"At the descriptive level, certainly, you would expect different cultures to develop different sorts of ethics and obviously they have; that doesn't mean that you can't think of overarching ethical principles you would want people to follow in all kinds of places"

This quote by Peter Singer recommends that although various cultures have developed different ethical concepts, there are still overarching ethical principles that should be followed in all places. This suggests that although cultures may have different values and beliefs, there are still some universal ethical concepts that should be respected and followed. This could consist of principles such as regard for human life, regard for the environment, and regard for the rights of others. Singer's quote suggests that although cultures may vary in their ethical principles, there are still some universal ethical principles that ought to be appreciated and followed in all locations.
