When #marine animals ingest #DomoicAcid, they endure severe neurological symptoms such as seizures, disorientation, &, ultimately, death. These incidents often necessitate euthanasia due to the high mortality rates associated w/this toxin. This alarming rise in domoic acid poisoning cases not only threatens individual #MarineSpecies but also highlights the broader impacts #humans have on marine #ecosystems.

#Wildfires, including the #EatonFire & #PalisadesFire, have significant repercussions on #marine #ecosystems. The ash & debris from these fires can enter waterways & eventually the #ocean, altering nutrient levels & fostering conditions favorable to the growth of harmful #AlgalBlooms. The #toxic byproducts from these fires can exacerbate #OceanWarming, further promoting the frequency of these toxic blooms. This can lead to increased production of #DomoicAcid.

#DomoicAcid is a potent neurotoxin produced by certain phytoplankton species, which are significant contributors to harmful #AlgalBlooms. These toxins accumulate in the tissues of #MarineMammals & other #wildlife consuming contaminated prey. Recent changes in #ocean conditions,…intensified by #environmental factors such as the #EatonFire & #PalisadesFire, have accelerated the proliferation of these harmful algal blooms.

#Crisis On The Coast: #DomoicAcid Poisoning Strands 140 #SeaLions & 50 #Dolphins On #California Beaches
The recent influx of #marine #wildlife affected by domoic acid poisoning off the coast of Southern California underscores a critical #environmental crisis, w/≧140 sea lions suffering from this debilitating poison & reports of at least 50 stranded dolphins along local beaches.

we are living through an #ExtinctionCrisis unlike anything in human history—over a million #species are at risk of disappearing in the coming decades. #ecosystems that have taken millions of years to evolve are unravelling before our eyes, driven by #HabitatDestruction, #climate chaos, #pollution, and endless #extraction. every species lost is a thread pulled from the web of life, and sooner or later, that web collapses. ⁠

“It really shows that we have a unique place in #Michigan where someone has a chance to see a #wolf, a #moose & a #cougar in the #wild. It’s something that should be celebrated, that we have the #habitat to support an elusive animal like this,”Roell said.

The cubs were spotted & photographed without their mother. #CougarCubs are highly dependent on their mothers, often staying with them for the first two years of life.

Continued thread

This is the first time #CougarCubs have been verified since the big cats were hunted out of existence in #Michigan in the early 1900s, said Brian Roell, large carnivore specialist for the MDNR. Roell, a #wildlife biologist for 26yrs, led the team that verified the cubs.

“It’s pretty exciting, considering this could be the first known cougar reproduction in modern times in the western #GreatLakes states,”said Roell, referring to Michigan, Wisconsin & Minnesota.

Ecologists contend with the fact that many ecosystems we love and want to restore and rewild are in fact human-created ecosystems. Native plants in these systems are indeed native but selected by humans in human-created ecosystems. Which means insects, animals and other biota in those systems are influenced by humans.

We will never go back to pre-human ecosystems. Our world is shaped by our behavior. We depend on our world to survive. Our world depends on us to survive. We depend on each other to survive.

We are part of nature, we shape nature, we try to optimize it for our survival. We are natural beings. We are part of the world's ecosystems.

"Climate change is causing the world's glaciers to disappear at an alarming rate. Scientists have been studying and modeling this process for years, but until now, no research group has specifically examined how glacier melt will affect glacier-fed streams and their ecosystems".

and take this opportunity to lead in the transition to a #sustainable, low-carbon economy.

Rather than framing #climate #activism as a threat, your respective levels of government, including the provincial government, could respect the historic roles that civil society has played – and plays – in advocacy for necessary environmental policies that protect the physical and mental #health of people and our voiceless contemporaries throughout the #ecosystems on which our lives depend...
