The Earth has survived some serious catastrophes. Here are the 4 worst.

Our planet's had a bit of a rough past. But the Earth is nothing if not a survivor.

Here are the four worst things the Earth has survived so far:

1. The Big Splash, aka that time the universe punched Earth in the face and may have created the moon

Imagine a young Earth. Like, super young. Only 20 million years after the solar system even formed. A little precious baby Earth.


And then imagine the universe smashing it in the face with an object the size of Mars.

That's the giant impact hypothesis, also known as The Big Splash. Scientists who back this hypothesis think that about 4.5 billion years ago, just after the Earth formed, another proto-planet called Theia may have slammed into it, ejecting rocks and magma out into space. Ouch.

It's not all bad, though. Some of that rock and magma may have coalesced out there in space and eventually turned in our moon. If this is true, it helps explain some of the weird things about our moon, like why Earth rocks and Moon rocks look so similar.

2. The Oxygen Catastrophe, aka that time Earth's entire atmosphere turned into poison and then turned the sky blue

After surviving The Big Splash, Earth had a nice little period of time where it got to relax and, you know, enjoy being covered in magma and stuff.

Eventually, however, a combination of gas emerging from inside the Earth and meteors crashing into Earth created oceans and an atmosphere around the planet. There were even some wiggly little bacteria-like things swimming around Earth's prehistoric oceans too.

But those oceans, skies, and wiggly things would have looked totally alien to us. That's because there was pretty much no oxygen in Earth's atmosphere (which would have made the sky orange and the ocean blood-red). That was just fine for primitive life-forms, though, because if you're a little anaerobic microbe, oxygen is super poisonous.


Before oxygen, most of the Earth's atmosphere would have been methane, which would have made its surface look a lot like Saturn's moon Titan. Image from ESA/NASA/JPL/University of Arizona/Wikimedia Commons.

Then, about 2.3 billion years ago, some little upstart cyanobacteria discovered photosynthesis and decided to start pooping out oxygen. After all, for them, oxygen is just waste, right?

For about 200 million years, cyanobacteria did just that. Most life on Earth kind of ignored it until suddenly oxygen was everywhere and nearly everything died. (Way to go, cyanobacteria.)

In fact, there was so much oxygen, it broke down the methane in the atmosphere and rusted the iron right out of the oceans, which turned the ocean and sky blue.

That wasn't so bad: Earth got some nice little green life-forms, and the ocean no longer looked like something out of "The Prince of Egypt." All was well. Right?

Hahaha, no. It gets worse.

3. Snowball Earth, aka that time Earth was more frozen than a Disney movie

It turns out the Earth was totally using the methane in the atmosphere to keep the planet from from freezing — so when the cyanobacteria from The Oxygen Catastrophe broke down the methane in the atmosphere, there was nothing more to say than ... welcome to Snowball Earth.

Scientists aren't sure whether this was a complete freeze or if there was a thin band of non-frozen water around the equator, but that's little consolation to the vast majority of the Earth, which was under ice sheets that could have been miles thick.

This probably hasn't happen just once, either. This kind of Earth-over deep freeze has happened again and again and again. The last bout of global freezing may have taken place about 650 million years ago.

But hey! Eventually Earth broke out of its little winter wonderland (possibly thanks to volcanoes), and life suddenly began flourishing like crazy!

In fact, for a while, things were going pretty well. Earth was starting to look like, you know, the Earth we know today. Too bad there was at least one more giant setback waiting in the wings.

4. The Great Dying, aka that time everything on Earth almost died

With The Big Splash, The Oxygen Catastrophe, and Snowball Earth solidly in the planet's rearview mirror, and a bunch of plants and animals running around on land, things were looking pretty good.

Then, about 250 million years ago, The Permian Extinction, a disaster so horrible scientists sometimes call it The Great Dying, happened. It more than earned its name, too. 96% of marine species went extinct as did 70% of land vertebrates.

What caused it? Scientists still aren't sure. Some think it might have been a collision with an immense asteroid or runaway methane or maybe what we now know as Russia simply ... exploding.

Either way, we know it took millions of years for life on Earth to recover. A lot of the more popular lineages of animals, like trilobites and a lot of mammal-like reptiles, were wiped out, leaving huge vacuums in the ecosystem. A few lineages did survive, however, including the ancestors of modern mammals and dinosaurs. Dinosaurs!

Thanks to climate change, today the Earth is going through some transformations too. With the planet's history as proof, chances are the Earth will survive climate change, too. Whether that includes humans, however...

Look, here's the thing. I like the skies the color they are now, thank you very much. I don't want to live through seas of lava, mile-thick glaciers over Acapulco, or the skies changing color (unless you're talking about a beautiful sunset or the northern lights, of course).

Fighting climate change isn't really about saving the planet. It's about saving ourselves and the other creatures that call Earth home. No matter how cool an ice planet with red skies sounds.

Should a man lose his home because the grass in his yard grew higher than 10 inches? The city of Dunedin, Florida seems to think so.

According to the Institute of Justice, which is representing Jim Ficken, he had a very good reason for not mowing his lawn – and tried to rectify the situation as best he could.

In 2014, Jim's mom became ill and he visited her often in South Carolina to help her out. When he was away, his grass grew too long and he was cited by a code office; he cut the grass and wasn't fined.

