De Laplante (2006) identifies two key questions in environmental philosophy: whether humans have moral obligations to protect the environment and the justification of those obligations, as well as the underlying causes of contemporary environmental attitudes and potential changes. The document discusses concepts of freedom in the context of moral obligations and determinism. It highlights the ongoing debates within the academic community regarding environmental ethics.

6. De Laplante (2006) summarizes two
major sets of questions that divide
the academic community on the
subject of environmental philosophy:
(1) Do human beings have moral
obligations to protect or preserve
the natural environment? If so,
what are they, and to whom, or
what, are they owned? How are
such obligations justified?
(2) What are the root causes of
contemporary attitudes and practices
with respect to the natural
environment, and how can we change
them? (p. 48)

begins when
another's freedom
ends.
