If you haven't gone Vegan/Vegetarian, Plant based or seriously cut back on your meat and dairy intake, then I suggest you take a serious look in the mirror. One can not complain about the injustices of the world, and be actively participating in it.
The late Dick Gregory said it best; "Because I am civil rights activist, I am also an animal rights activist. Animals and humans suffer and die alike. Violence causes the same spilling of blood, the same stench of death, the same arrogant , cruel and vicious taking of life. We shouldn't be a apart of it".
If you want change, start with yourself. No more excuses. If you don't do it for yourself, do it for your children, the animals, the planet. With the state of our world, it is no longer a "Choice", but a necessity that every human participate in healing our planet. A great place to start playing an active role in saving this planet, is to stop supporting animal agriculture/slaughter. Make your heart bigger than your stomach.
