Radical ideas do not change humanity.... only ethical ones do.

Although very revolutionary, Avaneesh, I really can't imagine how that idea would work in reality. You see, it's true that man would have no meaning at all if he didn't have hardships to overcome. However, we have enough errs in this world, even excluding that small, lingering threat of terrorism. Ridding the world of this wouldn't make our lives any easier. But letting it take a toll of millions of lives only reduces the population who would be willing to do anything constructive against other evils. Unless of course, you go back to your radical ideas.

As is my title, in reality, I do not believe radical ideas have the magnitude to change the ways of humanity, only ethical ones do. If you say, that the present day generation is responsible for all that is being done to the world, then the only real solution would be creating a better generation after us. And how is that possible, if our generation is the one to teach them?

You can participate in a million campaigns which aim at bringing down the birth rate, which would in its due course take years to complete. But in the same time, the death rate would also be dwindling and all our efforts would have gone to waste. The more radical solution to bring down the ills of over-population would be to gather all the people in the world below the poverty line, in a deserted region, and nuke them. In that way, you could say we're getting rid of over-population and poverty at the same time. Thats like two gigantic scratches erased from your Biology record. However, we live in a world where ethics overpower logical reasoning, and that does not allow us to do such a thing. So unless we resolve this attitude to an extent, such that we can put down emotional traumas for a greater need, our race is slowly degenerating by itself, which I believe is the true course nature intends us to take.
