But maybe that would buy enough time for other parts of the equation to shift... It seems to me that we humans tend to change things up faster than our environments can keep up, but our environments do eventually change.

Maybe if we are part of a process that lowers the number of Jellyfish, another part of the equation will surface to help: Natural predator, loss of needed food/fuel for Jellyfish, etc.

We are always having to adapt to changing circumstances, this may help solve the immediate problem and may give us time to face the changing environment of the future.

I do not think humans can ever do anything that would be considered perfect on all fronts...
