I’ve also been thinking about this alot (receiving from the world and giving back in return - the endless interconnected relationship we all should have with our larger communities). I really like how Derrick Jensen put it - that in taking from the world (consuming, which as animals we must do to survive), we enter into a “contract” to in turn preserve and promote the health of the community of whatever we are taking. So if we hunt a deer, for example, we should do so in a way (and live our lives in a way) to ensure the continuation, and the health, of other deer. If we eat salmon, we should act to remove dams and restore the salmon population.
I think that it IS possible to take what we need from nature in such a way as to make the natural world better off for it. Not to control nature, or impose a human “order” onto it, but to promote diversity and health of the ecosystem. And I think that requires understanding our relationships with all the other beings in our wider community - the mindfulness that Blue Heron was talking about.
I also totally agree with Incendiary_dan:
Giving back often allows an ecosystems to give back to you in turn, like any healthy relationship.
It is helpful for me to remember that giving back to the land in this way - by promoting healthy relationships with all members of our community - actually does benefit us in concrete ways. So it is actually in our self-interest to do so! We only hurt ourselves by turning our backs on these relationships.
