Why should we leave Earth?

Question

I have to do a debate in science class, and my group is that we should colonize every planet & moon we can. So.. why should we leave Earth?

Answer 1

There are many reasons, but two main ones, in my eyes. One is that there is the ever-pressing need to explore, to know, to conquer. Humans have felt this need since we became sentient. We have an urge that tells us to move, to build up, then to move and build up again. Two is that we are totally messing up the Earth. Pollution is terrible, we're releasing too much Carbon-Dioxide into the atmosphere, and we're destroying our only way out. Sure, there's still a lot of medicine plants that we don't know about in the rain forests, but if we destroy that, how will we find them? Anyhow, I guess the watered done version is this:
We should try to leave our planet because it is dieing. WE are killing it. We should move on, and try again, learning from our mistakes.

Answer 2

Planet overpopulation. The earth is only so big and unlike humankind's early days where we could have ended up extinct from many different causes AND the fact that mortality rates are dropping and people are living longer, there will be less and less free space for people and all other life forms. We have been depleting the oceans of fish, depleting the land of vegetation and causing deadly gases to build. Also it just a matter of time before some fool does a stupid thing and the nuclear bombs start going off making whole areas of the planet unihabitable. The moon is drifting away from the planet which wreak major havoc and in addition, the sun will go super nova and will destroy the planet. (Wow how depressing, how bout saying we should leave earth for world peace??)

Answer 3

Why colonize space... How about this-as an insurance policy for the human race in case we blow ourselves up? Or get annihilated by a meteor strike?

Our grandchildren could, if they had the will, start to terraform Mars. With an initial investment (admittedly, trillions of dollars worth) of energy that would release the carbon dioxide and water sequestered in the regolith... Mars can be made much more habitable than it is now. Granted, it would take thousands of years to get a breathable atmosphere, but we could conceivably raise the average temperature above the freezing point of water and the pressure of the air to 1/2 to 3/4's of Earths. We still have to wear oxygen masks.... but THEN we would have an entire WORLD to colonize, and the human race's chances of extinction would drop dramatically.

Answer 4

Well, It may not happen in our life time but we are killing this planet at an ever increasing rate. The colonisation of other plants is still going to take some work. There are many road blocks preventing this. Serving the trip to even Mars still needs to be solved. Things such as bone density loss due to extend periods of weightlessness and bombardment from ultra violet light particles the penetrate not only the space vehicle walls but the travellers themselves.

Answer 5

What makes you think of this hasn't got here approximately until now? If there became an clever civilisation around and latest with the dinosaurs, how might all of us comprehend? there became a piece of writing interior the Mail the day previous exhibiting a "computing device" from 150bc which became used for astronomy. The Mayan calander has super awareness equipped into it and maps exist, that are copies of copies etc and centuries previous which tutor Antarctica without ice. the place did those very progressed artifacts originate. If we knew our civilisation became probably to be wiped out sometime by potential of say an asteroid, does not we build a base on say the Moon or Mars and seal it below the exterior. the backside might in basic terms incorporate advice asserting- We existed and it is what we provide you! we would additionally artwork on advancements in area shuttle particularly than conflict and its achieveable shall we be good adequate to create colonies, a number of which might prevail others of which might die out. i'm not a alien deliver nut yet I surely have examine broadly and there are some issues which in basic terms component to a sophisticated civilisation having existed interior the previous which "disappeared". The info is there for people who choose for to look.

Answer 6

I think eventually the earth is going to become inhabitable for human beings. Pollution, climate changes and in a few million of years scientists say the earth is going to be too close too the sun to maintain any kind of life on the planet.

Answer 7

Because we will learn from our mistakes on Earth and build an new colony on another planet thus more chances of living once the world start to die.

Answer 8

There is so much to see and learn in outer space.
Look at all the good things that have come from space exploration: the use of fiberoptics, which are such a great assist in modern medicine, for example.

Answer 9

Some people say that earth will be uninhabitable because of global warming in the near future, and if not that then the sun exploding in however many billion years its gonna be. But realistically, we have lots of time. thats not to say, however, that we shouldn't develop our technology to do so when need be

Answer 10

In a few hundred billion years the sun will go out. But it wont go out in till it burns all its fuel, so when it needs more fuel it will swallow the planets closest to it. Most likely the inner planets. Which includes Earth. So if you want your family in the future to die a terrible death, vote to stay on earth!
