    Humans and supervolcanoes. When Yellowstone blows it's game over form humanity.

    But, seriously, a pandemic is the most-likely destroyer of mankind. Especially amid the rise of globalization. Airborne ebola with a longer incubation period could ruin us. But, more likely, it would be some virus we haven't even encountered yet.

    Re: Greatest threat to this planet.

    Btw, as soon as I (and my loved ones) are dead - the planet can go bye bye for all I care (though I do not wish for it to happen).

    Humanity seems like a rather useless species...I highly doubt the universe will miss us.

    In fact, I think it would probably be better off without us.

    But, maybe humans will evolve enough someday so as to be useful instead of useless...but I doubt humanity will last long enough for that to occur.

    Nuclear warfare actually. The "dangers" listed are either too mild or too unrealistic to be considered valid threats.

    Re: Greatest threat to this planet.

    The rock we live on can probably be destroyed only from the impact of a meteor or other large object.

    All life on earth could be destroyed by anything, natural or man-made, that prevents the reception of the sun's essential waves/particles or that causes the poisoning or other significant harmful change to the composition of the air and water. That could be caused by a huge volcano or by our actions. It is most likely to happen during a war, especially if a large number of nukes are used.

    The destruction of all humans is more likely than the destruction of all life because human's are dependent on many natural systems continuing to function as they have been.

    One of the most likely scenarios for the end of human life is over-population causing continuous and excessive poisoning of the air and water with associated atmospheric changes causing a reduction or change to the sun's waves/particles and those changes killing us by poisoning or with cancer.

    The other most likely scenario is large scale nuclear war (which is more likely with over-population) killing off all humans with both the initial heat, shockwaves and collapsing structures followed by the cancer death of the survivors from the bomb's radiation or from the changes to the sun's waves/particles caused by the nuclear explosion impacting the protective atmospheric layers.

    Even with an extremely cataclysmic event it may happen that all humans will not die, instead the survivors may return to a more primitive dark ages style of living with little technology available.

    Re: Greatest threat to this planet.

    What if, because of medical science. Genetic problems like diabetes that would otherwise not be viable, become normal. This could eventually cause a reliance on technology and drugs that Any disruption of energy supplies could stop, killing off multitudes like a great plague. Seems far fetched...... But is it? Diseases that would have killed children until this century can now be managed in a way never before possible. As long as we have medical science, no problem but a serious blackout worldwide could be more than just inconvenient.
    You can't reason anyone out of a position they didn't reason themselves into in the first place.

    The universe as a whole and/or other species on other planets (assuming they exist).

    Besides, other then slowly destroying the planet and causing great misery for huge numbers of people, I don't see a great point to humanity's existence at this point in it's evolution. Though it seems to be INCREDIBLY, slowly improving.

    No doubt many/most do not agree with me...I don't much care.

    Re: Greatest threat to this planet.

    Lots of people who are simply unnecessary to keep the economic engines humming. That will be the great challenge for the 21st century. What do we do when a full quarter... or a third ... or even half the people are no longer necessary to employ to produce all we need? What happens with those people and how does it change both our social fabric and our political fabric?
