Hi, I'm Mia, I'm 10 years old and I'm from Leipzig. Normally I'm jumping on the trampoline, reading comics, playing games or playing with Mika, my little arctic fox, or with my dwarf rabbits. But since last year, I've been hearing the word "climate change" everywhere, both at school and when my parents talk. There were even big demonstrations in Leipzig - and now I'm a bit curious and want to know more about it.
