In 2005, trees outnumbered people 61 to 1. In 2015, it's 422 to 1. Here's what changed.

Trees are some of the most helpful organisms on earth.

One large tree can supply a day's worth of oxygen for four people. They also absorb carbon dioxide, provide homes for animals, and make the nitrogen cycle happen, not to mention the whole "food and goods for human consumption" thing. No doubt about it, trees are pretty good at what they do.

And a new study revealed there are even more trees on Earth than we thought. A whole lot more.

The researchers found that there are over 3 TRILLION trees on Earth. That works out to be around 422 trees per person. Congrats, you just got yourself a tiny forest.

This is a huge deal, considering the previous tree tally, conducted in 2005 by Evergreen State College in Washington, only used NASA satellite imagery and found just 400 billion trees, which averaged out to a scant 61 trees a person.

To arrive at that number, an international team of scientists combined two common methods: satellites and manually counting tree trunks.

You read that right. One of the most accurate ways for scientists to count trees is to actually go trunk-by-trunk and count them.

The team, led by Dr. Thomas Crowther, an ecologist at the Netherlands Institute of Ecology who conducted the research while working at Yale University, first gathered the results of on the ground tree counts from every continent except Antarctica.

The various counts covered about 430,000 hectares (1,062 acres) worldwide, which may not sound like much, but when combined with satellite imagery, it gave the team a better estimate about the density of the forests and allowed them to make a more accurate count of the total number of trees on the planet.

Why is the tree count so important? It all comes back to conservation.

"It's not like we've discovered a load of new trees; it's not like we've discovered a load of new carbon," Crowther told BBC's "Science in Action."

"We're simply describing the state of the global forest system in numbers that people can understand and that scientists can use, and that environmental practitioners or policymakers can understand and use."

And hopefully, they will.

Between poor forest management practices, deforestation, and land-use policies, humans have had a majorly negative impact on tree populations around the globe.

Crowther's team estimates the number of trees has decreased 46% since the dawn of human civilization.

While a more accurate count is great news, we're also not out of the woods yet.

As much as we all love trees, paper still makes up the largest percentage of municipal solid waste.

On average, the world uses an estimated 27,000 trees each day in toilet paper alone. And we're not much better when it comes to paper towels. They make up an estimated 20 to 40% of waste from dorms and office buildings.

Knowing and understanding the tree count is the first step to saving these rapidly diminishing resources and developing sustainable solutions.

But there are still plenty of things you can do to help Earth's tree population grow and thrive.

And you don't have to replant billions of trees to do your part.

Start by choosing paper made from recycled material or from sustainable forests. Say no to paper and plastic at the store and bring a reusable bag. Even reducing your font one size before printing is a small change that can have a big impact.

Making smart choices about the products we use and our personal habits may help spare our forests.

Because we may have 3 trillion trees on Earth, but we need every last one.

You can hear from Crowther himself, as he shares his method and findings in this short video from Yale University's School of Forestry and Environmental Studies:

We're redefining what normal means in these uncertain times, and although this is different for all of us, love continues to transform us for the better.

Love is what united Marie-Claire and David Archbold, who met while taking a photography class. "We went into the darkroom to see what developed," they joke—and after a decade of marriage, they know firsthand the deep commitment and connection romantic love requires.

However, their relationship became even sweeter when they adopted James: a little boy with a huge heart.

In the United States alone, there are roughly 122,000 children awaiting adoption according to the latest report from the U.S Department of Health and Human Services. While the goal is always for a child to be parented by and stay with their biological family, that is not always a possibility. This is where adoption offers hope—not only does it create new families, it gives birth parents an avenue through which to see their child flourish when they are not able to parent. For the right families, it's a beautiful thing.

The Archbolds knew early on that adoption was an option for them. David has three daughters from a previous marriage, but knowing their family was not yet complete, the couple embarked on a two-year journey to find their match. When the adoption agency called and told them about James, they were elated. From the moment they met him, the Archbolds knew he was meant to be part of their family. David locked eyes with the brown-eyed baby and they stared at each other in quiet wonder for such a long time that the whole room fell silent. "He still looks at me like that," said David.

The connection was mutual and instantaneous—love at first sight. The Archbolds knew that James was meant to be a part of their family. However, they faced significant challenges requiring an even deeper level of commitment due to James' medical condition.

