| However some scientists say that the boom in blooms is down to a natural cycle that over the course of 20 years or so sees the rapid growth and die-off of jellyfish. | However some scientists say that the boom in blooms is down to a natural cycle that over the course of 20 years or so sees the rapid growth and die-off of jellyfish. |
