Future of Human kind

   This trailer from the movie "Wall-e" , is a great example of the type of environment that we , every living thing on Earth, seem to be heading towards. Wall-e is robot that was left on Earth to clean the mess that our society did. Society destroyed Earth by throwing trash every where , destroying nature, polluting seas, polluting the air, and by living tones of space antenna on earth's gravitational field. In the movie "Wall-e" there is also another problem that society faces. After all the pollution , the government created huge ship to  leave Earth , in the ship there is city where society lives. After 700 years away from Earth , every person living in the ship is obese , thanks to technology every  human being are like that. No one has to walk anymore ,because there will be chair carrying them around , people are addicted to technology ,they  make the robots do every thing for them. And humanities only hope is to find plant that is capable on living on Earth. Which in the movie they do ,so when they get back on Earth they have other difficulty which is adapting on Earth again. They had to lean a  lot of things, such as farm , so they can eat vestibules and fruits , learn how to walk again, and learn the habits that humans use to had on Earth. This movie is such great vision of the near future , if society doesn't start taking care of Earth, our future generation will pay for the consequences.
    Some logical question that person would ask about would be. Is this even possible?Is it possible to have ship that is capable of fitting the whole world? Will be able to live on Earth again after all those thing? What will happen if we live on Earth will all the pollution? Is this the end for human race? What will happen with all the animals and plants? Will we be able to save the animals and plants? Is there still time to stop this? Can we use are knowledge to stop this? Can we use machines with out polluting Earth? Is there anyway we can make sure no one throws trash in environment? How long will it take to Earth to be in that condition? Will technology really make us obese? Is it even possible for whole society be obese? Will we be so addicted to technology that we wont even do anymore exercise? Will robots do everything for us? What will happen if we leave Earth and we wont back able to come back again? Are robots capable of clearing earth while we are gone?
