The 4 greatest threats to the survival of humanity

Dig into the 4 biggest existential risks that threaten the survival of humanity, and explore how we can safeguard our future.

Since then, our risk of either extinction or the collapse of civilization has steadily increased. Just how likely are we to destroy ourselves? And what poses the greatest threat to our survival?

"If it isn't perfectly aligned with human values." I think humanity is not perfectly aligned with human values, no wonder AI is having a hard time getting there.

Yes ted ed, give me a global existential crisis, because apparently my own life existential crisis ain't enough

[sapphyrus]

Focusing on the greatest problems is a great way to take your mind off one’s own lesser problems. Thanks, Ted-Ed!

[dangerfly]

It's terrifying to know that we gleefully elect leaders that are supremely self-interested and have little regard for the future of humanity.

[alaskawashington]

the fact that all the bystanders were clapping in each scenario gave me horrified shivers down my spine. the accuracy is unreal.

[IsaiahHollins]

Fearing the thought of extinction is a great excuse to take a sick day off work 👍

[lwkey]

I'd say that one of Humanity's greatest threat is Humanity itself

[Hallands.]

1) Human greed
2) Human control-sickness
3) Human selfishness
4) Human cowardice

mom, ted ed gave me existential crisis again!

The diversity of the concepts that this channel has is simply amazing. Always one of my Fav channels. But the thing that makes me sad is you are not continuing History on trail series like the other concepts are done. Please make sure about that.

My god, this video is truly deep and the plot twist at the end is just genius.

[angrygoose]

Real question though: Why is this lady presenting humanity’s greatest weaknesses to a ship full of aliens?
_There is a traitor in our midst._

[ilertargenthorne]

The animation is crisply simple as always!

Great job to the animation team at Ted-ed

"But the complete destruction of humanity has never happened before"
I learn something new every day!

[yoavhayun]

Loved that bit where the dinosaur ate the human, really makes you look like you know what you're talking about

[zoenavales]

"Because most of the risk is from human action, and it's within human control."

We future of humanity lies in our hands. We can destroy it if we want to, but we can also save it. The choice is ours.

[ruipedroleite]

Not trying to be picky, but, TED-Ed videos have a very important educational & informative purpose. Having a T-Rex eating a human @ 1:20 is a bit misleading, especially for children that might not get the joke. Dinosaurs & humans never coexisted, EXCLUDING CHICKENS.

[manuraghuram]

0:46 - 0:54 those words are enough to sent chills down our spines

[sonalgupta]

WOW! Just wow
Ted ed knows how to leave us both scared and amused at the same time
Its absolutely true that it highly depends on our choices
It reminds me so much about various episodes of Doraemon about extinction of humans and take over by AI 😭

Wonderful video. My grandfather worked for the Amour Research Foundation on a feasibility study to determine whether the United States could detonate a nuclear bomb on the surface of the moon. I believe he also studied the effect of radiation fallout on the ionsphere, so I can appreicate the topic.
