Opportunity

"Invasive" carp have "taken over" the Mississippi River system.  That seems a general consensus.

There are a few ways to look at it:

• "Disastrous" or "horrible"
• "Exciting" or "interesting"

Either way, a huge opportunity exists for whichever species changes or moves to make the most of the "opportunity".

We may or may not understand the big "explosions" in life's history... backward.
