So elend, was sich dort gerade abspielt. Es ist zum Heulen.

Eine blonde Frau (Julinae Diller) blickt in die Kamera. Dazu das Zitat: "Die Versuchung, mit dem Goldabbau Geld zu machen, ist sehr mächtig. Ein Hektar Land kostete bis vor wenigen Jahren umgerechnet zwischen 600 und 800 Euro. Heute zahlen die Goldgräber dafür 10.000 Euro oder mehr. So mancher wird da schwach."

Als Teenager überlebte sie als Einzige einen Flugzeugabsturz im peruanischen #Regenwald. Heute kämpft Juliane Diller gegen illegale Goldgräber – um das Lebenswerk ihrer Eltern zu retten. ‪

Mitigating the NIMBY effect on renewable energy: Experimental evidence from survey-based interventions in Catalonia The deployment of solar and wind power plants is widely supported in principle, yet local communities often resist when such projects appear in their …

"Our findings confirm the presence of a NIMBY effect on renewables, with landscape considerations emerging as a key factor. However, targeted communication about climate benefits and local financial gains, as well as implementing smaller-scale projects, significantly reduces resistance."

This year marks the 100th birthday of #bioacoustics, established by Ivan Regen in 1925, which studies how animals hear, produce and propagate sound.

Let’s discover this discipline with @nicolasmathevon.bsky.social, Professor of Saint Etienne University, in the first episode of Acoustic World.

🚨 Excited to share our new research! 🚨

We tackle a big question in conservation: how can we make smarter use of existing surveys to learn about places and species we haven’t yet been able to survey? 🏔️

New research carried out in Colombia by the University of Cambridge suggests that local surveys assessing the effect of land clearances on biodiversity may be underestimating the impact by as much as 60%.

Vögel vergiftet: Freispruch für 87-jährigen Jäger Am Landesgericht St. Pölten ist am Montag ein 87-jähriger Jäger vom Vorwurf, streng geschützte Greifvögel mit Gift getötet zu haben, freigesprochen worden. Das Urteil ist nicht rechtskräftig. Der Angeklagte hatte sich nicht schuldig bekannt.

Wildtierkriminalität bleibt ein Dauerproblem in 🇦🇹: Im Mai wurden 3 vergiftete Rohrweihen & ein Kaiseradler gefunden. Der Angeklagte wurde heute freigesprochen. Es braucht jetzt einen Aktionsplan mit strengen Maßnahmen gegen Wildtierkriminalität! @birdlife.at​

🚨2025 #RedList Update🚨

We have reassessed 1,360 bird species. Out of the 11,185 species assessed worldwide: 

⚠️11.5% are globally threatened.

📉61% have declining populations.

But restoring habitats will help put these species on a path to recovery.🌱

Plastic pollution is widespread across the Amazon Rainforest’s rivers, plants and animals, according to a recent study.

To understand how and where plastic pollution is present within the basin itself, researchers looked at 52 field studies dating back to 2000.
