"And we will evolve out of eating animals..."
Most unlikely. Not everyone wants to ignore the reality of nature and the food chain because of some misguided beluefvthat it's miral to do so.
"the alternatives are better"
Er, they aren't. They can be ok but unless they mimic meat they are likely inferior, and if one has meat, there's no heed to mimic it.
"it is wasting the planet feeding the animals to feed us... time to cut out the middle man/cow/pig/sheep/fish.....?"
No, that isn't so, as explained above meat is a better more desirable meal, without needing to analyse our food to ensure vital nutrients are being consumed. What is wasting the planet is an inability to control breeding and overpopulating Earth.
