The idea that we're doomed didn't really sink in until a few weeks ago when I learned about this awful bit of chemistry which basically means in 40-100 years if we continue on our current track, the Amazon rainforest, Canadian forests and Siberian forests will all begin to emit more CO2 than they take in.
So in short, we probably are doomed, unless a dramatic restructuring of our society takes place in the next few decades. The likelihood that this change will be peaceful or not disruptive to our current way of life is non existent unless we just suddenly get really cozy with nuclear reactors
My only solace is that the evil bastards who are fully aware this is happening and yet continue to expand their cancerous industries are human. They have names, addresses, fears, hopes, families, all things we can use to CONVINCE them of the error of their ways. Likewise, global capitalism HAS the resources to address this crisis in the remaining window, it IS still, barely, a matter of poltical will.
We are the last generation that will have this choice.
So yeah, we're fucked.
