|My jellyfish/storm/world paperweight|
"It probably sounds ludicrous if you are hearing this for the first time - how could jellyfish take over the oceans?
But like the old joke, "How do you eat an elephant? ... One bite at a time, " jellyfish are taking over from fish, one bite at a time.
A bite of fish larvae here, a bite of fish eggs there ... a bite here and there of plankton that the larvae would eat.
The cumulative effect of any one of these perturbations are enough to "flip" an ecosystem to a state of jellyfish control.
But in many cases around the world, these perturbations are acting in concert.
And like a symphony, where each instrument plays a special note but together they produce something bigger than the sum of their parts, these perturbations in combination produce ecosystem damage that, in many cases, is well beyond the sum of its parts.
I stated in the introduction that we are led to believe that if we just stop over-fishing, that the fish will come back, and if we just stop polluting, then nature will cleanse itself.
Our observations in many ecosystems around the world now tell us that this is just not so."
