How are plastic water bottles bad for the environment?
Plastic water bottles or other pressurized plastic bottles are really bad because they are constructed of two layers of plastic with overlapping grains which makes them stronger and more resilient than other plastics of the same thickness. One layer withstands damage from one direction while relying on the other layer to keep it from tearing. They tend to degrade very slowly because of this strength. The best thing to do with any recyclable is to reuse it. Reuse is exponentially better than recycling because it requires no energy other than what “you” put into it. There is no reason you can not reuse a water bottle as long as you practice minimal sanitation.
