It is preferable not to use them at all, but if you really don’t have a choice, you can at least make sure that you recycle plastic bottles after use.
Why? Because if you don’t, one of two things will happen:
- That piece of plastic that you just threw away may get into the ocean and be swallowed by a poor marine animal, who thus will suffer a painful and unnecessary death.
- You may unwillingly swallow pieces of it, possibly coming from the same source mentioned above.
