I've only seen it increase. If you haven't seen the movie The Story of Plastic, I recommend it. Eventbrite lists free screenings all the time, which is how I saw it: https://www.eventbrite.com/d/online/story-of-plastic and eventually hosted my own screening. Here's the video of the panel discussion following the screening, featuring some important panelists: https://joshuaspodek.com/the-story-of-plastic-panel-video, all surprised by how much more plastic we create than they expect.

To your point, it also documents that we're increasing virgin plastic production, to say nothing of all other sorts of litter and waste.
