Terraforming Mars vs. Terraforming Earth | Neil deGrasse Tyson

#neildegrassetyson #terraformingmars #earth on StarTalk Neil deGrasse Tyson discusses whether we should focus on terraforming Mars or on Terraforming Earth.

My first reaction was "We won't have corporate interests polluting faster than we can clean it up." Then I realized those corporations will be the first ones there.

Great video, Tyson dropping some good knowledge.👍

My thoughts exactly. Mars, as it currently stands, lacks the necessary conditions to support life as we know it. The prospect of terraforming Mars remains a highly speculative endeavor. Even if such a transformation were possible, there is no assurance that the resulting environment would be self-sustaining.

The potential risks associated with dispatching humans to a terraformed Mars are considerable. Our understanding of Earth’s atmospheric dynamics, particularly at the microscopic level, is still in its infancy. Transposing this limited knowledge to an entirely different planetary context could have unforeseen and potentially hazardous consequences.

Furthermore, the financial implications of a manned mission to Mars are staggering. The costs associated with spacecraft development, astronaut training, mission execution, and subsequent colonization efforts would be astronomical.

Given these considerations, the notion of colonizing Mars may seem more akin to a pipe dream than a feasible objective for our near-term space exploration efforts.

Bro this is what I been saying for years

Finally!!! Someone who wants Earth to get better, not Mars!! Our planet is so beautiful, let's take care about it!!

Far easier to fix Earth than go to any other planet.

Terriforming requires us heating the planet which were already doing using green house gasses specifically carbon 12 for plant life to then help the oxygen production and with the perfect ballance builds a perfect atmosphere and circumstances for life the beginning process would not be vary nice to live through I would imagine but I don't much feel free to clue me in

Rational thinking with good common sense is the sharpest knife there is for cutting through B.S. Thank you, Dr. Tyson for telling it like it is.

Back in the 50s and 60s we were interested in picking up litter and planting trees. Not so much today. 😢

[rahmuss]

I love it. The only problem is that in earth too many people are fighting against reversing the damage. Or at least don't care enough to try.

[pretty]

Let’s terraform our own damn beautiful planet 🌎

[brianleegraf]

Hi mister Tyson speaks truth and science

[JessicaLopezffxiv]

But on mars, you get to start over with new leadership

[gideonwilliams]

The Paris Accords were about suggesting a way to sequester enough carbon to neutralize our output. The US and China said no

[chillpillology]

lol the only problem is we will not be able to terraform anything within a time frame before our own extinction

[vinvink]

The goal isn't to ditch earth, it's to make humans a multi-planetary specie. Adding to the livable real estate.

[GBCxPrime]

Ay big fan of your shorts. I think the whooshes are a lil loud on this one. Thanks for all the great stuff!!

[lastchild]

We have terrraformed Earth. And screwed a lot of it up. Our choices were mostly destructive, not all, but when we terraformed dry places, we did so at the expense of the more fertile.

Now the Qs are; Ho how do we do more of it to regain atmospheric safeguards, and benefit all life. And balance out the skewed distribution of fertile lands.???

[merion]

There are geopolitical obstacles to this. Unfortunately, it is quite possible that these geopolitical conditions will disappear with the collapse of human society, which is why we need a colony on Mars, from which our descendants can possibly re-terraform the Earth.

If we attempt to terraform Mars, and it goes bad... a couple people die. If we attempt to do it on earth and mess up... I'd rather test it on Mars.
