Go and read this excellent essay "Beyond the point of no return" by Ross Gelbspan posted over at Gristmill. I think he has managed to crystallize the essence of everything I have been trying (or wanting) to say here at planet doom? (in an admittedly much more scattershot way) in his post. A few excerpts:
We have failed to meet nature's deadline. In the next few years, this world will experience progressively more ominous and destabilizing changes. These will happen either incrementally -- or in sudden, abrupt jumps.
This slow-motion collapse of the planet leaves us with the bitterest kind of awakening. For parents of young children, it provokes the most intimate kind of despair. For people whose happiness derives from a fulfilling sense of achievement in their work, this realization feels like a sudden, violent mugging. For those who feel a debt to all those past generations who worked so hard to create this civilization we have enjoyed, it feels like the ultimate trashing of history and tradition. For anyone anywhere who truly absorbs this reality and all that it implies, this realization leads into the deepest center of grief.
To keep ourselves afloat, we need to change the economic and political structures that determine how we behave. In this case, we need to elevate the ethic of cooperation over the deeply ingrained reflex of competition. We need to elevate our biological similarities over our geographical differences. We need, in the face of this oncoming onslaught, to reorganize our social structures to reflect our most humane collective aspirations.
