What Steffen meant by "On the one hand we have the unthinkable, and on the other hand we have the unimaginable" is:
There are worst-case scenarios which are as a result of the planet depletion. These effects are known to be unthinkable. Then the alternative is the unimaginable which is something we are yet to know. The environmentalists are working towards the unimaginable but are yet to grasp it. Whereas as the planet experiences a downward trend then the unthinkable is what will happen.
