The field of animal ethics is evolving rapidly. Since over 50 years, academic animal ethicists have been discussing the question of what moral agents owe to nonhuman animals. In the last decade, the political turn in animal ethics led to many publications about political duties owed to animals. Furthermore, animal ethicists started to investigate more in detail what, if anything, humans owe to wild animals. During the pre-workshop on Monday, 2nd of May at the University of Fribourg, the relationship of animal ethics and environmental ethics will be discussed. The aim of the main workshop on Tuesday, 3rd of May at the University of Basel is to discuss various in-progress articles in different domains in animal ethics.
