Animal testing is always a weird one. I love animals. I've studied Zoology. I want to be an Ecologist. The thought of animals being born just to be tested on and then euthanised at the end of the study is distressing. However it doesn't change that I probably wouldn't be alive if animal testing didn't exist. You probably wouldn't be alive either. Somewhere in our family tree, someone who benefited from the treatment would have gone without and died.

Given that I'm alive because of animal testing, if I then go on to look after animals, or work in ecology and protect the environment by using my abilities to save and protect more animals, is that a worthy trade off when you extend it to include everyone who works with animals or fields that benefit animals in a positive way? What about people like David Attenborough, who has reached billions with his message of protecting animals and the environment and will continue to do so for generations thanks to film?
