I have touched this topic previously and will just make a reprise on the fact that in the World the number of Lab animal experimentations are increasing.
That’s a sad fact because , it is just a political dilemma. Sick people’s organisations and sick people are demanding more animal experimentations.
Well, back in my Med School days at a famous Med School my teachers said the experiments were useless. Despite that we sacrifice billions of animals. And it could even be dangerous for humans. Don’t we all remember what happened in the UK some years ago ,when chemicals were harmless on animals , but almost killed the experiment humans , often poor students that risk their lives for testing new medicines.
Just take the old example that chocolate can kill your dog and milk and lactose products are harmful to Hedgehogs but cigarettes fimps are compelety OK for Hedgehogs!
