Well, "biggest" is something else than "urgent and important". Fair enough, though. It perhaps is true that climate change is assigned undue importance in public discourse when compared with other problems that might be just as important - or even more so. You'd be hard pressed, however, to find an issue that has as many immediate (or near-future) and potentially severe repercussions for as many people. Evolutionary divergence certainly seems like a potentially relevant future problem, the key word here being "potentially", though. Climate change, on the other hand, is a certain reality. Assigning the same resources to both problems, even though one of them might never even materialize (or do so in a manner we can't even anticipate yet), therefore would be irrational. That doesn't mean, however, that we can't work on solving both at the same time. At the very least, 8 billion or so people allow for massive parallelism.
