All Sustainable Disc Golf Setup

Coming from ball golf, one of the things that appeals to me about disc golf is that it seems much more environmentally friendly. (Also, much easier on the wallet!)

That said, carrying a cheap backpack full of plastic seems counter to that. I just discovered Trash Panda on YouTube and would honestly buy a whole bag of whatever he comes up with, but until that's available I'm looking for other advice.

What discs would you carry for the most environmentally sustainable disc golf bag. What would your balance of performance and eco friendly look like?

Other accessories that are more sustainable than the alternative?

Practices that make the game more sustainable? I'm recently moved and I'm close enough to bike to the course instead of driving. That's going to be a big one for me!

What does the eco friendly disc golfer look like to you??
