We, as in all of humanity, will either die on this rock or we will not. Which one are you most comfortable with? I choose that we shall not over going extinct on some backwater planet in an uninteresting part of an average galaxy. There's no reason we can't solve the problems we have here on earth in tandem with exploring the stars. I believe it is called multitasking.
Our resources are finite. Many sources for the raw goods we need lay currently just out of reach in near space. Geologic statistics already show that some of our resources will only be available through recycling within 40 years because all viable sources on earth will be depleted. For some of these we have likely already waited too late. Establishing a human presence off world is becoming imperative.
Humans need to venture out into space because, at some point in our history, we will either run out of room or resources on earth. It would be foolish to think our resources will last forever. We need to find alternatives in case of such a scenario, where we could go to another planet or a space station.
A planet is the cradle of mind, but one cannot live in a cradle forever. Quoted by Konstantin Eduardovich Tsiolkovsky: the human species must take the next step sooner or later if we stay on earth as a whole we risk extinction like the way of the dinosaurs. Besides all those mineral resources on one asteroid in are Asteroid belt would have more than we could mine in 25 years!
If humans stay on earth without space colonization, we will eventually run out of space and resources. Therefore it is important that humans look to colonize space. This does not mean that we first travel to the nearest star as this is way to far and we do not posses the technology required to accomplish this. Therefore we start off small by starting on the moon with just a small capsule, this way it there is a problem then the colonists can receive help from earth. We then slowly keep adding capsules onto the original one thus creating a small colony. This will allow us to learn and discover the problems of colonizing another planet and again if the colonists have a problem the earth is not to far away. Then by using what we learn from the colonization of the moon we can apply that knowledge to colonizing mars. And then we look to other planets until we have the technology and knowledge to go to the nearest star. I understand why some people think that this is a bad idea and against our nature, but if the human race did not explore then we would not have colonized the entire planet and we would probably not be as smart as we are today. Thus colonization and exploration are necessary for humans to advance as finding problems and coming up with solutions is the best way to advance. There are also many benefits to colonizing space such as being able to mine resources, relieving pressure on earth by moving a substantial amount of people, and creating new jobs...
However not for the reasons as everyone says, I personally feel that as a species mankind needs to explore. We have this driving force, "as you will" that seems to be pulling us to explore. Some of our greatest minds where explores from Chistopher Columbius to Howard Hughes each where explores in there own way, and truthfully ask yourself this, "If I could would I truly stay here on Earth or given a chance would I not wish, no hope, to explore another world in all of its glory." My answer even with the risk of dying is, "yes.
We are expending Earth's resources. Earth has a carrying capacity. We will eventually be forced to move, or restrict amount of kids born, in order to survive as a human race and not die out. Businesses and big people with power are the only ones with the power to change our direction, but their power comes from doing exactly what's killing us. They're too concerned with the here-and-now.
Why wouldn't we colonize space? Eventually the Earth will be over-populated. There would be no need to worry about the pollution of the Earth if you make space factories. This means advancement in the medical field and technology. There is no reason why we shouldn't colonize space. The biggest factor is that we need money to do it.
"Colonization" of space sounds too imperialistic and much too reminiscent of a bygone era; it would be better to call this phenomenon "settlement" in space. Human settlement of space is the collective future of humanity if we can first get our act together. That would imply solving foremost (from a secular perspective) our environmental and social problems. Humanity as a whole still cannot get along with the environment nor with itself. If we can overcome these issues, then why not venture out into the great unknown?
Why not spread life as we know it to the far corners of existence? Did not God set all of creation before us to care for it? It is in our innate nature (without sin) to care for what God has given us. So yes, most definitely yes, humanity should settle in space, but in due time.
"Earth is the cradle of Humanity, but one cannot remain the the cradle forever."
Birds do it with their young, turtle do it, leave and wait for the eggs to hatch to explore the unknown ocean.
How are we any different?
Humanity was made to expand! We always do, our curiosity isn't going to kill us, it's what brought us here already!
Only issue is, that religion, and beliefs is what keeps us from doing what humanity does best.
We also have to lead humanity to a healthier road. Renewable resources and concentrate on medicine.
We have everything we need for space travel, except unity and finance.
If we overcome this, we can overcome anything as a whole.
Which will take decades, or even centuries if we must.
We'd do the same thing to the moon as we have to Earth. Besides it is supposed that the moon will leave us before the sun does, therefore wrecking our seasons and so on and so forth. We're all going to die then anyway so there's no real point in it. However, if you wanted to send criminals there with no life support then that's fine by me...
Logic dictates that there is no real chance of reaching the nearest star Proxima Centurai which is 4.2 light years away. The only propulsion systems that could achieve that kind of distance within a human lifetime are fantasy. This limits the debate to our solar system, which is demonstrably uninhabitable excluding Earth. Terraforming to livable levels on a planetary body (Mars) or moon level will not be realized before we make our own planet uninhabitable unless drastic lifestyle changes are embraced. Wake up people.
It would be like the whole New World thing again. The Native Americans almost got wiped out from the Europeans invading the Americas. Do we really want to do that? It is against our whole morale. We have been fighting so long for basic rights, do you think that we will respect rights of other life? It is a BIG universe people. Pretty sure that we aren't the only life out there. I ask you, is this worth it?
We shouldn't because we would deplete the Moon's resources just like we are depleting Earth's resources. Plus the foundation of the moon isn't stable enough to build on, the soil is too rich, and we would need to put massive oxygen tanks up there just to breathe. This would kill the economy with the costs of this this attempt.
Colonizing space would be extremely difficult if not impossible, and would be very costly. Even if we succeeded, we don't really need to colonize space, at least for a billion years. If humans are even around in a billion years, then would be a good time to colonize space. But not now.
we shouldnt we should find a way to stop using up our "renewable" resources quicker than they can replenish themselves. By people colonizing space its just trying to push our problem off on someone else. I hate to say it but the movie "wal-e" pretty much hits the nail on the head with what would happen. The physical toll on our bodies would be substantually greater then we could handle how do you get freshair in a space station? even if you could somehow create an atmoshphere it would not be the same as going for a run outside and if we lived in space people wouldnt feel the need to excercise if we live in space we would way less true but a number doesnt shange the sheer unhealthyness of the lifestyle.
There is really no reason to colonize space. We are terrestrial beings and we evolved for this planet, our bodies would start to shut down after long term space exposure. This planet has everything we need, and all we have to do to control the population problem is stop having so many kids! If we protect the earth there will be no reason to leave it. We belong on earth, and we should enjoy and protect this wonderful planet.
It's bad enough we've ruined plant Earth and continue to destroy the planet and our value system because of our greed and selfishness. Of what benefit could it possibly be to anyone to colonize space or other planets? We're sure to continue on our course of mayhem and destruction. The human race isn't equipped to care for anyone or anything with integrity or intelligence.
Many people could not handle the training standards, the way they must live, they will live there for there lives. What if fuel cannot be transported, what if something brakes down? Ordinary people would not be ready for this. Overall, the problem with colonizing space is that many ordinary people could not handle the large task.
WE as humans were born and made on this planet earth. What would you think if you had been shipped off millions of miles away from the home you were raised on. Also we as humans had already screwed up this planet why go to another and screw that one up as well. We should stay on our home planet
