Ignorance really can be blissful. For people who care about animals, not knowing about laboratory testing or how their meat or milk is produced is easier than knowing and doing nothing. I for one can't claim ignorance. As a child, I knew all about beagles in labs. My father was active with The Fund for Animals at the time and I helped pass out brochures that displayed photos of beagles hooked to cigarette machines that forced them to smoke the equivalent of several packs a day. I would be speechless with anger and sorrow as I read the descriptions, but I was just a kid and didn't know what to do with that anger. These days, thanks to the Internet, I've been able to easily swap out household products with cruelty-free substitutes. But still, the experiments and superfluous testing goes on. It's a matter of money, as most things are, and that's a fight that may never be won.
As a teenager, I read The Ordeal of the Animals, and learned about the horrors of slaughterhouses and the advent of factory farms. Again I felt fury, but I believed that nothing I did would make a difference. Recently, in my efforts to offer books that delve deeper into issues of animal welfare, I've again felt that gut-gnawing anger. The images stick in my mind and keep me awake; the utter stupidity and greed that drive people and governments (and the military) to such rampant annihilation of wildlife, maltreatment of domestic animals, and destruction of natural resources are unbearable at times. But in reading these books and sharing them with others, I feel I am helping in some small way to educate and enlighten, and eventually maybe put a dent in the machine of injustice.
