    I'm sorry to hear that. How do you post to this forum?

    I hope you're getting some help. Nothing is so bad that you should kill yourself.

    May I ask why? What have you done?

    I think natural causes will be the reason for human extinction just as it has been for every other animal.

    Humans seem to have been, and continue to be, the cause of the extinction of many animals.
    Do you think natural causes are the reason for these extinctions?

    "It's frightening but true: Our planet is now in the midst of its sixth mass extinction of plants and animals — the sixth wave of extinctions in the past half-billion years. We're currently experiencing the worst spate of species die-offs since the loss of the dinosaurs 65 million years ago. Although extinction is a natural phenomenon, it occurs at a natural “background” rate of about one to five species per year. Scientists estimate we're now losing species at up to 1,000 times the background rate, with literally dozens going extinct every day [1]. It could be a scary future indeed, with as many as 30 to 50 percent of all species possibly heading toward extinction by mid-century [2].
    Unlike past mass extinctions, caused by events like asteroid strikes, volcanic eruptions, and natural climate shifts, the current crisis is almost entirely caused by us — humans. In fact, 99 percent of currently threatened species are at risk from human activities, primarily those driving habitat loss, introduction of exotic species, and global warming[3]. Because the rate of change in our biosphere is increasing, and because every species' extinction potentially leads to the extinction of others bound to that species in a complex ecological web, numbers of extinctions are likely to snowball in the coming decades as ecosystems unravel.

    My point would have been more accurate I suppose if I had said that I think humans will become extinct just like many other animals, by natural events.

    I don't think humans are going to blow up the planet with nuclear weapons to the point where humans become extinct. I think the greater risk is just the natural warming of the planet which will occur as the Sun burns more and more hydrogen.

    I'm not discounting any negative climate changes that are caused by man and I'm not discounting any species that go extinct due to man's "development" of their environments.

    I'm all for man being responsible in "his" stewardship of the planet. I'm not too concerned if man becomes extinct in a billion years (or in millions of years). It is what it is. Earth itself will survive longer but at a certain point it will cease to exist and life will cease to exist long before that.

    I don't know what that means.

    https://en.wiktionary.org/wiki/grok
    " Coined by Robert A. Heinlein in his novel Stranger in a Strange Land (1961)...to understand (something) intuitively, to know (something) without having to think intellectually...To fully and completely understand something in all of its details and intricacies...Grok is used mainly by the geeksubculture, though it was heavily used by the counterculture of the 1960s, as evidenced by its repeated appearance in Tom Wolfe's “The Electric Kool-Aid Acid Test.” "

    or
    perhaps some chemical created and unleashed by our industries will disable cps6?
