It's the food chain.
This is a baseless excuse.
It is a chain of events that bring food to humans. But we could have a Vegan food chain. Also we have to talk about shops and supermarkets! These are the real food chains.
Also the majority of land animals in the Uk are put in gas chambers, there is no way to argue that this is a good thing.
Part of this excuse is that we eat animals like lions do. But the majority of the land animals on earth are herbivores.
The great news is that it's really easy to live a Vegan lifetyle. Veganuary is a great website to help.
