(From thetechherald.com) – The burgeoning growth of jellyfish populations throughout the world”s oceans has been linked to global warming, overfishing of natural predators and an increase in pollution which has depleted oxygen in coastal waters, say Spanish scientists.
Researchers at the Institute of Marine Sciences at the National Research Council in Barcelona have said the increase in jellyfish numbers from Spain to Australia, Japan and Hawaii is a sign of the declining health of the world’s oceans.
The scientists blame the overfishing of natural predators of the jellyfish such as tuna and sharks, pollution and a warming of the world’s oceans partly due to global warming as the cause for the increase in numbers.
