Countries Are Gathering In an Effort To Stop a Biodiversity Collapse (nytimes.com) 70

An anonymous reader quotes a report from The New York Times: As 20,000 government leaders, journalists, activists and celebrities from around the world prepare to descend on Glasgow for a crucial climate summit starting late this month, another high-level international environmental meeting got started this week. The problem it seeks to tackle: A rapid collapse of species and systems that collectively sustain life on earth. The stakes at the two meetings are equally high, many leading scientists say, but the biodiversity crisis has received far less attention. "If the global community continues to see it as a side event, and they continue thinking that climate change is now the thing to really listen to, by the time they wake up on biodiversity it might be too late," said Francis Ogwal, one of the leaders of the working group charged with shaping an agreement among nations. Because climate change and biodiversity loss are intertwined, with the potential for both win-win solutions and vicious cycles of destruction, they must be addressed together, scientists say. But their global summits are separate, and one overshadows the other.

This week, environment officials, diplomats and other observers from around the world gathered online, and a small group assembled in person in Kunming, China, for the meeting, the 15th United Nations biodiversity conference. The United States is the only country in the world besides the Vatican that is not a party to the underlying treaty, the Convention on Biological Diversity, a situation largely attributed to Republican opposition. American representatives participate on the sidelines of the talks, as do scientists and environmental advocates. Because of the pandemic, the conference has been broken into two parts. While this virtual portion was largely about drumming up political will, nations will meet again in China in the spring to ratify a series of targets aimed at tackling biodiversity loss. The aim will be to adopt a pact for nature akin to the Paris Agreement on climate change, said Elizabeth Maruma Mrema, the executive secretary of the convention.

Last year, officials reported that the world's nations largely failed to achieve the targets of the previous global agreement on biodiversity, made in 2010. If the new commitments are not translated into "effective policies and concrete actions," Ms. Mrema said this week at the meeting, "we risk repeating the failures of the last decade." The working draft includes 21 targets that act as a blueprint for reducing biodiversity loss. Many are concrete and measurable, others more abstract. None are easy. They include, in summary: Create a plan, across the entire land and waters of each country, to make the best decisions about where to conduct activities like farming and mining while also retaining intact areas; Ensure that wild species are hunted and fished sustainably and safely; Reduce agricultural runoff, pesticides and plastic pollution; Use ecosystems to limit climate change by storing planet-warming carbon in nature; Reduce subsidies and other financial programs that harm biodiversity by at least $500 billion per year, the estimated amount (PDF) that governments spend supporting fossil fuels and potentially damaging agricultural practices; and Safeguard at least 30 percent of the planet's land and oceans by 2030.

Acer Launches Bacteria-Resistant PCs (arstechnica.com) 69

During its next@Acer event today, the company announced three new PCs -- a laptop, a two-in-one, and a tablet -- that will be joining its antimicrobial lineup. Ars Technica reports: Something is considered antimicrobial if it's capable of "destroying or inhibiting the growth of microorganisms, and especially pathogenic microorganisms." That means it fights disease-causing things you can't see. Acer claims its Antimicrobial 360 Design, as it brands the feature, fights germs in two ways. First, high-touch surfaces -- such as the chassis's exterior and hinge, the keyboard, the touchpad, and the fingerprint reader -- are coated with a silver-ion agent. For years, research has pointed to silver ions' ability to fight bacteria. As a more recent report published in ACS Applied Bio Materials explains, "They can readily adsorb to most biomolecules (DNA, membrane protein, enzymes, or intracellular cofactors) in bacteria to inactivate their functions." Acer's silver-ion agent is compliant with regulations from the Environmental Protection Agency and the Biocidal Products Regulation; it can cut the bacteria count to 1,000 after a 99.9 percent reduction, based on the International Organization for Standardization 22196 test protocol. The 22196 standard specifies methods for testing the "antibacterial activity of antibacterial-treated plastics and other non-porous surfaces of products."

The products also use Corning Gorilla Glass coated with the silver-ion product. "This is done via trace amounts of silver ions leaching to the glass surface to eliminate the surface bacteria, while still offering other benefits such as improved durability and improved scratch resistance," Acer said. Acer introduced new antimicrobial PCs to its lineup in 2020 but is still adding to the roster. The company sees its antimicrobial coating expanding even further "across multiple product lines," an Acer spokesperson told Ars.
