Lots of information on these two pages of PDF that shows that you have no idea about what you are talking about.
Let's look at some of these "arsefacts" you posted critically, shall we?
When we are talking about a product that is widely used, it will have huge aggregate quantities. Such large numbers are good for propaganda, which is what this pamphlet by Suffolk County, NY government basically is.
"It requires 2.2 billion pounds of fossil fuel and 3.9 billion gallons of fresh water to produce the 100 billion plastic bags the US consumes each year."
Billions and billions. Tsts. But if we divide, it allegedly takes just about 10 g of fossil fuels and 150 mL of water to make a plastic bag. That looks far less impressive. Especially since it just says "plastic bags" which implies all plastic bags, not just the very thin standard shopping bags that do not use much material compared to other plastic bags people might use.
"The manufacturing of plastic bags produces a billion pounds of solid waste and 2.7 million tons of carbon dioxide (CO2)per year."
4.5 g of solid waste and 27 g of CO
2 in other words.
"Plastic shopping bags are made from polyethylene, a thermoplastic made from oil. Accordingly, reducing the use of plastic bags will decrease our dependence on fossil fuels. "
Not by much.
And it goes on like that.
I reuse my grocery shopping bags. They are useful for carrying small things and as trash bags, e.g. in a car or to line small trash bags like you might have in the bathroom.
And you have to compare these plastic bags with alternatives. How much energy and other inputs are required to make paper bags?
As far as reusable bags, how many trips do they last in practice? How much energy and water is needed to clean them?
And compare the plastic shopping bags with all the plastic packaging that ends up inside the bags. There is easily far more plastic inside the bags than in bags themselves.
