It was an overnight decision for me.
I'm a biomedical scientist. I've killed hundreds of mice to perform experiments on them. The reason I'm comfortable with this is because a) the experiments could not be performed without animal models and b) the experiments would result in knowledge that might some day be beneficial to human health.
In fact, those are the criteria that researchers must fulfill before they're granted permission to experiment by the ethics committees. If I could perform these experiments on cell lines or biochemical assays instead of mice, I would do that instead. This is pretty much the same all over the world: if you don't need to harm an animal, you shouldn't.
One day it struck me that I wasn't applying these same ethics to my life choices. I don't need to cause the suffering and death of animals by contributing to the industries responsible. So I don't. Pretty simple.
