Peta stands for The People for the Ethical Treatment of Animals (PETA) Foundation and is a UK-based charity dedicated to establishing and protecting the rights of all animals. This January 2021 they are teaming up with Waterstones book retailer chain. That means you can pick up the book with a discount in one of their 283 shops in UK and elsewhere, but the better option, due to the corona situation, would be to order it online from this page. Please remember to add the discount code at the checkut: PLANT21.
