if you haven't already, consider getting a reusable bottle not made of plastic, over time it degrades significantly and sheds a lot more microplastics in the water
Goodness, that needs to stop. I'll concede it's a life saving tool during natural disasters or in places where tap water is unavailable, but the rest of the time it's a symbol of waste and ignorance. On my walks I see at least one half full bottle of water every day on the ground. Some dummy paid real money for it, then couldn't be bothered to even dispose of it properly.
