I don't think that it did. And I don't care about what the humanity is consuming, as long as it doesn't pollute the world excessively.
Your rights end where my rights begin, etc.
It's laws. It's society. It's government. It's mobilization by citizens to get the government to regulate waste disposal -- to make improper disposal of waste illegal, and to fund the creation of easily-accessible environmentally-friendly waste disposal mechanisms.
Consuming soft drinks does not pollute the environment. Throwing bottles into rivers does. Your disdain for soft drinks has you mistaking these for the same thing.
I'm not against soft drinks, again. I'm against plastic pollution, be it from plastic bottles or from textiles or packaging materials or whatever.
Producing plastic causes plastic pollution, no matter how it's disposed of.
