I have a keen interest in everything related to the environment and try to do my best:

  • plant-based diet
  • zero waste:
  • local cleanup events

I read a lot of nonfiction books, mostly about science (astronomy, environment, climate change, …), philosophy and personal development. Besides that, I swim, try to play the guitar and learn how to draw (pencil)
