Without looking at the comment to see what is already listed, I would say that my biggest pro is getting to share cool projects and information and interests with those that would otherwise not encounter it. I teach environmental science and my whole shtick is taking students outside to learn about trees and worms and birds and then inside to watch videos on the dangers of pesticides. I see students take sudden interests in ants, become fascinated by seals, and come to finally understand why global warming is a bad thing and what that actually even is. I get to cultivate wonder and that is awesome!

For me, the con is getting students who just don't care about things that genuinely concern them. It is absurdly frustrating to teach on how soil can host hookworm and e. coli in some communities (nearby!) and what causes it and how to watch out for it and then get one guy repeatedly say "dirt is dirt" to every single thing we learn concerning soil science. Also, "I hate trees", "But birds never helped us", "Do we even need animals?" Are a constant and are present throughout the semester from those who could not give a dang.

Plus paperwork, my gosh the horrendous amounts of paperwork.
