How many animals die each year from circus abuse?
Granted animals that are part of circuses have some definite disadvantages to put up with in life. However they are expensive and vets bills are also expensive so it is in the interest of the owners of these creatures to look after them as well as possible. The most obvious examples of animal abuse I have ever seen at circuses is that inflicted on animals by the passing public and their children. In any case very few circusses have animals these days.
