One thing I wish didn't exist is light pollution. So many stars we never see because of city lights. I learned that from my telescope hobby. It gets frustrating trying to find a pitch black place, or having to use filters to see things.

I do think we take for granted often the beautiful nature all around us. I think a lot of people in big cities with all the concrete and steel buildings can get depressed being out of nature. When you are away from all that pollution and buildings the beauty is all around you.

That's great advice to make a point to appreciate beauty, we can get so lost in work or school and we forget how amazing all this is. Makes me want to travel around the World, I hope one day I'll be able to do that. I need to find my old pictures I took in a trip to Peru, it was amazing, right at the ocean.

(Edit: oh I see your a psychonaut, me too :) I might get into some of those stories one day. You should to, I think people would find those stories interesting )
