I think we should fix Earth AND a portion should move to Mars. We should also create tech that allows inter planatery travel at a viable timeframe because the people in mars will get homesick eventually. Then we will have two planets and a model for how to create living environments in more. Then we can expand and become a multi planetary species. But Earth is our home and origin we should never just abandon it fully

I don't agree. I think a species with stupidity and genius and a varying degrees of perspectives and the rainbow of personalities of humans which have idiots that like to ban other people or even blow themselves and others up and one that discovers dark matter is just right for space colonization. A species that creates so many marvels for a better life but also creates horrors like the nuclear bomb that's a race that can thrive and move forward as opposed to a species of rational beings who always strive for peace prosperity knowledge and the betterment of life one that accepts all of its members and is all around angel-lile as realistically possible. But that might just be me

StarOcean said: Idk I agree with Tyson. Then again I love Tyson so maybe I'm bias. Always watch Star Talk                                      I just have to emphasize that Tyson does absolutelty not oppose colonizing Mars, he just isn't as pessimistic about humanity's future on earth as Hawking. Actually, he said that he can't wait for the current generation of kids and students to grow older and be in charge, because he thinks we will the things his own generation has ruined

I don't oppose it either. 

Anytime NASA does something new, something that has never been done before they need to make new technologies. All of these technologies benefit us on earth everyday. Colonising the moon would grow humanities impact on the universe, lessen our damage to earth and would give birth to completely new technologies that benefit all of us.

That's true but currently humans are not suitable to leave their planet as we still believe in self created ideas like religion.  It would be dangerous to spread such unproven ideas beyond the earth.  Let's wait a few thousand years until religion is considered mythology. 

First we achieve immortality. THEN we go ahead and start making Star Trek

sounds more like a sham to bring in a world government if you ask me

as someone has already mentioned... there's loads of uncolonised land on earth already... how exactly is it beneficial to ignore that and move to another more inhospitable planet and try to spend far more effort developing that?

people have been watching too much alien covenant

If we can't keep the world we actually evolved on, how the hell are we going to keep a home on a second rate planet that suits us less for reasons that many us don't even understand yet

You wont know what you're missing until it's gone

Stop shitting in your nest

Love walking in nature, go kayaking, surfing, mountain bike riding, camping in forests, watching wildlife? Then look after what we have, because it wont come back if you abuse it, nothing will be like our home world, everything else will be a poor copy at best, or a living hell at worst  

We must be that dumbest intelligent species this side of the milkyway 

As a whole we are smart tool makers, but we lack wisdom 

This. I totaly agree. We humans needs to learn to take care our planet for us and future generations instead we are trying to satisfy our desires by damaging it. At this rate, we will be in a danger zone in few decades as we are accelerating the damage by making ourself addicts to electronics.

We do not need to evacuate if we learned how to live.

Well unless you mean building cities in deserts, then there is only so much room to grow. Building on useful farmland is not a good idea. Cutting down green space is a bad idea for so many reasons, but acceptable to a certain degree for things such as creating more farmland.

Unless we're going to start making new landmass on a massive scale being reclaimed from the bottom of the oceans, with the newest dredger tech, then urban sprawl into rural area's can only go so far before it becomes a major problem. Many more skyscrapers would also help a lot with population growth, but would create another problem about convenience, transportation and congestion.

The "what if we get hit by an asteroid/meteor" question is relevant as well. Right now, we can only detect them out in space if they are a certain size. We are working on new tech that will allow the detection of smaller bodies, but this takes time. All it would take is a giant body breaking into smaller bodies, just small enough to go undetected, and have them pummel the Earth. We won't know they are coming, and even if we did, how would we stop all of them? 

Having another planet to call "home", or just be a place the species can continue on, just in case, is not a horrible idea. Not the greatest idea ever, but it has merit.
