In my personal opinion, future life of our World will be brighter than today's and I really hope the changes we young people see, could become true within a short amount of time, because everyone need to live in a better World.
My biggest concern, firstly regards the climate change: in the "world of my dreams" people have learned how to live without polluting and have a better relationship with nature, with both plants and animals;
Secondly the health topic: for me it's important that everyone of us have a free healthcare, physical and psychological in order to achieve the best version of ourselves.
Last but not least, the government situation: I really am hopeful that in 2040 (or even before that date) government and citizens would reach a common point to start going on the same path: the one that leads to the best planet we've ever seen and had.
