Jellyfish takeover questioned
On a luckless fishing trip George Monbiot fears "the beginning of the end of vertebrate ecology":
A combination of overfishing and ocean acidification (caused by rising concentrations of carbon dioxide in the atmosphere) has creating the perfect conditions for this shift from a system dominated by fish to a system dominated by jellyfish.Don't worry George, jellyfish aren't taking over the oceans just yet:
In the last decade, gelatinous blobs have reportedly clogged up water treatment and power plants, overrun fish farms, and hampered fishermen around the world. They even forced the nuclear-powered USS Ronald Reagan out of the Port of Brisbane in 2006.
But claims they will dominate our oceans are not supported by data, says Winthrop Professor Carlos Duarte director of the Oceans Institute at the University of Western Australia.
