I've been hearing a lot of talk about how bad plastic water bottles are for the environment. Is this true?

It depends on your definition of “environment”. If you mean the physical environment, then yes, plastic water bottles are bad for the environment because they’re made of plastic and can be harmful to wildlife if ingested or otherwise released into the environment. If you mean the social environment, then it’s hard to say whether they’re good or bad. People have different opinions about them.
