"Earth is rapidly headed toward a catastrophic breakdown if humans don't get their act together, according to an international group of scientists."
First question: Is this really news? People have been saying thsi stuff for a while now, and it's increasingly common. Also, what are these scientists themselves going to do about it? In many ways, scientific advancements are the cause of this mess, so they should certainly have more ideas. All allegations of hypocrisy and alarmism aside, that is still true in principle.
