And when is that going to happen ? I must put it in my diary .
If an asteroid hits us , I think we might have a few more problems than a dust cloud .
And that's the beauty of moving away from coal and oil . We can still use those resources in products that we can recycle and the bonus is that the reserves we have left will be there for such ' emergencies '.
Not much good to us if the asteroid hits just after we've used it all .
