I guess you have to start somewhere, but I get what you are saying.
I love using straws. I have switched to paper straws at home though except for my tall cup which has washable thick plastic straws that came with tiny straw brushes to use to keep them clean. I was aghast seeing the videos on the humongous floating islands of plastics in the sea. When I see something crazy like that, I'm always wanting to say "I know we have to put trash somewhere, but who decided it was ok to dump in the ocean???" When the problem began, it should have been stopped and a better way figured out, either stop the manufacturing of the plastics or find another solution to discarding them. Ugh !
I haven't eaten with any wooden utensils yet. When I was working away from home though, I bought a set, knife, fork & spoon of real stainless utensils, but it was child size. Not infant mind you, but shorter than the regular adult size. I had them in a plastic container that I kept at work, so I didn't need to use a plastic fork or spork. I guess it might be a good idea to find something like that to keep in the car for future carry-outs. Wooden utensils.... Ugh!
I don't know the answer to all the things, but I know we can do better.
