Sure, there handy but not everybody recycles them, they take so much energy to make and the chemicals leach into your water! Why not just ban the water bottle and get reusable ones that anr safe, you can use them and reuse them as many times as you want, and in the winter you can put hot drinks in them as well!  all they do now is land up in landfills waiting YEARS to disinagrate.
