for human survival, more focus should be on expanding into space

eventually mankind on earth will be extinct. who knows why, but it will happen. asteroid, our sun exploding, natural disasters, etc. before then, we need to have established colonies outside the solar system, and much further into the future, outside our galaxy.


Yes, space exploration has lead to many of the technologies of today but, at the moment, funding for outside-the-solar-system colonization is not feasible. Voyager 1 was launched in 1977 and took nearly 40 years to reach the edge of the solar system. The transport of humans and the millions of pounds of required life support equipment, food, and other supplies would likely take much longer. Keep in mind that every bit of food and water would have to be packed from the beginning.

Besides needing to pack every bit of supplies, with the exception of growing some plants, the effects of zero or lesser gravity on Earth organisms has proven to be troublesome. If the transportation to this outside-the-solar-system took the same amount of time or more there would be several effects on these zero gravity babies. They would have weaker muscles because of the lack of gravity to name two balance would be nonexistent when returning to a gravitational environment. Currently astronauts experience muscule loss in outer space even though they have developed methods to work out. Besides several physical issues with long term zero or low gravity environment exposure there are several mental issues as well.

The mental stress that would be involved with those who journey to the colonized location would have to be willing to leave absolutely everything they know behind. Along with that , isolation issues would be incredibly difficult to overcome. Knowing that you could never see anyone you know not selected for the trip to the colony would weigh heavily on day-to-day life possibly causing people to not focus entirely on the task at hand. With several personal mental issues to deal with social issues would be exacerbated by being in space.

If interpersonal issues arise, having people in close quarters to each other could be problematic. Even if people remain professional, it can be very difficult to overcome personality conflicts especially in close proximity all the time. Additionally, if someone is not performing their duties up to standards, there would be limited ways to counsel them or replace if need be.

With the state of modern space technology, the funding of the colonization of outer space, let alone other solar systems is impractical. The likelihood of catastrophic events is much higher when traveling through space and attempting to colonize an unknown location or planet. Yes there is possibility of an extinction event, but the danger of an asteroid, the sun exploding or natural disasters is a fraction of that of space colonization.

con has a point that it might be more efficient to travel later when better technology develops. but that doesn't mean we can't at least branch off onto mars or something, and perhaps venture into the next solar system. mental issues aren't that big of a deal, we can find ways to keep people busy, and if it's local, it's not like it's long term.


Even colonizing Mars would likely not be possible for many generations. The atmosphere is less protective than that of Earth's so the Sun's radiation would be a major problem. Also, Mars's atmosphere consists mostly of Carbon Dioxide up to 95% in some studies. It would be very difficult to over come the problems with the Mars atmosphere and take billions if not trillions of dollars to fund and maintain a colony on mars. Yes, a manned mission to mars will likely happen soon but that is a long way away from an actual colony.
As stated above, Voyager I took nearly 40 years to reach the edge of the solar system, not even to a location that we could inhabit. The issues of prolonged zero gravity environment exposure have still not been overcome and studies of rats born in space have shown the negative effects that go along with being born in zero gravity environments then returning to a higher gravitational environment.
The mental issues that would go along with leaving Earth to form a colony elsewhere in or out of the solar system are a big deal. They go beyond keeping busy. If you look at any refugee situation where people have to leave their homes, belongings, and often times loved ones there is incredible amounts of stress and hardship that come along with that. Yes people would make the choice to participate in the colonization, but that would not take away from the stress of leaving absolutely everything and everyone not participating in the colonization behind.
Debate Round No. 2


it may be troublesome but its entirely possible to colonize mars. we can branch off slowly while more technology develops that would be better used for branching further into space.


While in the future it may become more feasible to create a populated space on Mars the likelihood of a catastrophic event is just as likely to happen to Mars as it would be on Earth. Your original examples of possible extinction events include an asteroid, the sun exploding or other natural disasters would all also apply to Mars as well as outside of this solar system. The storms that occur on Mars are much worse than those that occur on Earth and would likely be catastrophic to any type of colony on Mars.

Not only would the same extinction possibilities apply to Mars and outside the solar system colonies, but the dangers, logistics, and funding involved with mass human travel in space are incredibly high and would not protect the human race from possible extinction events.

Until we have the technology to create a "warp drive" where we can physically bend space to where two points exist in the same space simultaneously, interstellar travel is likely impossible. The sheer amount of energy needed to even come close to light speed puts even the nearest solar system well out of range. We would also need to work out an artificial gravity design, because as con stated above the effects of long term zero gravity exposure can be very detrimental. That's why astronauts on the I.S.S. are only allowed to be up there for 18 months at a time, and have to exercise regularly, to keep their muscles from atrophying. I would love to see space exploration myself, but the limitations we have currently make this a feat that simply isn't possible. Even cryo freezing colonists on a sleeper ship probably wouldn't work, that technology too, is far from perfected at this stage.

This planet can sustain a thousand times its population.Why do you think we as a species will die out?

interesting debate in deed. I would love to see how pro responds to that argument.
