Vegetarian and (especially) vegan diets are better choices ethically and for the planet, but if you are going to eat meat it's best to make sure that it comes from animals that are humanely treated and with more sustainable raising practices than the current factory farming methods. Here are a few resources for compassionate-sustainable carnivores. I started out with links I found in the book "The Way We Eat: Why Our Food Choices Matter" by Peter Singer and Jim Mason but will add others as I come across them and learn more.

• Eat Kind

To find farms using non-factory farmed methods:

• Eat Well Guide

• Eat Wild

Grass and pastured-based farms:

• American American Grassfed Association

• American Pastured Poultry Producers' Association

Humanly-raised:

• Heritage Food

Sustainable Fish:

• Seafood Choices Alliance
  
• Fish Forever Certification (from Marine Stewardship Council)
