We noticed this on our grocery stop when in Cancun. They will happily sell you a cotton type bag. Rather thick. They certainly have a bigger carbon and water footprint, but won't clog up the lagoon or ocean like plastic, at least not long term.
With cotton not derived from fossil fuel, the carbon footprint for a fabric bag could easily be smaller than plastic. Further, since fabric bags are reused many times instead of being single use, over the lifetime of the bag, a reusable (and reused) cotton bag will come out ahead. Even a reusable plastic bag (or plastic coated fabric bag) will come out ahead.
The water footprint to produce fabric is not inherently larger than for plastics. And in any case, water can be treated and reused, regardless of whether product is fabric or plastic.
