Microplastics ingested by marine worms are transferring toxic chemicals into their systems, having destructive consequences for ocean biodiversity, a new study has found.
A study published Dec. 2 in the journal Current Biology is the latest to warn of the ecological hazards of tiny grains of plastic known as microplastics, millions of tons of which pollute streams and oceans.
Microplastics are suspected to come from several sources. One is plastic beads used in facial scrubs or cosmetics. Microplastics also come from the breakdown of larger plastic materials, such as shopping bags, or the shedding of synthetic fibers from textiles by clothes washing.
The abundance and global distribution of microplastics in the oceans has steadily increased over the last few decades with rising plastic consumption worldwide. The study found that microplastics are threatening lugworms that comprise around 32 percent of the biomass along a shore.
When so-called "eco-engineer" lugworms consume microplastics, they absorb toxic chemicals that disrupt the worms' biological functions. It becomes difficult for the worms to eat organic matter such as silt, which in turn "changes the whole assemblage of animals that live around it," the study found.
"We are losing a large volume of plastic and we know it is going into the environment and the assumption being made by policymakers is that this material is nonhazardous, it has got the same ranking as scraps of food," Mark Browne, an ecologist from the U.S.-based National Center for Ecological Analysis and Synthesis, told the BBC.
Though microplastics are the most plentiful type of solid-waste pollution on earth, they are not considered hazardous under U.S. law.
Marine life other than lugworms also consume these microplastics, which absorbs chemical pollutants such as antimicrobials including triclosan and dyes. Pollutants from microplastics were found to accumulate at higher concentrations in the lugworms' intestines than pollutants from sand.
"For more than 40 years the bit that the scientists and policymakers didn't have was whether these particles of plastic can actually transfer chemicals into wildlife and damage the health of the organism and its ability to sustain biodiversity," Browne said. " That's what we really nailed with the study."

Gavin Newsom Sued for 'Completely Unacceptable' Approval of Oil and Gas Projects in California
By Brett Wilkins
Accusing California regulators of "reckless disregard" for public "health and safety," the environmental advocacy group Center for Biological Diversity on Wednesday sued the administration of Gov. Gavin Newsom for approving thousands of oil and gas drilling and fracking projects without the required environmental review.

From Greta Thunberg to Sir David Attenborough, the headline-grabbing climate change activists and environmentalists of today are predominantly white. But like many areas of society, those whose voices are heard most often are not necessarily representative of the whole.

<p>In 2004, Professor Maathai made history as the <a href="https://www.nobelpeaceprize.org/Prize-winners/Prizewinner-documentation/Wangari-Maathai" target="_blank" rel="noopener noreferrer">first African woman to be awarded the Nobel Peace Prize</a> for her dedication to sustainable development, democracy and peace. She started the <a href="http://www.greenbeltmovement.org/" target="_blank" rel="noopener noreferrer">Green Belt Movement</a>, a community-based tree planting initiative that aims to reduce poverty and encourage conservation, in 1977. More than 51 million trees have been planted helping build climate resilience and empower communities, especially women and girls.

<p>Known as the 'father of environmental justice,' Dr Bullard has <a href="https://www.unep.org/championsofearth/laureates/2020/robert-bullard" target="_blank">campaigned against harmful waste</a> being dumped in predominantly Black neighborhoods in the southern states of the U.S. since the 1970s. His first book, Dumping in Dixie, highlighted the link between systemic racism and environmental oppression, showing how the descendants of slaves were exposed to higher-than-average levels of pollutants. In 1994, his work led to the signing of the <a href="https://www.nrdc.org/experts/albert-huang/20th-anniversary-president-clintons-executive-order-12898-environmental-justice" target="_blank">Executive Order on Environmental Justice</a>, which the <a href="https://www.whitehouse.gov/briefing-room/presidential-actions/2021/01/27/executive-order-on-tackling-the-climate-crisis-at-home-and-abroad/" target="_blank">Biden administration is building on</a>.<br></p><span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="7983f54726debdd824f97f9ad3bdbb87"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/T_VjSGk8s18?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>

<p>Helping the clean-up operation after an oil spill in San Francisco Bay in January 1971 inspired Francis to <a href="https://planetwalk.org/about-john/" target="_blank" rel="noopener noreferrer">stop taking motorized transport</a>. Instead, for 22 years, he walked everywhere. He also took a vow of silence that lasted 17 years, so he could listen to others. He has walked the width of the U.S. and sailed and walked through South America, earning the nickname "Planetwalker," and raising awareness of how interconnected people are with the environment.</p><span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="09b968e0e9964e31406954dcea45981d"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/vgQjL23_FoU?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
