Sharks on brink of extinction caught in tangle nets in protected Irish waters "That the Irish Government still allows this form of destructive fishing throughout Irish coastal waters is an absolute disgrace" www.irishtimes.com/environment/...

#Ocean Does anyone think our commercial fishing practices are sustainable? Fundamental change is inevitable, and like the cop says, we can do it the easy or hard way. It can start now, phased in sensibly, or a bit later, by catastrophic collapse. Our stark choice.

‘Nothing left’: Irish whale-watching company closes amid ‘overfishing’
Sprat fishing has disrupted the food chain and diverted humpback, minke and fin whales as well as dolphins

#Ocean What have we done? A whale-watching company in Ireland has closed down permanently because huge trawlers have left nothing but "an empty, lifeless sea." All the dolphins and humpback, minke & fin whales have disappeared, leaving nothing left to watch. Source in 🧵

There is only one organization in the world dedicated to the Binturong. They do important work, inc teaching locals why it's against their interests to kill them for their skins, to eat, for TCM, or to trap as pets. They are desperate for urgent support if you can help: abconservation.org/en/ 4/4

Few animals suffer in more ways at the hands of humans than the binturong (Arctictis binturong). Facing national extinctions, not only from massive deforestation in SE Asia, but throughout their range they're eaten, skinned for fur, killed for TCM, trapped for zoos & trafficked as pets. 🧵2/4

#Asia This is a tragic image from Facebook advertising this binturong for sale as a 'pet' They are long-lived wild animals, completely unsuitable as pets, as our homes are not a forest, nor are we nocturnal, & imprisonment, deprivation of mate & family is cruel & decimating numbers in wild. 🧵1/4

#Climate An albatross chick lies dying in wet mud on Bird Island. The tall nest was specially constructed to protect them, but we’ve warmed the world. Winds are now stronger, so the chicks are blown out of their nests. A bird who lives on the wind is now dying by the wind.

No. Quite a few ppl do it, a good friend on X complained to a big account, someone one would never have believed would stoop so low, that he'd lifted his work & passed it off as his own, asked him to delete it, but no reply. That account (highly-respected wildlife activist) then did the same to me.

#StormÉowyn We can take refuge from extreme weather in our homes, but most wildlife suffers the full force. Seabirds are particularly vulnerable; puffins die in their thousands in powerful storms. A warming world is littered with their battered bodies.

#Biodiversity #Extinction On the left: the problem. On the right: the solution. When a species is wiped out, they won't care; we are the losers, and we need to start cherishing and protecting our fellow inhabitants of this planet as a priority, not an afterthought. Money won't bring them back.

What soybeans are used for: 77% of global soy is fed to livestock for meat & dairy production. Most of the rest is used for biofuels, industry or vegetable oils. Just 7% of soy is used directly for human food products, such as tofu, tempeh & soy milk.

You'll be glad to hear this bear was rescued, treated for injuries, and set free, but habitat destruction, hunting for TCM, killing mother bears for cubs for the pet trade & human/bear conflict as we encroach into their native territory means their numbers are decreasing.

Quote not by James Baldwin, but by Robert Jones Jr: "Thanks to my former Twitter alias, “Son of Baldwin,” something I said back in 2015 will likely always be misattributed to him and I don’t mind. After all, he’s given me more than I could ever hope to repay." www.nytimes.com/article/jame...
