I don't think that colonising Mars will happen soon. The colonisation of Mars mite not ever happen. We mite invent some way to travel between start systems in a faster than light manner before such time as it is practical to try and colonise Mars. Mars is far away it has large dust storms, it doesn't have enough gravity to hold some critical gases needed for our type atmoshphere in. Plus we already have one planet and im not so sure we are going to even manage to keep this one liveable with the ammount of polution we are pumping into the air. Global warming mite be able to stop up from reaching any of our dreams and soon.
As for the talk of "uncivilised" and "civilized" can you please define to us your own definition of these words so that we can understand if it is just a bad choice of words. I think calling the countrys uncivilized because they have strong believes that seem insain to not be the best wrods. I think that any country no matter how technologically advanced can end up with strong beliefs that are screwed up and not accept any thing different.
The real problem between people is missunderstanding and the fact that people dont take the time and effort required to try and understand each other. And the emotional reactions people have. People are just like monkeys with extra brain power. Still ruled by emotions and still using instincts to get through life. Look at how quickly half the arguments on here decended into personally attacking people for views that were not really personal. Look at Bettinas views they maybe wrong they may be right they maybe both as there is shades of grey. They world is not binary with yes or no anwsers all the time. Even if it may seem so. I think there will be alot of people out there with Bettinas opions and alot of people with Vladimirs opions. The thing that we should try and do is try and understand both sides and rationally understand both and you both mite end up compromising. I personally think the problem is related more with the fact that people in general like to label others and put them into groups and give one thing to single out thousands and some times millions of people of all being in a certain way. This may work in general, in a werid kind of way but these groups usually tend to dehumanise people to being a certain way.
I think the main problem with humanity and wars is that humanity as a whole is not understanding and resorts to violence all to often. Fight or Flight rather than talk and understand. That being said it takes bother sides to talk and understand and that doesn't usually happen with helps expand on my theory that the main problem is lack of understanding of different views.
