Economically viable is a term which exists on a sliding scale. As we progress and age the scale is shifted to where things which aren't economically viable today may become economically viable in the future.

As of today we have no need to gather resources from the Moon; but 100 years from now that might be different.

One square km of lunar dirt, a couple of meters deep, contains more easily extracted aluminum and titanium than is produced in a year on Earth.

That is not economically viable. A lunar mission costs billions of USD and even those space shuttles can carry no more than 1 tonne of lunar material back to the earth. Who is willing to pay $10 billion for a tonne of Aluminium?

Just another incentive to begin harvesting extra-terrestrial resources... Our Solar System has plenty to go around...

There isn't really a finite amount of resources but rather a finite amount of energy... New resources can be created given enough energy and the right technology to fuse/fizz atoms effectively...

The question isn't whether we will run out of resources on our planet. The question is whether we'll have adequate resources to sustain ourselves until an alternate source of materials can be found and exploited...

Of course, blame capitalism, despite the fact that we don't actually live in a capitalist society right now you also can't ignore the fact that we're rapidly running out of resources to build things and sustain ourselves, this is about survival, not ideology.

More like a corptocracy based on crony capitalism. The capitalist mindset is a big reason as to why we are running out of resources.

No we're not, we're running out of resources because there is always a finite amount of resources, stop ignoring mathematics.

This is true but you can't ignore the fact that the capitalist mindset creates incentive to harvest resources at an unsustainable rate.

I completely agree. Grin

That seems unlikely. I think that there has been so much time since the beginning of the universe that allows for life similar to what exists here to appear, that encountering species at close to our technological level is very, very unlikely. I mean, there could be species literally billions of years old around, and chances are they would have little to no interest in contacting us, which might explain why there seems to be no evidence for alien life - no need to assume everyone has taken the route humanity is taking.

I doubt that; since the universe had a beginning, and since all matter has had the same rules placed on it since that beginning, the speed at which planet Earth formed into an ideal place for life to begin is going to be about the same speed as any other planet, meaning those planets, perfect for life as is ours, had creatures evolving at about the same rate and in similar ways considering they've experienced a similar environment as ours, meaning they're roughly in the same spot that we are now: intelligent beings, sentient or otherwise, duking it out for resources, with little time to focus on developing the technology and gathering the resources necessary to travel at lightspeed for decades, if not centuries (not to mention being able to live that long, or to reproduce in-between), just to see more of the same.

The universe is only about 13 billion years old, with our planet having circled the sun about 4 and a half billion years ago (that means about 8-9 billion years are spent just trying to bring order to the chaos.)  Within those 4 1/2 billion years, only the last billion has been spent with multi-cellular life forms, and only the last 200k years spent with your modern day man.  Unless this sentient lifeform managed to find a way to evolve several magnitudes faster than the species of our planet, or those planets formed way faster than all the others, it's safe to say that, while we're not alone, there's little room to precede us in technological advancement, and even if there was, the universe is a huge place and if you have the technology to travel around like that, there's probably something much more interesting locally to that lifeform.  Needless to say, there's no society that can be billions of years old, and no aliens are aware we exist aside from a mutual understanding that the odds of them being the only sentient species in the universe are zilch.

The theory that the universe had no beginning is actually taking root.

Everything has to have a beginning.


You sure? Why is that? I don't think either of us can say such things with confidence.

next mass extinction will be caused by:

food & beverages
cigarets
extreme poverty
pollution
WW3

no natural causes. this one is manmade and slowly aims at taper the "unsustainable" global demographic growth.

PS: + japanese people doomed because of fukushima's radioactivity (besides economical and social collapses there too).




My bet is on WW3. Seeing lots of geopolitical conflict all over the world and internal political unrest.

The humanity has advanced so much there is literally NO possibility of human extinction.
Humans will be the last species to extinct.

Nope, we are part of the ecosystem actually. Species that re predatory are the first to go extinct.


Therefore if 99% of life goes extinct, we humans are going to be higher on the least than at least 50% of life.

Without certain organisms we cannot plant our crops or feed our farm animals.


Certainly some humans will survive perhaps 0.1% or so. But you couldn't exactly compare life in an inhospitable world to life on the planet today.

Right now, species are going extinct at an extreme rate, all the time. Species we haven't even discovered yet are going extinct.

All the potential benefits of medications created by such species wiped away in the blink of an eye.

According to a recent study (http://www.sciencemag.org/content/345/6195/401) scientists warn we are approaching the next mass extinction.
What are your thoughts on this topic, and how do you think that will affect us.
The most interesting part for me, is that the other 4 mass extinctions were probably caused by natural events such as super-volcano eruptions or asteroids strikes, but this next is will be our fault... We are as destructive as a super-volcano eruption lol that can't be good :/

I can see the fall of the US empire but it will take 100years and it will stay powerful

UK lose the empire in less than 2 generations and from the wealthiest nation to IMF bailed out in less than 3 generations.

Well it seems to me that humans consider themselves the undisputed king of apex predators. I don't think that is the case.
There is a very important characteristic of apex predators that doesn't apply to humans. Apex predators don't need to have natural enemies because they've evolved in such a way that they're able to keep their numbers in check on their own. The human population on the other hand is clearly out of control, we keep proliferating and we cannot stop. I don't think humans are apex predators. This in turn would suggest that we do have a natural enemy after all, maybe one we are not necessarily aware of.
When our nemesis finally surfaces, it'll be time for mass extinction  Grin Grin

You're missing the potential that an M class planet may have formed around another star perhaps a billion years earlier than our Earth and if that planet developed life it would be a billion years ahead of our planet.

Our planet after all is made from heavy elements that came from the death of other stars and perhaps previous planets that may have held life.  We could all be recycled from ancient civilization that failed to escape their sun's death.

Yes!

http://en.wikipedia.org/wiki/Kardashev_scale

The Kardashev scale is a method of measuring a civilization's level of technological advancement, based on the amount of energy a civilization is able to utilize. The scale has three designated categories called Type I, II, and III. A Type I civilization uses all available resources impinging on its home planet, Type II harnesses all the energy of its star, and Type III of its galaxy. The scale is only hypothetical, but it puts energy consumption in a cosmic perspective. It was first proposed in 1964 by the Soviet astronomer Nikolai Kardashev. Various extensions of the scale have been proposed since, from a wider range of power levels (types 0, IV and V) to the use of metrics other than pure power.

In fact it would the the 6th extinction, I remember they speaking about that in the X-files when they revealed the alien plans to destroy the human race.


And if the nature did nothing to protect 99% of all living species that ever existed, why should we bother too much about them? Species die and are born everyday, its the nature.
