Sharon Astyk wrote a fantastic offering several days ago, on the importance of Christian Environmentalism
Everyone should read it, whether Christian or not, Socially aware or not, Steward of Creation...or not.
We all have vision of a future, and we can all benefit by dialoging about our visions. One trouble with us as a species is that when we only listen to those with whom we already agree (or think we should agree, even if secretly we don't) then we start to develop a language of our own, that others don't understand. And we don't know that others don't understand! Because everyone we hang out with, whether we hang at church, or political rallies, or on certain forums on the internet; well, they all speak and understand the same language we do.
Do yourself a favour, do your children a favour. Give it a read with an open heart.
