EL GRAN ERROR de prohibir las bolsas de plástico:
Plastic bags generate fully 80 percent less solid waste than paper bags. They require 70 percent less energy to manufacture and 91 percent less energy to recycle. They occupy 85 percent less landfill space than bulky paper alternatives.
Now size up in-vogue reusable bags.
According to a lifecycle analysis by the United Kingdom’s environmental authority, shoppers would need to reuse their reusable totes 131 times before it became more environmentally advantageous than a plastic bag that was used just once. The Brits determined that it would take 7.5 years, assuming one trip to the market a week, for a reusable bag to have a lesser carbon footprint than a plastic bag used only three times.
But the problems with reusable bags aren’t simply limited to its gross environmental failings. They also pose a growing public health risk, as demonstrated by a particularly disturbing vignette from Oregon, where a girls soccer team was stricken by the Norovirus traced to a reusable tote.
In the seven years since San Francisco became the first American municipality to ban plastic bags in 2007, researchers have tracked a 5-percent increase in death from food-borne illness. That increase isn’t simply coincidental, but causal: According to a 2011 white paper by the International Association for Food Protection, a majority of reusable bags contain coliform bacteria.
