Are these things to be regretted only’ because of the loss to humans or other sentient creatures.9 Or is there more to it. than that Some philosophers are now prepared to defend the view that trees, rivers, species (considered apart from the individual animals of which they consist), and perhaps ecological systems as a whole have a value independent of the instrumental value they may have for humans or other sentient creatures.
Our concern for the environment also raises the question of our obligations to future generations. How
A. the intrinsic value of human experiences
B. the intrinsic value of the experiences of nonhuman animals
C. the intrinsic value of ecological system as a whole
D. an ancient ethical question about the nature of intrinsic value
