   You say cans must be lined. Humans do not need plastic in   
   their diet. No cans do not need to have plastic. You need   
   to adjust to world with less plastic, humans adapt, survive.   
   Our garbage is too much. Expect less convenience, less shelf life,   
   and less pollution by the chemistry industry.
