Somethings I think I still need to know are what are the 3 Materials made out of? What takes up the most space in the environment? How long does it takes to make each mariteal? How much do each mariteal cost? and is it worth buying. I also need to know is Re-usable bags worse than paper or plastic. I think I need to know all of these things because we sh&l1dno#82u7;t use anything that harm the environment or takes up alot of space.I believe we should se things thats cheaper but still strong and takes up less space.
