How about a reusable water bottle made from recycled materials? This will not only be a practical gift that he can use every day, but it will also align with his passion for sustainability. Additionally, you could consider getting him a reusable tote bag for groceries or a set of reusable silicone food storage bags. For a more experiential gift, you could also look into eco-tours or workshops focused on sustainable living practices.
Or you can get him a star map with the date when he was born.
