changing the odds some

The writer, environmentalist and founder of 350.org, Bill McKibben, tells Greenpeace that he's mostly given up being optimistic or pessimistic.

'Our odds are not incredibly good of success, but I wake up every day saying "What can I do to change the odds some?" It's not impossible the task that we have. We're not going to stop global warming, but slowing it to the point where we can cope with it, remains within the realm of possibility.'
