People see conservation as an exciting, romantic field to work in

But it's a tough life watching the places you love, study and fight for being destroyed

21.1°C in Chamonix today! 🔥🥵

A monthly record for February since at least 1880! 🌡️

Words truly fail to describe such early heatwaves, which are so out of season and detrimental to ecosystems.

‘Like doomsday’: why have salmon deserted Norway’s rivers – and will they ever return? North Atlantic populations are at a historic low, and this year 33 of the country’s rivers were closed during the fishing season as salmon farming and the climate crisis threaten the fish’s future

"Scientists have been warning of the rapidly declining North Atlantic salmon population (...) which in Norway has shrunk from more than a million in the early 1980s to about 500,000, a drop largely linked to the climate crisis."

Noticed in the #FlyFishing scene.

Las autonomías frenan la declaración de la anguila como especie en peligro Los gobiernos de las comunidades han reclamado realizar más seguimientos y tener más datos científicos antes de prohibir su pesca y consumo

Lamentable: hay info suficiente lo que falta es voluntad para afrontar problemas difíciles pero importantes. Por desgracia, los intereses económicos de unos pocos siempre pasan por los problemas ambientales de tod@s 🥲

Navigating Sweden's transition toward a low-carbon footprint for all To lower Sweden's individual footprint to less than 1 metric ton, transition policies need to consider variations across municipalities and those most at risk.

"We find individuals’ carbon footprints ranging from a whopping 17 tons per person to 3 tons annually across postcode areas. Income appears to be a key variable, with the wealthier producing the highest emissions."

It's lazy to divide territorial GHGs by population.

Què passarà al Delta si es declara l'anguila en perill d'extinció? El Ministeri proposa obrir la porta a restriccions més severes, però la Generalitat defensa mantenir la pesca d'aquesta espècie amb més control i reforç científic

La Generalitat (o part d'ella) en modo trumpisme
El DG de Pesca Sostenible es treu de la butaca això: "Si la població està malament és per moltes variables, i la que menys influeix és la pesca"
Les dades de la mateixa Generalitat refuten això
