Jellyfish threaten to 'dominate' oceans
This article talks about how the oceans could be filled with sumo wrestler sized jelly fish. Apartently we are eating so many fish that we have changed the ecosystem. Allowing Jellyfish to take over as the most common sea creature. And to make it worse areas that are really polluted can support jellyfish life but not regular fish life.
That’s fine. We can eat Jellyfish sushi and then wipe them out too and balance will once again be restored!