France has started forcing supermarkets to donate food instead of throwing it away.

But several years later, this one infraction would come back to haunt him after he left to take care of him's mom's affairs after she died. The arrangements he made to have his grass cut fell through (his friend who he asked to help him out passed away unexpectedly) and that set off a chain reaction that may result in him losing his home.

The 69-year-old retiree now faces a $29,833.50 fine plus interest. Watch the video to find out just what Jim is having to deal with.

The world officially loves Michelle Obama.

The former first lady has overtaken the number one spot in a poll of the world's most admired women. Conducted by online research firm YouGov, the study uses international polling tools to survey people in countries around the world about who they most admire.

In the men's category, Bill Gates took the top spot, followed by Barack Obama and Jackie Chan.

In the women's category, Michelle Obama came first, followed by Oprah Winfrey and Angelina Jolie. Obama pushed Jolie out of the number one spot she claimed last year.

Unsurprising, really, because what's not to love about Michelle Obama? She is smart, kind, funny, accomplished, a great dancer, a devoted wife and mother, and an all-around, genuinely good person.

She has remained dignified and strong in the face of rabid masses of so-called Americans who spent eight years and beyond insisting that she's a man disguised as a woman. She's endured non-stop racist memes and terrifying threats to her family. She has received far more than her fair share of cruelty, and always takes the high road. She's the one who coined, "When they go low, we go high," after all.

She came from humble beginnings and remains down to earth despite becoming a familiar face around the world. She's not much older than me, but I still want to be like Michelle Obama when I grow up.

Her memoir, Becoming, may end up being the best-selling memoir of all time, having already sold 10 million copies—a clear sign that people can't get enough Michelle, because there's no such thing as too much Michelle.

Don't like Michelle Obama? Don't care. Those of us who love her will fly our MO flags high and without apology, paying no mind to folks with cold, dead hearts who don't know a gem of a human being when they see one. There is nothing any hater can say or do to make us admire this undeniably admirable woman any less.

When it seems like the world has lost its mind—which is how it feels most days these days—I'm just going to keep coming back to this study as evidence that hope for humanity is not lost.

Here. Enjoy some real-life Michelle on Jimmy Kimmel. (GAH. WHY IS SHE SO CUTE AND AWESOME. I can't even handle it.)

What will future generations never believe that we tolerated in 2019?

Dolphin and orca captivity, for sure. They'll probably shake their heads at how people died because they couldn't afford healthcare. And, they'll be completely mystified at the amount of food some people waste while others go starving.

According to Biological Diversity, "An estimated 40 percent of the food produced in the United States is wasted every year, costing households, businesses and farms about $218 billion annually."

There are so many things wrong with this.

First of all it's a waste of money for the households who throw out good food. Second, it's a waste of all of the resources that went into growing the food, including the animals who gave their lives for the meal. Third, there's something very wrong with throwing out food when one in eight Americans struggle with hunger.

Supermarkets are just as guilty of this unnecessary waste as consumers. About 10% of all food waste are supermarket products thrown out before they've reached their expiration date.

Three years ago, France took big steps to combat food waste by making a law that bans grocery stores from throwing away edible food.According to the new ordinance, stores can be fined for up to $4,500 for each infraction.

Previously, the French threw out 7.1 million tons of food. Sixty-seven percent of which was tossed by consumers, 15% by restaurants, and 11% by grocery stores.

This has created a network of over 5,000 charities that accept the food from supermarkets and donate them to charity. The law also struck down agreements between supermarkets and manufacturers that prohibited the stores from donating food to charities.

"There was one food manufacturer that was not authorized to donate the sandwiches it made for a particular supermarket brand. But now, we get 30,000 sandwiches a month from them — sandwiches that used to be thrown away," Jacques Bailet, head of the French network of food banks known as Banques Alimentaires, told NPR.

It's expected that similar laws may spread through Europe, but people are a lot less confident at it happening in the United States. The USDA believes that the biggest barrier to such a program would be cost to the charities and or supermarkets.

"The logistics of getting safe, wholesome, edible food from anywhere to people that can use it is really difficult," the organization said according to Gizmodo. "If you're having to set up a really expensive system to recover marginal amounts of food, that's not good for anybody."

Plus, the idea may seem a little too "socialist" for the average American's appetite.

"The French version is quite socialist, but I would say in a great way because you're providing a way where they [supermarkets] have to do the beneficial things not only for the environment, but from an ethical standpoint of getting healthy food to those who need it and minimizing some of the harmful greenhouse gas emissions that come when food ends up in a landfill," Jonathan Bloom, the author of American Wasteland, told NPR.

However, just because something may be socialist doesn't mean it's wrong. The greater wrong is the insane waste of money, damage to the environment, and devastation caused by hunger that can easily be avoided.

The world is dark and full of terrors, but every once in a while it graces us with something to warm our icy-cold hearts. And that is what we have today, with a single dad who went viral on Twitter after his daughter posted the photos he sent her when trying to pick out and outfit for his date. You love to see it.




After seeing these heartwarming pics, people on Twitter started suggesting this adorable man date their moms. It was essentially a mom and date matchmaking frenzy.
