It's reduce, reuse, recycle, in that order. You are arguing that we have no problem, and we don't need to do any of the three! No wonder it's an unpopular opinion. Reducing consumption means reducing production. It doesn't matter how effective litter prevention and recycling programs are, it doesn't matter how seemingly bullet-proof landfills are, some percentage of produced plastic ends up as waste in the environment (estimates range from 5 to 11%). Production goes up, litter goes up. Simple equation.

We need to massively reduce single-use plastics.

Even in advanced landfill-having countries, single-use plastics end up as litter in the environment, but the millions of tons per year. I've personally picked up 500 bags of garbage on 4 different continents. Landfills or not, it's everywhere.

We need to massively reduce single-use plastics.
