Maybe, just maybe buying animal-products, where the animals didn't suffer, where they were raised species-appropriate, would help, as it would be a ecological signal as well.

If more people would do that, a lot more incentives would be there, to not let animals suffer just for human consumption.

Since I switched to only eating animal products, where I know, how the animals lived, I do eat a lot less meat. i do pay a lot more (and I do that consciously). And I have the benefit, that it also does taste so much better, that I really enjoy this in more then one way, when I eat it (sometimes pork-steak, sometimes ham, sometimes goat-salami). We buy at a local farm, that raise, slaughter and process the meat all by themselves, and produce at least 50% of the food that is needed for raising the animals on the farm itself.

So for me this was a viable alternative - but I could understand, if this is not possible in other circumstances of life.
