Aspects of Ecology

A few weeks ago, I read about growing controversies in France, around the topic of gay marriage, stemming from the enactment of the Taubira law.  What caught my interest was that some of the critics' point of view stemmed from a critique of the universalising of forms of partnering in terms of ecological concerns.  I must say that putting an ecological twist to the topic of gay marriage had never really occurred to me.  Upon further consideration, it turns out that an understanding of this way of looking at things, comes from the perspective of an understanding of what is in fact our "place of being".  In other words, we are on a finite planet, whose dimensions are measurable, whose contents have been ascertained for the most part, though of course as our technologies become more invasive and particular, we become more aware of that had previously been unapproachable, or exploitable.  So that, when you focus on ethical/moral "contents" of our "place of being", the concept of ecology becomes one of definition of realities, with the goal of examining the possibilities of societal relationships and how they can be exploited for, one supposes, the greater good of mankind. 
This is, I assume a conservative approach to ecology:  reinforcing the reality of finiteness in our world.
I'm not sure I disagree with this position, though I would submit that while there is no doubt as to the finiteness of objective reality to this planet, in the same way that we are, by means of technological improvements, able to access with greater specificity and discreteness, the possibilities inherent in the objective potentialities of core materials, so also can we say that within the potentialities of societal relationships there are, beyond the traditional means of preserving the species, ways of allowing the experience of human intercourse so as to maximise the applicability of virtue - ethical and moral - and eventually universalize sustainable, peaceful, and meaningful relationships.
The point here, is it seems to me is to find those possibilities to minimise paths of difference by allowing all to find "a place of being".  There then would be the full understanding of ecology:  the fruitful engaging of all in a sustainable environment for the mutual benefit of all.
