Yes, you are correct that "a majority of the push for more environmentally safe products [is] a result of the market demand", but as we read in the parent article, environmentally safe products are not making a significant difference. This is a bit of an assumption, because the article only speaks of straws, and I'm extrapolating that to _all_ consumer goods. The article then goes on to highlight what _would_ make a significant difference: fishing net cleanup.

What I'm saying is that the significant mess made by commercial fishing should be cleaned up by commercial fishing - or prevented in the first place by regulating the practice.

If we look a little further down the line at consumer behaviour again, I will make the anecdotal assumption that the vast majority of consumers does not care in the least about the packaging of their products (or the number of plastic straw it comes with), as they are too busy budgeting their lives.