James was born with congenital hyperinsulinism, a rare condition that causes his body to overproduce insulin, and within 2 months of his birth, he had to have surgery to remove 90% of his pancreas. There was a steep learning curve for the Archbolds, but they were already in love, and knew they were committed to the ongoing care that'd be required of bringing James into their lives. After lots of research and encouragement from James' medical team, they finally brought their son home.

Today, three-year-old James is thriving, filled with infectious joy that bubbles over and touches every person who comes in contact with him. "Part of love is when people recognize that they need to be with each other," said his adoptive grandfather. And because the Archbolds opted for an open adoption, there are even more people to love and support James as he grows.

Cats are notoriously weird. Everyone who's had cats knows that they each have their own unique quirks, idiosyncrasies, preferences, habits, and flat-out WTFness.

But even those of us who have experience with bizarre cat behavior are blown away by the antics this "cat dad" is able to get away with.

Kareem and Fifi are the cat parents of Chase, Skye, and Millie—literally the most chill kitties ever. They share their family life on TikTok as @dontstopmeowing, and their videos have been viewed millions of times. When you see them, you'll understand why.

Take Chase's spa days, for example. It may seem unreal at first, but watch what happens when Fifi tries to take away his cucumber slices.

When she puts them back on his eyes? WHAT?! What cat would let you put them on once, much less get mad when you take them off?

This cat. Chase is living his best life.

But apparently, it's not just Chase. Skye and Millie have also joined in "spaw day." How on earth does one couple end up with three hilariously malleable cats?

Oh, and if you think they must have been sedated or something, look at how wide awake they are during bath time. That's right, bath time. Most cats hate water, but apparently, these three couldn't care less. How?

They'll literally do anything. The Don't Stop Meowing channel is filled with videos like this. Cats wearing glasses. Cats wearing hats. Cats driving cars. It's unbelievable yet highly watchable entertainment.

If you're worried that Kareem gets all the love and Fifi constantly gets the shaft, that seems to be a bit for show. Look at Chase and Fifi's conversation about her leaving town for a business trip:

The whole channel is worth checking out. Ever seen a cat being carried in a baby carrier at the grocery store? A cat buckled into a car seat? Three cats sitting through storytime? It's all there. (Just a heads up: A few of the videos have explicit language, so parents might want to do a preview before watching with little ones.) You can follow the couple and their cats on all their social media channels, including Instagram and YouTube if TikTok isn't your thing, here.

If you weren't a cat person before, these videos might change your mind. Fair warning, however: Getting a cat because you want them to do things like this would be a mistake. Cats do what they want to do, and no one can predict what weird traits they will have. Even if you raise them from kittenhood, they're still unpredictable and weird.

And honestly, we wouldn't have them any other way.

You know that feeling you get when you walk into a classroom and see someone else's stuff on your desk?

OK, sure, there are no assigned seats, but you've been sitting at the same desk since the first day and everyone knows it.

So why does the guy who sits next to you put his phone, his book, his charger, his lunch, and his laptop in the space that's rightfully yours? It's annoying!

There have been many iconic dance routines throughout film history, but how many have the honor being called "the greatest" by Fred Astaire himself?

Fayard and Harold Nicholas, known collectively as the Nicholas Brothers, were arguably the best at what they did during their heyday. Their coordinated tap routines are legendary, not only because they were great dancers, but because of their incredible ability to jump into the air and land in the splits. Repeatedly. From impressive heights.

Their most famous routine comes from the movie "Stormy Weather." As Cab Calloway sings "Jumpin' Jive," the Nicholas Brothers make the entire set their dance floor, hopping and tapping from podium to podium amongst the musicians, dancing up and down stairs and across the top of a piano.

But what makes this scene extra impressive is that they performed it without rehearsing it first and it was filmed in one take—no fancy editing room tricks to bring it all together. This fact was confirmed in a conversation with the brothers in a Chicago Tribune article in 1997, when they were both in their 70s:

"Would you believe that was one of the easiest things we ever did?" Harold told the paper.

"Did you know that we never even rehearsed that number?" added Fayard.

"When it came time to do that part, (choreographer) Nick Castle said: 'Just do it. Don`t rehearse it, just do it.' And so we did it—in one little take. And then he said: 'That's it—we can't do it any better than that.'"
