I want to get into learning about environmental science, mainly physics and sustainability. I don't know where to begin or where to look to. Could anyone help?

Someone introduce to me an inexpensive hobby. Please also be my guiding light through it.

Any idea where I can get a second hand e reader from? Or even second hand tablets. Primarly for reading. I want to read on the go but carrying around books along with the stuff I already do carry is a little hectic.
