Is profit possible without surplus? How much surplus is possible in a ustainable system?

The Stewardship of Creation

While reading about energy and sustainability this weekend, I briefly considered one Christian response -

Sins against environment are serious because they harm the common good and are counter to reason in other ways, but
even these sins pale in comparison to the explicit rejection of God? Even though these sins may involve great injustice and cause the suffering of many, they can still be forgiven -- Christians must keep this perspective even if they share the same concern as non-Christian environmentalists, who may be inclined toward fatalism or misanthropy, particularly when they make prognostications and talk about solutions (such as population reduction). (With the supposed affinity between Pope Francis and Ecumenical Patriarch Bartholomew in mind... I think they do give a proper Christian understanding of the stewardship of creation.)

Message for the 2012 World Tourism Day

"Along this way, the energy problems have to be taken into due consideration. It is an erroneous assumption to think that “an infinite quantity of energy and resources are available, that it is possible to renew them quickly, and that the negative effects of the exploitation of the natural order can be easily absorbed”.[3]"

All very diplomatic, no talk about re-engaging simplicity.

"Human beings, in fact, come first. We need to be reminded of this"

Was looking at the program for this year's New Wine, New Wineskins Conference and this caught my eye: Michael J. Martocchio, “The Ethics of Sustainability”

I assume this is he, listed as a member of the adjunct faculty at Duquesne.
