I don’t remember when first I heard Them calling, with their silvery voices, The little Angels of the trees and flowers. They offered to unlock my mi… - Jane Goodall

Farm animals are far more aware and intelligent than we ever imagined and, despite having been bred as domestic slaves, they are individual beings in their own right. As such, they deserve our respect. And our help. Who will plead for them if we are silent? Thousands of people who say they ‘love’ animals sit down once or twice a day to enjoy the flesh of creatures who have been treated so with little respect and kindness just to make more meat.

"Most of us don't realize the difference we could make. We love to shrug off our own responsibilities, to point fingers at others. "Surely," we say, "the pollution, waste, and other ills are not our fault. They are the fault of the industry, business, science. They are the fault of the politicians," This leads to a destructive and potentially deadly apathy."

Michael Pollan likens consumer choices to pulling single threads out of a garment. We pull a thread from the garment when we refuse to purchase eggs or meat from birds who were raised in confinement, whose beaks were clipped so they could never once taste their natural diet of worms and insects. We pull out a thread when we refuse to bring home a hormone-fattened turkey for Thanksgiving dinner. We pull a thread when we refuse to buy meat or dairy products from cows who were never allowed to chew grass, or breathe fresh air, or feel the warm sun on their backs.
The more threads we pull, the more difficult it is for the industry to stay intact. You demand eggs and meat without hormones, and the industry will have to figure out how it can raise farm animals without them. Let the animals graze outside and it slows production. Eventually the whole thing will have to unravel.
If the factory farm does indeed unravel - and it must - then there is hope that we can, gradually, reverse the environmental damage it has caused. Once the animal feed operations have gone and livestock are once again able to graze, there will be a massive reduction in the agricultural chemicals currently used to grow grain for animals. And eventually, the horrendous contamination caused by animal waste can be cleaned up. None of this will be easy.
The hardest part of returning to a truly healthy environment may be changing the current totally unsustainable heavy-meat-eating culture of increasing numbers of people around the world. But we must try. We must make a start, one by one.
