Dear someone in the future,
Nobody knows what the future will hold for us, how much of everything will be left and which role we will play. I hope you did your part and you are proud of it.
Everyone should be aware that we have to change something. The topic of climate change should be addressed much more often in schools and at work, but also privately.
However, the most important thing remains to contribute to it actively. It does not hurt anyone to change their lives a little for the better and to enable future generations to live comfortably on this planet.
