is the world really going to end?

Off course the world is going to end. Everything has its beginning and has its end. But one thing i'm sure of is it's not going to end yet. It's not like we set a time and when that time comes it will really happen or when that time comes if we really dont want it to end yet we always have the option to extend it a little longer. In my understanding, they say God will end the world when the time is right. Who knows? We human beings in my opinion will do the ending of the world. and it has begun since we started polluting mother earth. Thus, we will be the one to blame when the end will come.
