Atlantic Salmon return to England, free buses transform French city, tiger family spotted in China, polystyrene ban expands in New York, and researchers make hydrogen from wastewater
Here’s your weekly roundup of environmental good news stories from around the world. Enjoy the first post of 2026!
Atlantic Salmon return to English rivers
Young Atlantic salmon, which are critically endangered in Britain, have been spotted in three English rivers for the first time since 2015. Their numbers plummeted because of climate change, pollution, invasive species, and dams. These latest sightings are a hopeful sign that efforts to clean up waterways, improve water quality, and restore habitats are paying off. Conservationists say the return of salmon, which are highly sensitive to pollution, signals broader ecological recovery across these river systems.
Free buses transform a French city
In the French city of Dunkirk, free public buses have reshaped daily life. Mayor Patrice Vergriete, who has a doctorate in urban planning, pledged during his election to make buses free. The city underwent the transition from 2014 to 2018, and today there are 150 free buses running seven days a week across 18 routes. Since the program was implemented, ridership surged, car use declined, and residents reported improved access to jobs, education, and social life. The policy has helped reduce congestion and emissions while supporting low-income households. It serves as an excellent model for New York City, where Mayor Mamdani is looking to do the same.
Rare Amur tigress spotted with five cubs
Camera traps in northeast China have captured the first-ever footage of an Amur tigress caring for five cubs — an extraordinary and encouraging sight for one of the world’s most endangered big cats. The rare observation suggests improving habitat conditions and successful conservation measures in the region, offering renewed hope for the long-term survival of the species.
New York expands polystyrene foam ban
New York State has expanded its ban on polystyrene foam to include containers used for cold storage, closing a major loophole in earlier regulations. The move aims to reduce plastic pollution, protect waterways, and limit exposure to harmful chemicals, while encouraging businesses to shift toward reusable or compostable alternatives.
Scientists make hydrogen from dirty water
Researchers have developed a method to produce clean hydrogen fuel using wastewater, turning an environmental liability into a valuable energy resource. The process avoids the need for purified water and could lower costs and emissions associated with hydrogen production. If scaled up, the technology could support cleaner energy systems while helping address water pollution.
