In this bracing talk, coral reef ecologist Jeremy Jackson lays out the shocking state of the ocean today: overfished, overheated, polluted, with indicators that things will get much worse. Astonishing photos and stats make the case.

It may not appear very lively six feet underground, but a single teaspoon of soil contains more organisms than there are human beings on the planet. From bacteria and algae to fungi and protozoa, soils are home to one quarter of Earth's...

What do beavers, termites, and prairie dogs have in common? They all change their environments! Last time we talked about how humans change their environments, but humans are animals and all animals change their environments just by...

When Stephen Sillett was a boy, he took to the forests of Pennsylvania with his brother and grandmother. Looking up into the dense branches and leaves, his curiosity was piqued: What was hidden up there? Wendell Oshiro tells the story of...

Though we probably won’t find a literal Atlantis beneath the sea, that doesn’t mean that a human settlement hasn’t ever been lost to the water. Meet Doggerland.

How do you define "nature?" If we define it as that which is untouched by humans, then we won't have any left, says environmental writer emma Marris. She urges us to consider a new definition of nature -- one that includes not only...

A unique ecosystem of plants, birds and monkeys thrives in the treetops of the rainforest. Nalini Nadkarni explores these canopy worlds -- and shares her findings with the world below, through dance, art and bold partnerships.

It sure seems like some plants really don't want you hiking through their woods, but maybe your immune system is just overreacting.

By piecing together a complex ecological puzzle, biologist Willie Smits believes he has found a way to re-grow clearcut rainforest in Borneo, saving local orangutans — and creating a thrilling blueprint for restoring fragile ecosystems....

Extreme weather sometimes happens in very specific areas thanks to extreme surface temperature differences.

SciShow welcomes back Diana Six to talk to us about current news on the Mountain Pine Beetle Outbreak. Then, Jessi Knudsen Castañeda stops by and brings a familiar friend whose anatomy may help scientists develop better hypodermic...

Today's wildfires burn, on average, twice the amount of land they did in 1970. The reason? We've been working too hard to put them out. Want to learn more about the topic in this week's video? Here's a keyword/phrase to get your googling...

Savage-Rumbaugh's work with bonobo apes, which can understand spoken language and learn tasks by watching, forces the audience to rethink how much of what a species can do is determined by biology -- and how much by cultural exposure.

Paul Andersen describes the process of ecological succession. During this process life reestablished itself after a disturbance. During primary success all of the material is removed including the soil. For example during a volcanic...

When asked to build housing for 100 families in Chile ten years ago, Alejandro Aravena looked to an unusual inspiration: the wisdom of favelas and slums. Rather than building a large building with small units, he built flexible...
