This incredible art project in Paris uses heartbeats to plant trees. Here's how.
The Eiffel Tower knows how to go green and looks great doing it.
Plenty of folks have seen the Eiffel Tower.

And it's certainly a sight to see on any occasion.
But until Sunday night, no one had seen it quite like this...

In dazzling fashion, images and graphics were projected onto the tower the day before COP21 began in Paris.
The installation lit up the sky with its forest theme on Nov. 29, 2015, a day ahead of COP21 (that's short for the Conferences of Parties), the United Nations' climate change summit, which runs through Dec. 4.
The project, titled "1 Heart 1 Tree" and created by artist Naziha Mestaoui, is aimed at drawing attention to the conference and encouraging leaders to (wake up and) set ambitious goals to reduce carbon emissions.

The best part? You can be part of Mestaoui's creation.
By downloading an app and using its sensor to monitor your heartbeat, the pumping of your heart will create a growing "branch" on the tower's tree. (How freaking cool is that?!) You can view it in the app on your phone and share with friends on social media.
But that's not all. Through the project's partnered reforestation programs, app users also purchase an actual tree to be planted when they buy a virtual one for the tower. So far, the app has ensured about 50,000 trees will be planted because of "1 Heart 1 Tree."
"I created this installation so that people everywhere can realize what is possible if we come together," Mestaoui said in a speech on Sunday, according to a press release provided to Upworthy.
"We can protect and regrow our forests, we can tap the natural powers of the sun, the wind, the earth and the sea, and we can build a safer future if we go 100% clean energy for everyone."
COP21 is a truly historic event — one that could actually spark a major shift in the fight against climate change.
Leaders from more than 150 countries around the world have gathered in Paris to nail down the specifics as to how each can do its fair share to cut way back on carbon emissions.
It's the largest gathering of heads of state — ever.
The end goal is to reduce the world's collective carbon footprint to ensure global temperatures don't exceed 2 degrees Celsius of what they were before the industrial revolution of the late-1700s. Because, as climate science tells us, that would be absolutely awful.
The conference is just starting but, so far, news out of the summit seems promising.
For starters, take the summit's guest list — (practically) the whole world is seriously committed to fighting climate change. That includes major polluters, like the U.S., India, China, and Russia.
Also, news of Bill Gates' multibillion-dollar initiative to unite the world with clean energy investments is already making waves as a game-changing strategy to make our energy sources greener while also helping eradicate poverty in the developing world.
Basically, it's a huge win-win.
"1 Heart 1 Tree" serves as a powerful reminder that the beauty of art can have an immeasurable impact.
Lighting up The Eiffel Tower won't stop climate change on its own — but it can inspire the hearts and minds of those who are dedicated to trying their best.

Resurfaced video of French skier's groin incident has people giving the announcer a gold medal
"The boys took a beating on that one."
Downhill skiing is a sport rife with injuries, but not usually this kind.
A good commentator can make all the difference when watching sports, even when an event goes smoothly. But it's when something goes wrong that great announcers rise to the top. There's no better example of a great announcer in a surprise moment than when French skier Yannick Bertrand took a gate to the groin in a 2007 super-G race.
Competitive skiers fly down runs at incredible speeds, often exceeding 60 mph. Hitting something hard at that speed would definitely hurt, but hitting something hard with a particularly sensitive part of your body would be excruciating. So when Bertrand slammed right into a gate family-jewels-first, his high-pitched scream was unsurprising. What was surprising was the perfect commentary that immediately followed.
This is a clip you really just have to see and hear to fully appreciate:

It's unclear who the announcer is, even after multiple Google inquiries, which is unfortunate because that gentleman deserves a medal. The commentary gets better with each repeated viewing, with highlights like:
"The gate the groin for Yannick Bertrand, and you could hear it. And if you're a man, you could feel it."
"Oh, the Frenchman. Oh-ho, monsieurrrrrr."
"The boys took a beating on that one."
"That guy needs a hug."
"Those are the moments that change your life if you're a man, I tell you what."
"When you crash through a gate, when you do it at high rate of speed, it's gonna hurt and it's going to leave a mark in most cases. And in this particular case, not the area where you want to leave a mark."
Imagine watching a man take a hit to the privates at 60 mph and having to make impromptu commentary straddling the line between professionalism and acknowledging the universal reality of what just happened. There are certain things you can't say on network television that you might feel compelled to say. There's a visceral element to this scenario that could easily be taken too far in the commentary, and the inherent humor element could be seen as insensitive and offensive if not handled just right.
The announcer nailed it. 10/10. No notes.
The clip frequently resurfaces during the Winter Olympic Games, though the incident didn't happen during an Olympic event. Yannick Bertrand was competing at the FIS World Cup super-G race in Kvitfjell, Norway in 2007, when the unfortunate accident occurred. Bertrand had competed at the Turin Olympics the year before, however, coming in 24th in the downhill and super-G events.
As painful as the gate to the groin clearly as, Bertrand did not appear to suffer any damage that kept him from the sport. In fact, he continued competing in international downhill and super-G races until 2014.
According to a 2018 study, Alpine skiing is a notoriously dangerous sport with a reported injury rate of 36.7 per 100 World Cup athletes per season. Of course, it's the knees and not the coin purse that are the most common casualty of ski racing, which we saw clearly in U.S. skier Lindsey Vonn's harrowing experiences at the 2026 Olympics. Vonn was competing with a torn ACL and ended up being helicoptered off of the mountain after an ugly crash that did additional damage to her legs, requiring multiple surgeries (though what caused the crash was reportedly unrelated to her ACL tear). Still, she says she has no regrets.
As Bertrand's return to the slopes shows, the risk of injury doesn't stop those who live for the thrill of victory, even when the agony of defeat hits them right in the rocks.
