When Biodiversity IS the problem and not the solution...
Globalization is all great until the visitors are fish (and other) species that do not belong in the ecosystems where you are
You have to think that the more species a region has, the better stuff is, right? The Amazon, for example, is said to be the most bio-diverse region of the world, and indeed it does have more creatures and plants than the world's scientists can type or imagine. But recent studies are showing it's not nearly as old as it might be thought, and ancient ruins found deep in the jungles indicate vast agricultural activities there not so long ago.
Anyway, scientists do not know what scientists think they know, and we cannot help but think that any industry - scientific or otherwise - that depends on grant money to survive is gonna say whatever they have to say to grab as much of said grant money as they can get their clippers on or their microscopes (are there still microscopes?) looking at closely.
Even beautiful tropical fish like this Cocoa Damselfish can be bad for the environment if they came from far away and invade existing ecosystems.
This is a story from The Independent about Malta and talks about the invasion of a wide arrange of species - such as the incredibly beautiful Cocoa Damselfish - that's a result of connections between different places in the world. The unforeseen impact of globalization:
Through globalisation, the increasing introduction of alien species is fast becoming one of the major pressures on biodiversity and ecosystem functioning, with consequences on the goods and services that native species uniquely provide in different parts of the world.
