Thirty pieces of silver is about right.  Destroying the world out of greed and hubris is low and stupid on a cosmic scale. The Bible has some very interesting things to say about the "desolation" of the earth in the end times, things that look remarkably like what is occurring in the world now, with storms in the sea that cause men to faint in terror; with mass die-offs of animals including the birds in the air, the beasts in the fields, and even the fishes in the seas; a time when "knowledge will increase" and the people will "go to and fro" (be highly mobile); a third of the trees will burn; and other things equally eerie.   

It's nice to see a Christian perspective that includes respect for the creation, something sorely lacking in most Christians because it isn't taught.  When a person puts these things together with Jesus' teachings on how to live, it's pretty obvious to me that we don't live with the world as we should, and as we need to, for sustainability.
