He pointed at the algae.

Offshore Membrane Enclosures for Growing Algae.

And the fish have grazed the algae, so the turf of algae is a little lower.

And the algae give the corals sugar, and the corals give the algae nutrients and protection.

Our research covered the biology of the system, which included studying the way algae grew, but also what eats the algae, and what kills the algae.

Caulerpa taxifolia, the so called killer algae.

The things on the ground are algae.

This one disguises itself as floating algae.

Watch him blend right into this algae.

So this, for example, is hydrogen generating algae.

And it's covered with algae. That's what happens.

Algae thrived in the extreme heat, poisoning the water.

I know, dude, the algae, the phytoplankton, the relationships

Here's some algae in the foreground and an octopus.

There's no coral, algae growing on it, and the water's pea soup.

But when it gets too hot, the algae can't make the sugar.

Biofuels Photosynthetic Algae Compost All those ideas have one thing in common.

The algae are not going to suffocate because of CO2, as we would.

I floated through the world of plankton, searching for tiny algae to eat.

The first is that we have fossils of algae from 3.5 billion years ago.

Rivers washed sediment into the seas, until the organic remains of the algae were buried.

In Fiji, they have iridescent algae that come out once a year in the water.

They believe in wind and the sun. Exxon is talking about growing algae, all kinds of alternatives.

The waste water that leaks out is water that already now goes into that coastal environment, and the algae that leak out are biodegradable, and because they're living in waste water, they're fresh water algae, which means they can't

Maybe there is a little bit of oxygen from some algae on the beach not far from here.

My fellow plankton came in all sizes, from tiny algae and bacteria to animals longer than a blue whale.

Most of the biomass is low on the food chain, the herbivores, the parrotfish, the surgeonfish that eat the algae.

Fungi married algae ... clinging to rock, and eating it too ... transforming barren land. True land plants arose, leafless at first.

This is the Mediterranean coast with no fish, bare rock and lots of sea urchins that like to eat the algae.

We basically take waste water with algae of our choice in it, and we circulate it through this floating structure, this tubular, flexible plastic structure, and it circulates through this thing, and there's sunlight of course, it's at the surface, and the algae grow on the nutrients.

After a few years, between five and seven years, fish come back, they eat the urchins, and then the algae grow again.

Tadpoles keep waterways clean by feeding on algae, reducing the demand on our community's filtration systems and keeping our cost of water low.

Now, we grew algae in waste water, and we built tools that allowed us to get into the lives of algae so that we could monitor the way they grow, what makes them happy, how do we make sure that we're going to have a culture that will survive and thrive.

Most of us don't have fungi or algae in our brains, so what is our brain going to do if we put that in?

It accepts algae and detritus in one end, and through this beautiful, glamorous set of stomach organs, out the other end comes cleaner water.

There's one last elephant in the room, the proteins themselves, which come from algae and bacteria and fungi, and all over the tree of life.

The algae that grow produce oxygen, as I've mentioned, and they also produce biofuels and fertilizer and food and other bi algal products of interest.

Here we're going to see one backing into a crevice, and watch his tentacles he just pulls them in, makes them look just like algae.

We end up with things we've heard about before red tides, for example, which are blooms of toxic algae floating through the oceans causing neurological damage.

And where the diver is, this is probably where most of the reefs of the world are now, with very few corals, algae overgrowing the corals,

Even the most extreme animals fight for survival, and only cold adapted organisms survive there, including many types of algae, animals, bacteria, fungi, plants, and protista.

Lavender, Mugwort, poppy seed, grape juice, chlorella, spirulina, blue green algae, iodine, zeolite, ginseng, bentonite clay, chlorophyil, cilantro, honey, coconut oil, hemp seeds, seaweed, and noni juice.

The whole animal world today lives on a stockpile of bacterial oxygen that is cycled constantly through plants and algae, and their waste is our breath, and vice versa.

Most of the reefs are dead, most of the corals are dead overgrown by algae and most of the fish are smaller than the pencils we use to count them.

They of course use solar energy to grow, and the wave energy on the surface provides energy for mixing the algae, and the temperature is controlled by the surrounding water temperature.
