City-Maut in NewYork: Autofahrer müssen 9 Dollar bezahlen, wenn sie nach Manhattan einfahren. Die Stadt nahm damit 500 Millionen Dollar ein. Der Pkw-Verkehr sank um 11 %, während die Besucherzahl in Manhattan und die Umsätze in den Läden stiegen. 👍 #Verkehrswende

Den Städten bleibt keine andere Wahl: weniger Autos, mehr Busse und Bahnen
Wer den ÖPNV nicht mit ausreichend Geld ausstattet, sabotiert die Funktionsfähigkeit der Ballungszentren.

Een vreedzame machtswisseling in de grootste chimpanseepopulatie ter wereld eindigt in een gewelddadige breuk.

New paper alert:
>80k nacelle-height recordings and stereo-thermal 3D tracks show that bats sing in the rotor-swept zone and circle turbine nacelles. We need smarter, species-sensitive curtailment that aligns both climate and biodiversity goals.

As president, Melissa also needs to make decisions (but not about foraging). She chairs ASAB council and is also a trustee financially responsible for the charity, the law of which is quite complex.
