I think many underestimate the influence consumers can have on the manufacturers. In some product categories, they have an option to choose a better alternative. If more did that, the manufacturers in other industries would see that there is a first mover advantage where they can grow their market share by reducing plastic usage. More R&D would be spent finding alternatives and the world as a whole would be improved.
But it all starts with us choosing alternatives whenever possible. If enough consumers do that, the other manufacturers will improve because it impacts their revenue.
