Connected to every problem that faces the world, there are infinite possibilities for positive, sustainable change. Rather than a) sticking to business as usual or b) kvetching non-stop, why don't we grasp some of these possibilities? Do something, change something, make the world a better place.

![Plankton decline across oceans as waters warm
The decline - about 1% per year - could be ecologically significant as plankton sit at the base of marine food chains.
This is the first study to attempt a comprehensive global look at plankton changes over such a long time scale.
“What we think is happening is that the oceans are becoming more stratified as the water warms,” said research leader Daniel Boyce from Dalhousie University in Halifax, Nova Scotia, Canada. This is the first study to attempt a comprehensive global look at plankton changes over such a long time scale.

If the trend is real, it could also act to accelerate warming, the team noted.
Photosynthesis by phytoplankton removes carbon dioxide from the air and produces oxygen.
In several parts of the world, notably the Southern Ocean, scientists have already noted that the waters appear to be absorbing less CO2 - although this is principally thought to be because of changes to wind patterns - and leaving more CO2 in the air should logically lead to greater warming.
“Phytoplankton… produce half of the oxygen we breathe, draw down surface CO2, and ultimately support all of our fisheries,” said Boris Worm, another member of the Dalhousie team.
