"Discarded shells from restaurants and hotels are being used to restore damaged oyster ecosystems, promote biodiversity and lower pollution in the city’s bays...

Nestled in between the South China Sea and the Pearl River Delta, Hong Kong has been seen historically as an oyster hotspot. “They have been supporting our livelihood since ancient times,” says Anniqa Law Chung-kiu, a project manager at the Nature Conservancy (TNC) in Hong Kong. “Both oysters and their shells are treasures to humans.”

Over the past five decades, however, the city’s sprawling urban development, water pollution, as well as the over-harvesting and frequent seafloor dredging by the lime industry – which uses the crushed shells to make construction material – have destroyed Hong Kong’s oyster habitats and made the waters less hospitable for biodiversity.

The more oyster colonies falter, the worse the problem gets: oysters are filter feeders and purify water by gobbling up impurities. Just one Hong Kong oyster can filter up to 200 litres of water a day, more than any other known oyster species. But decades of rapid industrialisation have largely halted their water-purifying services.

The depletion of Hong Kong’s natural oyster reefs also affects the ability of local farmers to sustainably cultivate their oysters in a healthy environment, denting the reputation of the city’s 700-year oyster farming tradition, designated by Unesco as an “intangible cultural heritage”.

Inhabitants of the coast feel abandoned, says Ken Cheng Wai-kwan, the community leader of Ha Pak Nai on Hong Kong’s Deep Bay, facing the commercial city of Shenzhen in China. “This place is forgotten,” Cheng says. “Oysters have been rooted here for over 400 years. I ask the question: do we want to lose it, or not?”

A group of activists and scientists are taking up the challenge by collecting discarded oyster shells and recycling them to rebuild some of the reefs that have been destroyed and forgotten in the hope the oysters may make a comeback. They’ve selected locations around the island where data they’ve collected suggests ecosystems still have the potential to be rebooted, and there are still enough oyster larvae to recolonise and repopulate reefs. Ideally, this will have a positive effect on local biodiversity as a whole, and farming communities.

Farmers from Ha Pak Nai were among the first to hand over their discarded shells to the TNC team for recycling. Law’s team works with eight oyster farmers from Deep Bay to recycle up to 10 tonnes of shells every year [over 22,000 pounds]. They collect an average of 870kg every week [over 1,900 pounds] from 12 hotels, supermarkets, clubhouses and seafood restaurants in the city, including some of its most fashionable establishments. About 80 tonnes of shells [over 176,000 pounds] have been recycled since the project began in 2020.

Restaurants will soon be further incentivised to recycle the shells when Hong Kong introduces a new fee for waste removal – something that is routine in many countries, but only became law in Hong Kong in July and remains controversial...

Preliminary data shows some of the restored reefs have started to increase the levels of biodiversity, but more research is needed to determine to what extent they are contributing to the filtering of the water, says Law.

Scientists from the City University of Hong Kong are also looking to use oyster shells to increase biodiversity on the city’s concrete seawalls. They hope to provide tiny, wet shelter spots around the seawall in which organisms can find refuge during low tide.

“It’s a form of soft engineering, like a nature-based solution,” says Charlene Lai, a research assistant on the team."

The company behind the Coastal GasLink gas pipeline project in northern B.C. has received a whopping $346,000-fine from the B.C. government for environmental deficiencies and providing false and misleading information.

According to the Ministry of Environment, Coastal GasLink Pipeline Ltd. failed to meet conditions of its environmental assessment certificate. In a Thursday statement, it said compliance officers found inadequate erosion and sediment control during several inspections along the pipeline route in April and May last year.

The company also gave false and misleading information last October as well in relation to maintenance inspection records, the province found. That cost Coastal GasLink $6,000, while the erosion control matter cost $340,000.

“As a result of continued concerns, the Environmental Assessment Office has prioritized the CGL project for compliance monitoring, with nearly 100 inspections by air and ground since the project started in 2019,” B.C.’s statement reads.

“These inspections have led to the EAO issuing 59 warnings, 30 orders – including 13 stop-work orders – and more than $800,000 in fines.” [...]

Here's the link to the report from the Union of Concerned Scientists described in this story from EcoWatch:

A new report from the Union of Concerned Scientists (UCS) has found that Tyson Foods dumped hundreds of millions of pounds of pollutants into U.S. waterways from 2018 to 2022. The pollutants came from company facilities including slaughterhouses and processing plants.

UCS analyzed publicly available data from the U.S. Environmental Protection Agency (EPA) and found that Tyson Foods processing plants released 371.72 million pounds of pollutants into waterways from 2018 to 2022. Half of the pollutants were dumped in waterways of Nebraska, Illinois and Missouri. The group published the findings in a report titled Waste Deep: How Tyson Foods Pollutes US Waterways and Which States Bear the Brunt.

“As the nation’s largest meat and poultry producer, Tyson Foods plays a huge role in our food and agriculture system and has for decades exploited policies that allow big agribusiness corporations to pollute with impunity,” Omanjana Goswami, co-author of the report and an interdisciplinary scientist with the Food and Environment Program at UCS, said in a press release. “In 2022, the latest year for which we have data, Tyson plants processed millions of cattle and pigs and billions of chickens, and discharged over 18.5 billion gallons of wastewater, enough to fill more than 37,000 Olympic swimming pools.”

