I guess you didnt read the entire thing?
"The study created a lot of controversial headlines for the claim that cotton tote needed to be used thousands of times to have the same impact on the environment as a single-use plastic bag.
If you look a bit closer, however, it doesn’t really spell the end for this eco-warrior favourite. The reason for these very large figures wasn’t water usage or CO2 emissions but instead damage to the ozone layer; damage that was caused by gases used to help transport the fossil fuels powering the pumps that water the cotton plants."
"I
t is an unfair generalisation, though, as not all cotton is produced in the way they describe. Any impact on the ozone layer could be easily mitigated by switching irrigation away from fossil fuels to more renewable sources. The Danish study reveals that if climate change alone is considered, the
minimum number of re-uses goes down to 149. That’s just two trips to the shop a week for one and a half years, a far more achievable number."

There something major missing from the Danish study as well, the disastrous impact of plastic bags on marine life. So uncontrollable is their spread that in 2019, an
American explorer breaking a world record for diving to the deepest part of our oceans, the Mariana Trench, found a plastic bag at a depth of nearly 11km. That means that plastic waste has made it to parts of our planet that humankind has even been to yet.
Although perhaps not as damaging to the environment in the way the Danish scientists measured, conventional plastic bags easily find their way into the sea where they can cause the death of marine animals. Several species of sea turtles are particularly fond of feasting on jellyfish and a floating plastic bag bears a striking and dangerous resemblance to their favourite food. A recent
Greenpeace study in French Guiana stated that an estimated 50% of all sea turtles have ingested pieces of plastic, something that makes them far more likely to wash up dead on our beaches."
