I live in Israel I'm active in all of green orgs and things . I have a blog on climate change "The Black Butterfly Effect אפקט הפרפר השחור"
The phenomenon whereby a small change at one place in a system can have large effects elsewhere, a butterfly flapping its wings in Rio de Janeiro might change the weather in Chicago http://wordnet.princeton.edu/perl/webwn Today We already released 500 billion tons of Carbon to the atmosphere that is a very huge butterfly!
