem higher. [1]: http://supermeat.com http://supermeat.com
