Plastic Bag Purchases Drop 90% at Major England Retailers After Bag Fee Is Introduced
Charging grocery shoppers a small fee for plastic bags works.
At least that's what the UK government has found. Since it introduced a five-pence fee for plastic shopping bags in 2015, plastic bag sales at England's seven biggest retailers have fallen 90 percent, NPR reported.
"No one wants to see the devastating impact plastic waste is having on our precious wildlife," UK Environment Secretary Theresa Villiers said as her agency released the findings Wednesday. "Today's figures are a powerful demonstration that we are collectively calling time on being a throwaway society."

490 million fewer single-use #plastic bags were sold by major supermarkets last year. That’s less plastic harming our #environment.

The data comes from Asda, Marks and Spencer, Morrisons, Sainsbury's, The Co-operative Group, Tesco and Waitrose. Together, the seven stores sold about half as many bags during 2018 - 2019 as they did the year before, a drop from one billion to 549 million, according to BBC News. Across all major English stores, bag sales fell by 37 percent between this year and last, The Guardian reported.
English shoppers now use 10 bags a year on average, a far cry from the 140 bags they used in 2014, the year before the fee was introduced. The 2015 law required stores with 250 or more employees to charge customers the equivalent of around 6 U.S. cents per plastic bag, NPR explained. Smaller stores can opt in if they choose. Similar bag fees in Scotland, Northern Ireland and Wales apply to all stores regardless of size, BBC News said.
Maddy Haughton-Boakes of the Campaign to Protect Rural England celebrated the news, but said England could go further.
"The continued reduction in plastic bag use in our supermarkets is yet more evidence of the huge impact that a small financial incentive can have," Haughton-Boakes said, as The Guardian reported. "Theresa Villiers must now build on this success by rolling it out to all small shops. There is absolutely no reason the charge shouldn't be applied to all bags, paper as well as plastic, to bring an end to the use of these single-use items altogether."

Bag fees like the UK's tend to be better for the environment than outright bans, University of Sydney economist Rebecca Taylor told NPR earlier this year. That's because bans force people who reuse plastic grocery bags for trash to go out and buy heavier bags.
"What I found was that sales of garbage bags actually skyrocketed after plastic grocery bags were banned," Taylor said.
The bag fee is only one of several actions taken by the UK government in recent years to reduce plastic pollution. A ban on products using microbeads came into force in 2018 and another on single-use plastics like straws and stirrers was announced for England in May. It will go into force in 2020.
Approximately eight million metric tons of plastic enter the world's oceans each year, and the amount of ocean plastic will increase threefold in the next ten years if nothing is done, according to UK government scientists. Current levels of plastic pollution kill one million birds and more than 100,000 marine mammals annually.
Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