Waterways in Nebraska had the most wastewater pollutants dumped by Tyson Foods plants, about 30% of the total or 111 million pounds, UCS reported. The pollutants dumped in Nebraska included 4.06 million pounds of nitrate, which a 2021 study linked to increased risks of central nervous system cancers in children.

According to the National Provisioner, Tyson Foods is one of the top meat and poultry processing companies in the U.S. From 2018 to 2022, it generated 87 billion gallons of wastewater, based on EPA data. This wastewater can include pathogens and microorganisms (such as E. coli) and slaughterhouse byproducts, such as body parts of animals, feces and blood.

As noted in the report, the dumped pollutants contained high amounts of nitrogen (34.25 million pounds) and phosphorus (5.06 million pounds), which can contribute to algal blooms in waterways. As UCS pointed out in its analysis, many Tyson Foods facilities are located near waterways that are home to threatened and endangered species. 

The facilities are also positioned near historically underserved communities, leading to additional pollution near and burden on vulnerable populations.

“Pollution from these plants also raises environmental justice concerns,” Stacy Woods, co-author of the report and research director for the Food and Environment Program at UCS, said in a press release. “We know from previous research that almost 75% of water-polluting meat and poultry processing facilities are located within one mile of communities that already shoulder heavy economic, health or environmental burdens. In mapping these plants, we found Tyson largely fit that pattern, with many plants located near communities where people live with more pollution, less socioeconomic and political power, and worse health compared to other areas of the United States.”

The report provides insight into a larger problem. As The Guardian reported, meat processing pollution in the U.S. is much higher and goes beyond Tyson Foods.

“There are over 5,000 meat and poultry processing plants in the United States, but only a fraction are required to report pollution and abide by limits,” Goswami told The Guardian. “As one of the largest processors in the game, with a near-monopoly in some states, Tyson is in a unique position to treat even hefty fines and penalties for polluting as simply the cost of doing business. This has to change.”

The Tories caused this pollution crisis by privatising our water utilities.

Shareholders make £millions while we have no clean rivers, lakes and beaches.

Hi, our observatory is currently under threat of a sand mine being built 500 ft away from it. I'm going to a city council meeting tomorrow and it'd be very cool to have a petition with Numbers associated to point at saying "don't fucking do this", so if you wouldn't mind signing/sharing, I'd appreciate it!

There are a couple of glaring problems with the proposal that I'll list under the read more if you're interested:

Telescopes have mirrors. Sand + mirrors = Bad, since it will cover them and possibly cause scratches (on the mirrors that we've just replaced which cost millions of dollars and years to do)

Sand in the air will scatter light, which makes images blurry when taken by the telescope

It might also get in gears and such, ruining hardware

This observatory has been around for 60 years and is used for citizen/student outreach, including K-12

The mine would be threatening gopher tortoise environment when they are already endangered

The water coalition is also against this due to the possibility of pollution of the Suwannee river

Air quality will drop, making it dangerous for telescope faculty (including myself because I have asthma) and residents

The sand mine is trying to get an exception to be built in a residential zone. You know, where people live?

Noise pollution will bother residents and vibrations could affect instrumentation

Light pollution in one of the few remaining dark skies of Florida will negatively affect observing and residents

"Despite a huge amount of political opposition from the chemical industry, the US Environmental Protection Agency (EPA) announced its first regulations aimed at limiting quantities of PFAs, or ‘forever chemicals,’ in American drinking water.

For decades, Polyfluoroalkyl substances or PFAs have been used for coatings that resist fire, oil, stains, and water and are now found in a wide variety of products like waterproof clothing, stain-resistant furniture, food packaging, adhesives, firefighting spray foams, and non-stick cooking surfaces.

There are thousands of PFAS compounds with varying effects and toxicity levels, and the new EPA regulations will require water utilities to test for 6 different classes of them.

The new standards will reduce PFAS exposure—and thereby decrease the health risk—for 100 million people in the U.S.

A fund worth $1 billion for treatment and testing will be made available to water utilities nationwide—part of a $9 billion investment made possible by the 2021 Bipartisan Infrastructure Law to assist communities impacted by PFAS contamination.

“Drinking water contaminated with PFAS has plagued communities across this country for too long,” said EPA Administrator Michael S. Regan in a statement Wednesday.

Under Regan’s leadership, the EPA began in 2021 to establish a roadmap for dealing with widespread PFAS contamination, and so far they’ve gathered much data, including monitoring drinking water, and begun requiring more reports from businesses about use of the unregulated substances.

The agency reported that current peer-reviewed scientific studies have shown that exposure to certain levels of PFAS may lead to a myriad of health issues that are difficult to specify because of the variety of compounds coming from different places.

Regardless, the 66,000 water utility operators will have five years to test for the PFAS pollution and install necessary technology to treat the contamination, which the EPA estimates that 6%–10% of facilities will need. [Note: Deeply curious where they got a number that low, but anyway.]

Records show that some of the manufacturers knew these chemicals posed health hazards. A few major lawsuits in recent years have been settled that sought to hold chemical companies, like 3M, accountable for the environment damage.""

The cost of removing a contaminant toxic to fish after decades of coal mining in British Columbia's Elk Valley is more than three times what the company has set aside for the work, says an independent consultant's report.

Gordon Johnson of Burgess Environmental says in the report that it will cost $6.4 billion to reverse rising selenium concentrations in Canadian and U.S. waters and operate those treatment systems for 60 years. That amount does not include costs for land reclamation.

Teck Resources said it will set aside a total of $1.9 billion for the cleanup. [...]
