Cute Climate Warriors!

According to a new study by researchers from the University of California, Santa Cruz, sea otters play an important role in helping the coastal seaweed forests absorb as much carbon dioxide as possible.

The little furry creatures are natural predators to sea urchins, which in turn like to munch on kelp, a very common family of large seaweeds.

According to the study, which looked at 40 years of data on sea otters and kelp blooms from Vancouver Island to the western edge of Alaska's Aleutian Islands, when sea otters are around, underwater kelp forests can absorb 12 times more carbon dioxide than when the plants aren't protected from urchins (those spikey little devils!).

More otters mean more kelp and since the plant is particularly good at capturing carbon through photosynthesis, this also could mean less CO2 in the atmosphere. [...]

The authors acknowledge that otters probably aren't the answer to rising CO2 levels, a major contributing factor to global warming, but the researchers say their study illustrates the impact animals can have on the atmosphere.

"Right now, all the climate change models and proposed methods of sequestering carbon ignore animals. But animals the world over, working in different ways to influence the carbon cycle, might actually have a large impact," UC Santa Cruz professor Chris Wilmers, a co-author of the study, said in a statement. "If ecologists can get a better handle on what these impacts are, there might be opportunities for win-win conservation scenarios, whereby animal species are protected or enhanced, and carbon gets sequestered."

That's a very good point. For our climate models to be more accurate, the impact of various animal populations should be accounted for (as much as possible), and this could even give more weight to the argument for conservation and the reintroduction of animals in certain ecosystems.

Sea otters in themselves might not have the biggest impact on the carbon cycle, but I'm sure there are many other species that do similar things, and when you add all of them together, you probably get a pretty big impact.(Source)
