Huh? The graph shows that you need to use an organic cotton reusable bag 20,000 times in order for it to have the same environmental impact as a single use LDPE bag.
Oh wow ok, I misread the chart. That's not great at all. I do stand by the content my original comment as a general principal. But this does indicate that there is not enough awareness around the environmental impact of various materials, assuming their analysis takes everything into account.
