Take the quote from the parent comment:
> Most Americans’ daily routines depend on single-use items and throwaway plastic packaging,
What purpose does singling out Americans here serve?
1. It makes readers of The Guardian feel superior?
2. The paper wants to attract more American readers who want to feel they are concerned and environmentally conscious?
It's pushing a sense of 'holier than thou' with a readership who live in countries and cultures whose economic systems make widespread use of single-use plastic on a very large scale. It's a sanctimonious attitude that's great for consumers of these articles but never the driver of real change.
