My own predictions about the future.

Hello, this is my first entry on Itaki, and I am quite exited excited about it. I want to invite you to read my composition and comment the mistakes you have found while you were are reading. I would really appreciate your help!.

This is a futuristic theory from a sixteen-year-old teenager.
In the first place, I must make clear that i  I have got a quite pessimistic point of view about the future of our planet and civilization. I don't doubt that science will eventually, make possible for humanity to build robots and drones with artificial intelligence and superhuman powers which, will facilitate workpeople's jobs an  and start a new technology era, but, unhappily, it will raise unemployment rates in a shockingly  shocking manner.
Also, about the space travel, which is a highly a popular topic between within teenagers people these days, there are currently three companies working on making it possible: MarsOne, SpaceX, and, how not, NASA. Each of the three are is certain that they will be the first company to achieve that purpose. Even Michael Griffin, the administrator of the NASA said that one day, there would be more people living off the earth than on it. That theory implies other planets colonization, which seems quite like a very far-fetched point of view to me, but factible feasible nonetheless, considering the speed at which the technology is improving these days.
But, apart from those amazing scientific achievements, there's one thing that made me unsettled and scares me a bit when I think about it. What, if we get to it, will give civilization enough reason to abandon this planet and leave for the outer space?
And yes, I am talking about the destruction of our planet. In the first place, there's this increasing rate of the number of natural disasters in the past years, after several surveys, it has been discovered that this is due to the fact that the earth pols poles are shifting, destroying, along with it's  its constantmovement, our magnetosphere and tectonic plates. Also, the climate change, if not taken measures, will soon reach a point of no return, causing the flooding of coastal areas and rising of the food prices because of the reduction of planting areas. By last, the overpopulation will become a greater problem than it is now. It will grow to meet food supply and hunger along with pollution will grow along with it. Perhaps there will be a world war or an epidemic disease that will 'solve ' this problem, because it seems, that with our means, we can not do it on our own.

Thank you!
