By 2040 the planet will be different from what it is today , technology will evolve to the point that humans do not serve to work . The heavy work will be done by Robots. On the other hand I think that pollution will decrease because also an evolution in fuels replacing these with electricity . People will stop using real money to use virtual money, they will stop carrying documents to use a chip that will replace and make them virtual . On the one hand, it's good, but on the other hand, not ,, because we are moving towards a future without freedom.
