I'll give you one really quick example. The mountain pine beetle is often pointed to as a wholly negative force in terms of what it's going to do to the forestry industry. It's also creating an opportunity to make ethanol out of wood waste, which wasn't there before.
So even in the darkest rain clouds, there are some silver linings. That's one I would point to, and there are many others. But it's a fact of life, and trying to find the opportunities within those changes is going to happen.
