This is my jam.
Pamela Kirkland
Glad to hear it, Ryan. It's the official theme song of Earth Day.
Ryan Willard
Whoa. Earth Day has a theme song?
Ryan Hickman
Of course.
Pamela Kirkland
It's one of the biggest worldwide celebrations.
Ryan Willard
I love starting the show with a song.
Pamela Kirkland
Me too. I'm Pamela Kirkland.
Ryan Willard
And I'm Ryan Willard. It's Wednesday, April 26th.
Pamela Kirkland
This is the 10 News.
Ryan Willard
10, 9, 8, 7, 6, 5, 4, 3, 2, 1. This past Saturday, April 23rd, was Earth Day. Earth Day began in the US in 1970, but is now spread around the world. Around 1 billion people celebrate Earth Day each year.
Pamela Kirkland
It all started when Wisconsin Senator Gaylord Nelson saw the terrible effects of an oil spill off the coast of California in 1968. He campaigned for a day to protect the environment. That day became Earth Day.
Ryan Willard
From the beginning, schools and universities have been the driving force behind Earth Day. It's always held around the time students have spring break so that they can participate in this important day. On the First Earth Day, 10% of the US population got involved.
Ryan Hickman
Way to go.
Pamela Kirkland
Earth Day led to the creation of the Environmental Protection Agency, the epa, and the national oceanic and Atmospheric Agency, or noaa, the scientific body that monitors the weather, oceans and atmosphere. Earth Day led to so much good.
Ryan Willard
Absolutely. We had so much to celebrate this Earth Day.
Pamela Kirkland
One of the big things on everyone's mind around Earth Day and every day is climate change and what exactly we can do to slow the effects.
Ryan Willard
Hey, Pamela, we have a guest in the studio.
Pamela Kirkland
Ryan, is that a whole cow?
Ryan Willard
Yep. This is Ernestina. Ms. Lane from Nature Nerds told me about a new way to slow climate change, and it involves potty training cows.
Pamela Kirkland
Uh, let's go to Lane, and let's hope Ernestina is an already potty trained cow.
Ms. Lane
Potty training? The not so glamorous process of teaching people where to put their pee and poop. It's not the most pleasant thing to think about, but we've all gone through it, and our world is a better place because of it. No joke. It takes toddlers anywhere from three to six months to master the porcelain throne. But cows learn where to place their bovine behinds much faster.
Trivia Host
What?
Ms. Lane
Yes, you heard me correctly. Today we're talking about potty trained cattle. According to a recent study, it only takes 15 days for cattle to become bathroom loving bulls and commode using cows.
Ryan Willard
You're kidding me.
Ms. Lane
Now, you might be thinking, why in the world are scientists teaching cows to use the toilet? Well, to save the planet, of course. Okay, you see, cows are big animals. They eat a lot and Drink a lot to sustain their large frames. But when you eat a lot and drink a lot, you poop and pee a lot. Just how much pee are we talking about? Well, a single cow can produce eight gallons of pee a day. Round up five cows and you can fill a bathtub.
Ryan Hickman
That's gross.
Ms. Lane
Cow pee and poo are not inherently bad. However, things get complicated when the scat and the urine unify. You see, the resulting mixture contains a chemical known as ammonia. And when ammonia soaks into the soil, it breaks down and becomes the greenhouse gas nitrous oxide. Though it only makes up 7% of the greenhouse gases in our atmosphere, nitrous oxide is not to be taken lightly. With this in mind, scientists at the University of Auckland came up with a wacky theory for reducing nitrous oxide. Manage the waste proactively by potty training the cattle. First proposed as a joke, the idea eventually became a full blown study involving specially constructed cow toilets called Moo Lo. Now, don't get too excited. The cows were not trained to sit on toilets.
Ryan Hickman
Aw, man.
Ms. Lane
The mulu bears no resemblance to your bathroom at home. Rather, it's a special metal stall with a grated floor covered in fake grass. Scientists conducted the experiment with 16 young cows at an indoor lab in Germany. To begin the study, they brought the calves into the mulu and waited for nature to take its course. Once the cows peed, they were rewarded with their favorite special treat, a molasses milkshake.
