More doom and gloom?

When I look over this blog, very little of it appears pleasant. A large proportion of it sounds like doomsday warnings - our oceans are getting worse and we are going to suffer.

Well, why stop that now? A new report has come out which sounds fairly terrifying - scientists are claiming there is a possibility the oceans may run out of oxygen. Hmm.

Our oceans are developing areas called 'dead zones'. These are areas which have lost oxygen, and therefore the organisms living in that area, sadly die out. It is thought that around 15% of our oceans are currently labelled dead zones, but scientists have so far been unsure whether global warming is having any effect on the oxygenation of the water. However, new research suggests that there may be a link between the two. In fact, it’s even more worrying than that, because scientists have determined that speed is a factor in oxygen decrease as well. Therefore, the faster the ocean warms, the larger the zone of deoxygenation, meaning that the impact of global warming could be even more devastating that we already thought.

So more scary news about our big blue. Maybe I should stick to posting cute sea animals instead?
