Gas Utilities Knock Electric Appliances

As cities phase out the installation of gas lines in new buildings to cut down on methane emissions, gas utilities have been staging adversarial campaigns nationwide. In Santa Barbara, California, residents received warnings that a gas ban would dramatically increase their bills. The Pacific Northwest group Partnership for Energy Progress, funded in part by Washington state’s largest natural gas utility, Puget Sound Energy, has spent kelly-sikkema/Unsplash.com at least $1 million opposing heating electrification in Bellingham and Seattle, including $91,000 on bus ads with the slogan, “Reliable. Affordable. Natural Gas. Here for You.” In Oklahoma, Arizona, Louisiana and Tennessee, the industry has worked aggressively with state legislatures to pass laws to prevent cities from passing cleaner building codes. The American Gas Association even has a website (aga.org) dedicated to promoting cooking with gas. Surveys have found that most people are open to switching water heaters and furnaces from gas to electric versions, so gas company advertising has made gas stoves a symbol of wealth, good taste and status for consumers, builders and realtors. Gas connections in American houses are at an all-time high, but as Americans realize that natural gas is a powerful contributor to climate change and source of air pollution, at least 42 cities have strengthened building codes to discourage expanding gas hookups in new construction. callum hill/AdobeStock.com

Artificial Intelligence Joins Fight Against Marine Litter

MARLIT, an open-access aliaksandr marko/AdobeStock.com web app based on a deep-learning artificial intelligence algorithm, will promote the detection and measurement of floating plastics in the sea with a reliability of over 80 percent, according to a study published in the journal Environmental Pollution conducted by experts at the Biodiversity Research Institute of the University of Barcelona.

Floating macro-litter is a threat to the conservation of marine ecosystems worldwide. The largest density of floating litter is in the great ocean gyres (systems of circular currents that spin and catch litter), but polluting waste is also abundant in coastal waters and semi-closed seas such as the Mediterranean. The analysis, using artificial intelligence techniques and more than 3,800 aerial images of the Mediterranean coast along Catalonia, will permit researchers to detect the presence, density and distribution of plastic pollutants in seas and oceans worldwide. Historically, direct observation by boats and planes formed the basis for assessing the impact of floating marine macro-litter, but the massive area of the oceans and the amount of data required have made it hard in the past for researchers to progress with new monitoring studies.

Composting Human Remains is a Reality

Frustrated with the limited options for environmentally friendly burial services and the rampant use of embalming in most funeral homes, which turns these sites into major groundwater polluters, environmental activist Katrina Spade founded Recompose (Recompose.life), the country’s first human composting funeral home, in Seattle. Formaldehyde, one photo courtesy of recompose.life of the most common embalming chemicals, is a carcinogen.

Inspired by Spade’s idea, Governor Jay Inslee passed a bill legalizing composting as a form of human burial in 2019. Before then, the only legal and eco-friendly burial options were natural burial sites, of which there are only one or two hundred in the country. Both cremations and traditional burials cause environmental damage. Recompose offers an innovative funeral service that turns human remains into healthy soil. It gives Washington state and surrounding residents a chance to make a positive environmental change through their death, as well as their life. The process is said to save a metric ton of CO2 in the burial process, and the facility is accepting clients throughout the Northwest.
