100 yrs later, the world will be much more worse than now. If we don't change our mindset , this world will end early. If we start caring about our mother earth maybe we can still extend its life but we cannot escape the fact that this world will end soon and we are the one who to be blamed. We destroyed this world, we abused it, we only care about our self, our comfort and happiness that are so little. Not thinking about the future.
Nope... the world is not going to end anytime soon. But if the pollution levels increase any further, then the planet may become uninhabitable for the human beings. But then, the technology is advancing at a good pace. Who knows? In future the scientists may invent some method, through which the industrial pollution and global warming can be eliminated.
