The two tobacco companies Altria and Philip Morris International combined made up 2% of the branded plastic litter found, both Danone and Nestlé each produced 3% of it, PepsiCo was responsible for 5% of the discarded packaging, and 11% of branded plastic waste could be traced to the Coca-Cola company.
I think you’ve hit it on the head with everyone in the chain being responsible- and I’ve never heard of the broken window theory but it makes alot of sense.
