It was recently dragged for plankton by scientists, and they found six times as much plastic as plankton.

They're also harmless plankton feeding animals.

Talk about more plastic bags than plankton.

But since we ate all the oysters and we ate all the fish that would eat the plankton, there's nothing to eat the plankton and there's more and more of it, so it dies of old age, which is unheard of for plankton.

It is the big cats, and it's the plankton.

It's extremely clear water, because there's hardly any plankton.

That's bad news for coral reefs and oxygen producing plankton.

It might be a change in the distribution of plankton.

Then the plankton feeders, these little damselfish, the little animals floating in the water.

Now, how do we analyze samples like this one that contain more plastic than plankton?

And the black rock is the sediment on the sea bottom in the absence of plankton.

This is some shot, by Dr. Mike Latz at Scripps Institution, of a dolphin swimming through bioluminescent plankton.

I showed him and Maria a zooplankton trawl from the gyre north of Hawaii with more plastic than plankton.

It runs down the rivers, and it feeds the plankton, the little microscopic plant cells in the coastal water.

The dolphins eat the fish that have PCBs from the plankton, and those PCBs, being fat soluble, accumulate in these dolphins.

And yet, if you look at whale sharks, which is the other plankton eating large shark, its diversity is much greater.

In 2002, in the central Pacific gyre, there were found to be six kilograms (kg) of plastic for every kilogram of plankton near the surface.

And it's been suggested that basking sharks would make fantastic indicators of climate change, because they're basically continuous plankton recorders swimming around with their mouth open.

But just to try to prove that fact to you, I've brought along some bioluminescent plankton in what is undoubtedly a foolhardy attempt at a live demonstration.

So, if we could have the lights down and have it as dark in here as possible, I have a flask that has bioluminescent plankton in it.

And they are thought to be able to filter a cubic kilometer of water every hour and can feed on 30 kilos of zoo plankton a day to survive.

And fertilizers and pesticides are flowing into the bay from the golf course the pesticides killing all the larvae and little animals, fertilizer creating this beautiful plankton bloom and there's your pea soup.

We see the base of the food chain, the plankton, the small things, and we see how those animals are food to animals in the middle of the pyramid, and on so up this diagram.

And sometimes you can see it even closer than that, because the heads on ships that's toilets, for any land lovers that are listening are flushed with unfiltered seawater that often has bioluminescent plankton in it.

And in the spring, when the sun returns to the ice, it forms the phytoplankton, grows under that ice, and then you get bigger sheets of seaweed, and then you get the zoo plankton feeding on all that life.

The chalk itself's composed by plankton which has fallen down from the sea surface onto the sea floor, so that 90 percent of the sediment here is skeleton of living stuff, and then you have that millimeter thick red layer, and then you have black rock.

At the same time, the material brought back from land to sea include nutrients and trace elements that cause a boom among plankton, which in turn feed other marine biota. Locally, but sometimes still at a grand scale, the shock waves cause major sediment slides on steep underwater slopes such as those of the continental shelves.
