Is overpopulation real? Is Earth filling up with too many humans? How many people can Earth hold, anyway? As our species approaches 8 billion, human overpopulation is a major concern for many people. How can we reduce poverty and our impact on the environment? Do we need a forced one-child policy or something? Maybe not, because when we look at the science and history, populations seem to control themselves. This week we look at all these questions and more.

Special thanks to John Green! And to Amber Faasen and the Dallas Zoo herpetarium team!

During the 2017 Project For Awesome livestream, I promised I’d make a tuatara video if we hit our fundraising goal, and I’m a man of my word! Little did I know I’d get to meet a tuatara and learn things about a 200 million year old branch of life that would blow my mind. Get ready to meet the chillest reptile, weird living fossil, and star of Turtles All The Way Down… the tuatara.

The Most Extreme Life Forms On Earth… And Beyond?

Life, uh… finds a way
Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub
↓↓↓ More info and sources below ↓↓↓

What have we learned from exploring Earth’s harshest locations? That pretty everywhere we look for life, we find it. From smoking hot hydrothermal vents to icy deserts, up in clouds and inside rocks, extremophiles have found a way to survive. These survivors and adapters are not only teaching us about life on Earth, but expanding the possibilities of where life can exist elsewhere.

Why Is Blue So Rare In Nature?

Duh, except for the sky… and the ocean…
Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub
↓↓↓ More info and sources below ↓↓↓

Among living things, the color blue is oddly rare. Blue rocks, blue sky, blue water, sure. But blue animals? They are few and far between. And the ones that do make blue? They make it in some very strange and special ways compared to other colors. In this video, we’ll look at some very cool butterflies to help us learn how living things make blue, and why this beautiful hue is so rare in nature.

How Atom Bombs Can Uncover Forged Art ☢️😱

↓↓↓ More info and sources below ↓↓↓

It’s been estimated that 1 in 10 works of fine art are forged or misattributed. The truth is, no one really knows how much fake art is out there, because many art counterfeiters are so skilled that their paintings are almost indistinguishable from the real works. But even counterfeiters can’t beat physics! From atomic bomb remnants to ancient atoms, here’s some of the amazing ways that science can detect fake art.
