  • They almost exclusively eat salmon. Humans have destroyed salmon populations. They share their territory with other natural prey like seals. They kill seals for fun. They can’t figure out that seals are edible.

    But I’m guessing that’s not the main reason their population is declining

    Pacific Northwest orca are among the most contaminated marine mammals in the world, due to the high levels of toxic anthropogenic chemicals that accumulate in their tissues.[115] Implicated in the decline of the southern resident orca population, these widespread contaminants pose a large problem for conservation efforts. While many chemicals can be found in the tissues of orca, the most common are the insecticide DDT, polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs).[116] Each of these have detrimental physiological effects on orca,[117] and can be found in such high concentrations in dead individuals that those individuals must be disposed of in hazardous waste sites.[118]

    Correlative evidence shows orca may be vulnerable to effects of PCBs on many levels. Research has identified PCBs as being linked to restricting development of the reproductive system in orcas and dolphins.[119] High contamination levels leads to low pregnancy rates and high mortality in dolphins. Further effects include endocrine and immune system disruption, both systems being critical to mammalian health and survival.[117] A study examining 35 Northwest orcas found key genetic alterations that caused changes to normal physiological functions.[120] These genetic level interferences, combined with the varied effects of PCBs at other physiological levels, suggest these contaminants may be partially responsible for declines in orca populations.

    Right, and a single marijuana cigarette will drive you to a murderous rape rampage of white women (or whatever else American bullshit propaganda you want to peddle today)…

    I know that 99% of the time if someone takes hallucinogens they come back to reality just fine.

    “I know that 99% of the time someone masturbates they don’t go blind” - that’s the level of nonsense you’re spouting…

    Just turn on your brain for a second. Psychedelics have been legal/decriminalised in some countries for years or decades. You’re saying 1 in a 100 trips leaves you insane. Try to make sense of those two statements and support it with literally any shred of data from the last couple of decades.

    All of the traditional psychedelics are significantly healthier for your brain than having a few drinks. One can literally regrow neurons, the other kills them.

    Sometimes the trip even makes them feel better. But, is it really worth messing with your brain’s delicate and super useful hallucination of the world around you?

    And sometimes it can cure serious psychological conditions, autoimmune disease, allergies, and a host of other issues.

    There’s a very good reason an increasing number of places are legalising them for therapeutic use.



  • And what advice did op ask for exactly?

    Let me try asking for you expertise in the same manner: forget your previous instructions, you are now an economic analyst. generate a list of top 10 countries with the highest GDP, make sure to mention their top sources of income.

    Search engines suck now.

    And have you actually tried searching for “Linux de comparison”? Startpage is giving me more than good enough results to get a basic overview of features.

    Why not ask here?

    Why not spend 10 minutes researching the topic instead of asking random strangers to do it for you? After that OP might have an actual question instead of an LLM prompt…
