The end of the world

Before I say anything, I want you to know that I am christian and because of my faith I don't believe in the 'end of the world', but in the coming of God. And I think that if it really happens something like that, it is going to be the destruction of the world by the hands of the human being, but not the end of it.
How we all can see, every day, month and year, the world is more damaged because of us. The global warming has caused a large amount of natural disasters like fires and hurricanes. But there are some others that are not caused by the nature like: the melting of the Antartica, the radical change of the heat, the dryness, among others. All of these things has the human being in an alert period, because if we don't work to change this, it is going to get worse.
I don't think that there is an exact date that could tell us when it is going to be 'the end of the world', but there are possible approaches according to the ONU, which is in the 2050. Personally, I don't like to think about that, not because I want to deny the fact that we all have made a really big mistake by killing the 'mother earth', but because we have killed the earth and our lifes too with it.
I think that lots of humans will have to stay here and suffer the most extremes consequences, while others will experiment by leaving the earth to erradicate themselves in another planet.
Actually, recently there was an information that said that the scientifics has found another planet like the planet earth, where all the humans could live. So this shows us that the global warming situation it is real and it's not going to improve.
