Cows are over 50% of the biomass of all the animals of the planet combined. They graze areas larger than all of our cities and villages put together, are nearly immune to disease and physical injury, and have the guarantee of safety from every predator except these mysterious ape gods which assign each of them a predetermined life time. Speaking in terms of evolutionary success, I don't think they are complaining.
That being said... if we want to preserve anything of value in nature, I hope lab-grown meat becomes a widespread, economically viable alternative as soon as possible. There's a bulging middle-class of billions coming from Asia and Africa which aren't going to shy away from meat that easily. No ammount of pointless ethical debates or pleas from more developed countries will change the minds of the majority until it is too late.
