I've said before that I would never tell someone not to eat meat, but I will ask people to think about where their food comes from. If you change your shopping habits and buy only high animal welfare foods you can do your bit to help stop the devastating factory farming.
Let's go back to traditional family butchers and traditional greengrocers before we lose them for good. I always look for locally grown produce (meat and vegetables) because I believe in supporting local farmers. Think quality, not quantity - eat less meat but better quality meat that is free from preservatives, antibiotics and other horrible things from the artificial feed factory farm animals are given.
Let's take a step back and encourage farmers to return to the old way of farming with animals out in the fields living natural lives.
"Since we can't count on the meat, egg, and dairy industries to protect animals from the most egregious forms of cruelty, what can we, as consumers, do? Opting out of paying someone to allow animals to die in a barn fire or at the slaughterhouse seems pretty reasonable." Ingrid Newkirk.
