More environmental problems in our oceans, this time from aliens.Forget little green men and think on the lines of species ranging from "giant jellyfish and toxic seaweed to muscle-bound mussels and oysters" according to this week's New Scientist (alas subscription required for full article). These invasive species are being transported by ocean going container ships and causing up to $120 billion per year of damages!
But the end of the article also says there are things that can be done to slow further spreading - such as more regular cleaning and destroying any organisms in ballast water before its discharge.
Seems like a very good idea to me.
Also there was this article about the extinction danger to amphibians - the cause has been identified and its loss of habitat. Give those frogs some space!