Narrator
Delicious.
Ms. Lane
And any cows that released themselves outside of the designated potty training area got a little squirt of cold water. The process was repeated, and after about two weeks, 11 of the 16 cows were entering the mulu to pee without prompting. So the initial study was a smashing success. But what does it all mean? Well, training a handful of cows to pee in a cool box doesn't do our planet much good. But training a lot of cows to pee in special boxes could. Initial estimates from the Auckland study suggest that collecting 80% of cow urine produced on a farm could reduce ammonia emissions by more than half.
Ryan Hickman
Excellent.
Ms. Lane
Those are some pretty sizable numbers. And if scaled globally and implemented correctly, it's possible that potty training cattle could have a considerable positive impact on lowering greenhouse gas emissions.
Narrator
A.
Ryan Hickman
Awesome.
Ms. Lane
But only time will tell if the idea of commode loving cattle and bathroom using bulls makes it into common agricultural practices. Until then, enjoy the fact that you get to use a real toilet instead of the mulu.
Ryan Willard
Thanks, Ms. Lane. Did you hear that, Ernestina? You could help mitigate climate change.
Ms. Lane
Ugh.
Pamela Kirkland
Maybe There'll be a way to train the cows to be a little less farty in the future.
Trivia Host
Woo.
Ryan Willard
That's a stinky one. Did you get into the cheese puffs, Ernestina?
Pamela Kirkland
Ryan, what's the number one easiest way to protect the earth for future generations?
Ryan Willard
Oh, I got this one, Pamela. It's recycling. And we recycled a couple of our segments. Today, 13 year old climate activist Ryan Hickman is making a difference with his company, Ryan's Recycling. SO ten news correspondent Karine Katabayan sat down with him to get the lowdown.
Karine Katabayan
Hey Ryan, thanks so much for joining us. Can you tell us who you are, what you do and why you do it?
Ryan Hickman
My name is ryan Hickman. I'm 13 years old. I like to recycle and I started just when I was three and a half. My dad took me to the local recycling center for the first time. I loved it so much so I want to keep doing it. This is fun. And I saw it was helping the planet.
Karine Katabayan
What is Ryan's Recycling and what does it do?
Ryan Hickman
Yes, I have a recycling company, Ryan's Recycling, based in Southern California, Orange county. And we go to all my customers, we pick up the recycling and we take it to the recycle center and recycle it.
Karine Katabayan
So wait, you basically have customers that you pick up the recycling and then you take it to the center for
Ryan Hickman
them, but they donate to me, so I get all the money from it too and I put that in my college fund.
Karine Katabayan
Very cool. So what does the job entail? Can you walk me through as if I were one of your customers?
Ryan Hickman
So you go on my website, you email my dad. So first I get a donut because they're really good and I can't recycle without them. Go to my customer's house at a call for a pickup, I recycle or I pick up from them, take it to the recycle center, I sort it there and I give the recycling to them to recycle properly.
Karine Katabayan
How do you encourage your friends to recycle?
Ryan Hickman
I just told them it's easy and it helps save the planet. Most of the time they do it too. Like I have beach clubs all the time and I have lots of people that go to them too. Bunch of kids from my school and help me clean up the beach. It's fun, honestly, just tell them it's fun, it helps the planet, it doesn't kill animals. And most kids are excited about it too.
Karine Katabayan
What do you think is the most recyclable item?
Ryan Hickman
Probably either bottle can or glass Because. Or probably. No probably. Can or glass bottle. Cause those could be recycled infinitely indefinitely. Is that the right term? I don't know. A lot of times.
Karine Katabayan
What's the easiest tip that you can give to someone who wants to recycle?
Ryan Hickman
Just start small. You don't have to do it all big like me. Just try your best. Every little bit makes a big difference.
Pamela Kirkland
Thank you, Ryan. Recycling is a great way to help the earth. And don't forget to reduce and reuse as well.
Ryan Willard
Right. There's always a little more we can do.
