Re: the Dec. 4 guest column "Sabino High students debate banning plastic bags."

My household has been consistently using canvas bags for several decades. I hope the students in Mr. Johnson’s class also researched bio-based products. Many things we use that are made from petroleum are also made from things like corn and are biodegradable. I think studying this industry could be enlightening. This opportunity to learn about the politics of this industry and the demand for such products could be interesting also. I could see science fair projects comparing petroleum and bio-based products. Just a few thoughts.
