Can YOU Fix Climate Change? 📜Transcript

Can YOU Fix Climate Change? Never before in human history have we been richer, more advanced or powerful. And yet we feel overwhelmed in the face of rapid climate change. It seems simple on the surface. Greenhouse gases trap energy from the Sun and transfer it to our atmosphere. This leads to warmer winters, harsher summers. Dry places become drier and wet places wetter. Countless ecosystems will die while the rising oceans swallow coasts and the cities we build on them. So why don’t we just like… prevent all of that? Well, it’s complicated. @Kurzgesagt_InaNutshell

This Virus Shouldn't Exist (But it Does) 📜Transcript

This Virus Shouldn't Exist (But it Does) Hidden in the microverse all around you, there is a merciless war being fought by the true rulers of this planet, microorganisms.

Or so we thought. It turns out that there are giant viruses that blur the line between life and death – and other viruses hunting them. @Kurzgesagt_InaNutshell

How The Immune System ACTUALLY Works – IMMUNE 📜Transcript

How The Immune System ACTUALLY Works – IMMUNE The human immune system is the most complex biological system we know, after the human brain, and yet, most of us never learn how it works. Or what it is. Your immune System consists of hundreds of tiny and two large organs, it has its own transport network spread throughout your body. Every day it makes hundreds of billions of fresh cells. It is not some sort of abstract entity. Your immune system is YOU. Your biology protecting you from the billions of microorganisms that want to consume you and from your own perverted cells that turn into cancer. It's so manifold that it is impossible to cover in one video, so we’ll make a series looking at different aspects of it. Today, what happens when your body is invaded and your first lines of defenses are engaged in a fight for life and death? @Kurzgesagt_InaNutshell

How To Terraform Venus (Quickly) 📜Transcript

How To Terraform Venus (Quickly) Leaving earth to find new homes in space is an old dream of humanity and will sooner or later be necessary for our survival. The planet that gets the most attention is Mars, a small, toxic and energy poor planet that just about seems good enough for a colony of depressed humans huddled in underground cities. But what if we think bigger? What if we take Venus, one of the most hostile and deadly places in the solar system and turn it into a colony? Not by building lofty cloud cities, but by creating a proper second earth? It might be easier than you think. @Kurzgesagt_InaNutshell
