This book from the 19th century depicts the Rhine Valley by creating an impression of three-dimensionality and spatial distance

Seriously, what do you think are the long term prospects for a species that routinely engages in such pointless atavistic savagery against the living world – and one another? (Faroe Islands, yesterday)

aggressive reminder that insects, fairy shrimp, remipedes, and now copepods too (!!!) are a clade of crustaceans called Allotriocarida or literally "weird shrimp". Bugs is shrimps, by definition

Best practices in #taxonomy are critical for addressing the current #biodiversitycrisis. Taxonomy needs to be rebranded to the scientific community as a modern, active and important discipline with sufficient funding and taxonomic researchers. #Entomology #Zoology #Museums

Lätt att glömma hur viktig allemansrätten är inte bara för miljön, utan också för folkhälsan. Därför är varje lättnad av strandskyddet en riktigt dålig idé. Dessutom ett oåterkalleligt beslut för generationer framöver. @annieloof @Centerpartiet aftonbladet.se/nyheter/a/56m…

Thanks @outsidemagazine for featuring this to your 353000 followers. The way forestry is carried out is an ongoing mega-scandal and Sweden's by far most severe environmental, climate and biodiversity catastrophy and a disaster for the countryside.@bolund @martastenevi @SwedishPM
Glad to be featured by @outsidemagazine’s Instagram page today for my National Geo/Yale project about the irony of Sweden’s unsustainable policy of clearcutting their most ancient boreal forests for paper products etc, see the photo set here: instagram.com/p/CN-geYDAXdL/…

All the #winning 🤷🏻‍♀️ Imagine the resources thrown into this joke of #Brexit The amount of disinformation and make-believe peddled. The UK was a fabulous partner inside the EU, making all of us stronger at the same time benefiting from us all. Now. This.

Lodjursjakten började idag. Enda skälet att den ens är laglig är att Sverige rapporterade fel antal lodjur när vi gick med i EU. Ren troféjakt, vore det något annat skulle länsstyrelsernas folk skjuta utvalda djur själva. Sverige halkar efter i naturvård på alla fronter.

This is a 392 year old Greenland Shark that was recently discovered in the Arctic Ocean. This guy was wandering the oceans back in 1627.
