Contemporary and challenging, this thought-provoking book outlines a number of the key dilemmas in animal welfare for today's, and tomorrow's, world.

The book explores the effects of fences on wild animals and human impacts on carrion animals; the impacts of tourism on animal welfare; philosophical questions about speciesism; and the quality and quantity of animal lives. The welfare impacts of human-animal interactions are explored, including human impacts on marine mammals, fish, wildlife, and companion and farm animals.

This is a 'must-read' book for animal and veterinary scientists, ethologists, policy and opinion leaders, NGOs, conservation biologists and anyone who feels passionately about the welfare of animals
