It’s no secret that uncurbed climate change and population growth are going to (and already have) put stress on the planet. But the situation is getting so bad that one prominent NASA scientist says we have to start thinking about terraforming Mars and that, in order for the human race to survive at current levels, we will eventually “need at least three planets.”
“The entire ecosystem is crashing,” Dennis Bushnell, chief scientist of NASA’s Langley Research Center said Thursday. “Essentially, there’s too many of us. We’ve been far too successful as the human animal. People allege we’re short 40-50 percent of a planet now. As the Asians and their billions come up to our living systems, we’re going to need three more planets.”
Bushnell was discussing the release of The Millennium Project’s “State of the Future,” an annual report that looks at global challenges and how they might be solved. He said that Mars is a good start, but we’d soon need even more space to live.
“If NASA terraforms Mars, that’ll take about 120 years, and that’s only one planet,” he said. “We’d need more shortly.”
It’s not the first time someone has floated the need for humans to colonize other planets, but usually such ideas are proposed as a way for the human race to survive in the event of a cataclysmic asteroid collision or nuclear war. In 2012, the World Wildlife Fund also suggested the three-planet idea, stating that we're using about 50 percent more resources than the Earth can support, and that by 2050 we’d need three planets to sustain that rate.
Bushnell didn’t say when he thought we might need three planets or what planets those might be—Mars is a good start, but beyond that, the Solar System is looking pretty barren as far as terraform-able planets go.
This is how seawater irrigation would work.
"The point isn’t to be alarmist or cynical, says Jerome Glenn, CEO of the Millennium Project. It’s about identifying the challenges Earth faces and finding a way to rise above them. “We have no right to be pessimistic. We have to find out what’s intelligent to do to make this species survive,” he told me. “If you think the problems aren’t going to get better, then why try. And if you think there aren’t problems, then why change anything?”
In any case, Bushnell wasn’t suggesting that we absolutely need to leave the Earth—he was saying that we need to stop consuming like we are. He’s got one solution in mind: Salt water farming.
Halophytes, a class of plant that grows well in salt water, could potentially be used to create biofuel by growing plants in the middle of the oceans (or at least using salt water to irrigate plants we do have in agriculturally-unproductive parts of the world). Scientists are working on the possibility, and an MIT project suggested that some pilot programs started in India, Pakistan, Laos, Algeria, and other poor countries should be started sometime this year, but so far, not much progress has been made. Bushnell says it’d solve most of our problems.
“If you grew halophytes on wastelands using seawater, in 10-15 years you’d have fuel that cost $50 a barrel. That’s half of what petroleum costs today,” he said. “With that, you could solve land, food, water, energy, and climate. All of that comes together.”
If we can’t do that, it just may be time to start buying land on Mars.
No Actual Science Allowed.
If I was forced to read the article, I would.
The two second title scan, which is easier, leads me to believe that:
The gays want Uranus?
> This has got it be a liberal dream, to start society over and construct a while new society based on liberal ideas.
Sooner or later someone with common sense will be born among them and upset their apple cart. The truth always prevails and they can’t stand it.
This is hogwash, which is not to say that the idea of human habitation of other planets/satellites isn’t really, really cool.
Oh. good gosh, the insanity. Ship off the liberals.
My husband and and I are in tears over that...ROFL
Living underground won’t be much fun.
“need at least three planets.”
They guy is in NASA, shouldn’t he be working on the rockets that will get us to the other two planets?
Besides the fact that radiation would kill them faster than a miserable life on earth living next to liberals...
Iow, Mars is suicide. Total garbage.
All this type of BS does is demonstrate their thinking.
What they’re not saying is the reality, which is that leaders need to collectively figure out how to “thin the herd”.
That should alarm everyone.
one of the FEMI ECO WACKOS said “we” “have lost our identity”.
she clearly has..and it wasnt recently....
I feel,....microaggressioned against just watching the video,...and no longer FEEL SAFE
Except of course, they will demand conservative money to do it.
he needs to stick to muslim outreach
Re: “They apparently forget the Population Zero efforts 4 or 5 decades ago.”
Very true. The left picked up the overpopulation ball and ran with it for decades. Suddenly, this black & white moron Obama comes along with an eye to repeal and replacement of white opposition to Democrats. Now the crazies on the left forgets all about overpopulation and feverishly embraces unlimited overpopulation of USA by third world illiterates, poverty-cases, criminals and terrorists.
No nation can survive half crazy and half sane.
LOL!
The RRAL reason is one planet can’t pay enough taxes to support the socialism Mother Earth and it’s bosses want.
It’ll take three.
ed. Now the crazies on the left forget all about overpopulation and feverishly embrace unlimited overpopulation of USA by third world illiterates, poverty-cases, criminals and terrorists.
It’ll be just like North Korea.
“The entire ecosystem is crashing,”
Where do they come up with this kind of garbage?
This is a NASA official?
Wow.
