In 2040 i will be in my mid-50s with children in their late teenage years. I hope they will see a world that is still worthy to live in and have dreams about. I hope the state of the world will be one where people understood that it is of utmost importance to look after our planet as well as each other - because otherwise the ground of our own existence will be destroyed. I hope that populism & nationalism will be overcome and people understand that we are all together in this. There is no space for divisive "me & you" and "us & them" - it's about finding a common ground. Compromises that work for everyone.
Do I think that this future is likely to happen? No. Do I hope it will? Yes, until the very end I will.
