WTF Fun Facts 12706 – Oxygen From The Ocean

It’s easy to think all our oxygen comes from trees on land – and a LOT of it does (especially rainforests, which there are lots of, and which need protection). But, in fact, most of it comes from the oceans.

That’s a bit harder to believe, but that doesn’t make it less true.

Plankton, specifically phytoplankton, produce most of the Earth’s oxygen. It also serves as food for sea creatures, but they don’t do much else that makes them interesting to most people. They just float around, completely at the mercy of the currents. They’re green and cruddy and you might even look at them and think “eww.”

And that’s fine since they also can’t be offended.

Here’s the deal: even though oceanic phytoplankton isn’t nearly as pretty as trees, it does similar work for us. These little organisms mostly float along the surface of the water or the upper part of the ocean where light still penetrates. They require sunlight to live and grow and produce food for other ocean creatures. They contain chlorophyll to capture the sunlight. If you remember back to grade school science, you probably see where this is going – photosynthesis.

Our oceanic phytoplankton turns the energy from sunlight, as well as carbon dioxide, and mineral salts partly into oxygen. There’s a lot of other stuff going on there too (other byproducts of photosynthesis, like the sugar they feed on), but oxygen is the byproduct we care about at the moment since we need it to breathe.

The cool thing is that even if you don’t live anywhere near an ocean, you still get the benefits because of the way the planet works. Oxygen is great because it just fills the atmosphere and doesn’t need to be shipped via trucks and planes to far-off destinations.

Scientists estimate that 50-80% of the oxygen production that takes place on Earth comes from the ocean. That’s a big range, but even if you go with the more conservative number, it’s clear that we can’t live without them. However, a lot of that oxygen also goes back into the ocean for other ocean life that needs it.

Don’t get us wrong, we love rainforests and regular trees too. But phytoplankton is doing more work than other flora when it comes to keeping breathing creatures alive.

We can do things like track plankton and get some readings off them, but it’s hard to know exact numbers of what they’re producing at any given time. The amount of oxygen they give off can change with the time of day or the time of year. It can also change depending on how healthy the oceans are.

One problem is that things like dead and decaying plants and animals in the ocean also consume oxygen when they decompose. That’s just one reason why killing off aquatic life (such as coral reefs) can be bad for us.

But if you remember one thing, it should be that these tiny, single-celled creatures do a lot of work for us by not only producing oxygen but by absorbing some of the CO2 we emit.

Some people call them “the lungs of the sea.” – WTF fun facts

WTF Fun Fact 12702 – A North American Hydrangea

There are nearly 75 species of hydrangea (depending on who you ask) and most hydrangeas are native to Asia. In fact, we once thought all hydrangeas were Asian natives until 1910.

As the story goes, Harriet Kirkpatrick, a wealthy woman from Illinois, was out on horseback one day when she discovered a wild hydrangea along a wooded trail. Known to indigenous Americans, no one else had been aware of it. It’s the variety we know refer to as the “Annabelle” hydrangea (Hydrangea arborescens), also called a “smooth” hydrangea.

As far as we know, Kirkpatrick is responsible for the propagation of the flower since she came back later, dug it up, planted it on her property, and began to share it with her friends.

According to Fairfax Master Gardener Ray Novitske, Kirkpatrick was an artist:

“Kirkpatrick’s ceramics were known for utilitarian and ceremonial presentation pottery
(mostly ceramic pigs) throughout the 18th and 19th centuries. Pottery manufacturing at this time was usually located where the clay and the railroads met, and geologists reported that some of the finest clay for pottery was found in and around Anna. This became a natural
place for pottery. Today the Kirkpatrick’s Anna Pottery pieces have found their way to museums and collectors. With its successful business, the family was wealthy so it could participate in leisure activities such as horseback riding.”

The rest of the Annabelle hydrangea’s story, including its name, comes fifty years later when it was “brought to the attention of J.C. McDaniel, famous plantsman and professor of horticulture. He loved it and set the wheels in motion for it to become a commercial success. Two years later, after some nursery propagation and further investigation, it was introduced to the world. McDaniel first wanted to register the hydrangea as “Ballerina”…but a name was selected to honor the belles of Anna who discovered it.” – WTF fun facts

WTF Fun Fact 12605 – The Voice of Bambi

When Donnie Dunagan joined the Marines, he was eager to keep his past a secret. And he managed to do it for his entire 25-year military career.

That secret? As a child, he had a brief stint as an actor, and one of his roles was a voiceover for Disney’s Bambi! The film was released in 1942.

Drafted in 1952 during the Korean War, over the course of his career, Dunagan was promoted 13 times in 21 years (a Marine Corps record). He was also awarded two awards for Valor in Combat as well as the Purple Heart.

When interviewed by his wife, Donna Dunagan, for a Story Corps podcast, he described how closely he held the secret:

“I never said a word to anybody about Bambi, even to you. When we first met I never said a word about it. Most of the image in people’s minds of Bambi was a little frail deer, not doing very well, sliding around on the ice on his belly.”

As a boot camp commander, he was responsible for overseeing hundreds of recruits as well as the drill instructors. He recalled: “I just thought to myself, ‘I don’t think I want all these young Marines to start calling me Major Bambi.’ And I kept my mouth shut.”

The first military colleague to find out was a fellow Marine he had worked and fought for. The secret was uncovered after a personnel audit. Dunagan explained:

“He called me in at five-thirty in the morning, I will never forget it. I go in his office and he says, ‘Dunagan! I want you to audit the auditors.’ I never said a disrespectful word to this man in twenty years, I said, ‘General, when do you think I’m going to have time to do that?’ Then he looked at me, pulled his glasses down like some kind of college professor. And there’s a big, red, top-secret folder that he got out of some safe somewhere that had my name on it. He pats this folder, looks me in the eye, and says, ‘You will audit the auditors. Won’t you…Major Bambi?’”

It turns out Dunagan was right – that’s exactly what he would have been called had he let it slip during his fighting career! – WTF fun facts
