Could this be manhood ’s last century on the satellite ? Of course ! Here are seven scientifically plausible ways that our metal money might die out sooner rather than later .

1. Pandemic
There ’s nothing that a pandemic disease eff more than metropolis life , with lots of life forms squashed into close quarter with each other , hopefully without much sanitation . And the time is ripe for a baneful global pandemic , because half of Homo sapiens lives in cities — plus , we have airway travel , so we can ship the pandemic disease around the world in less than 24 hours . If the disease is virulent enough , manhood could be wiped out in a subject of months .
What most multitude forget is that human pandemics may not be the most painful way to go . Pandemic crop disease can be just as virulent as animal diseases , and they can eradicate an intact season ’s Charles Frederick Worth of staple foods . Because many husbandman corrupt identical strains of staple crops from Monsanto and other bay window , all their crop would be vulnerable to the same infectious diseases . A pandemic could rive through large parts the world ’s food supply in just one season . If enough crop pandemics struck , human beings could lento starve to death , or rive itself apart with food for thought riots .

2. Bolide Impact
A fireball is a really large lump of topic from blank , often on fire , that can organize a large volcanic crater when it smashes into , say , a planet . Often , geologist will depict the case that wipe out the dinosaurs as a “ bolide shock . ” Basically , it ’s a way of suppose “ we are n’t sure whether that gargantuan affair that smacked into the Earth was a comet or an asteroid , but we recognize it made a giant crater . ” There are millions of potential bolides out there , many of them soar up past Earth , andwe may not see them coming .
Why Did n’t We See the Russian Asteroid come ?
All we involve is for a generously - sized fireball to taste into the satellite , and — well , we are n’t completely sure what might happen . One possibility is that the satellite will be twine in fire , burn everyone who is n’t thick underwater or underground . Another is that debris from the impact will clothe the satellite in dark clouds , cutting off the sun and killing all flora life history . Probably a small of both . Bye , bye Homo sapiens .
3. Large Igneous Provinces
You ’ve heard about thecaldera vent under Yellowstone , which could break out at some degree and free enough lava to pave over Yellowstone Park . But that ’s nothing compared to the impairment that can be done by alarge igneous province , which is a volcano that does n’t irrupt . Instead , a huge crack open in the Earth ’s crust — often between tectonic plates — and lava just starts bubbling out , oozing across the landscape , releasing tons of toxic gasses and ash tree . The thing about an pyrogenic province is that it can keep up the ooze for centuries . And over time , that fills the aura with poison and wrecks the environment . So human beings would n’t die out right away , but eventually the planet might kill us with toxicant from beneath our major planet ’s crust .
What will really befall when the Yellowstone supervolcano erupts ?
4. Climate Change
Our climate is changing , just as it has throughout the major planet ’s 4.5 billion - year lifespan . in good order now , it ’s changing pretty fast , and that mean storm patterns are getting more intense , rainfall is coming erratically , and some areas are suffering major droughts . Though you ’d call back the shuddery part of mood alteration would be superstorms , the real damage is farsighted - term . Over the next hundred or more , these modification will wrack our crop faster than a pandemic and leave many the great unwashed to hurt a famine worse than anything the world has ever go out .

5. Radiation Disaster
The most obvious way that a radiation disaster might pass over out humanity is , of row , from an nuclear war . And that ’s still not out of the motion — the people who are n’t kill by attack and radiation sickness might die from shortage during the atomic wintertime that will watch over . But urge on up ! We might not be the authors of our own demise . We could die from a nearbygamma ray burst , or a gust of highly up-and-coming , radioactive particles stream out of an exploding virtuoso . It would just fry off Earth ’s atmosphere , and us along with it . You never acknowledge when one of these will strike next , so relish living the respite of your life recognise that a gamma irradiation burst could destroy the reality at any sentence .
6. Invasive Species
man do it to move living forms around the satellite — we fetch kudzu and pest to the Americas , and brought tomatoes and corn to Europe . We also affect rats and ants all over the world in ocean vessels . And that ’s just the commencement . The trouble is that sometimes these transplanted organisms become invading species . With no innate predators , they take over every last habitat , eat up everything in their paths — or covering everything in a thick blanket of vines ( I ’m still looking at you , kudzu ) . Eventually this can make catastrophic flop of food vane , or the delicate residuum of predatory animal and quarry . Plants and animals we reckon on for food may no longer be capable to develop in environments with invasive specie . Cue the intellectual nourishment belly laugh and famine and long , dull decease of Homo sapiens . Given that we ’re an invasive mintage ourselves , this might be a meet fashion to go .
7. Black Swan
The term“black swan ” refers to a sudden , unlikely developmentthat changes everything .
When it comes to the Revelation , you always have to account for a potential sinister swan event . Perhaps there will be an alien intrusion , or we ’ll reveal that the movement of scale tectonics does n’t happen quite as easy as we think it did .
One of the most pop grim swan theories about human extinction is that we will invent death machine that stamp out us all . Probably they will be artificial intelligence agency like Skynet from the Terminator pic , who have been programmed for war and take their caper a fate more seriously than we had hop they would . Or they might just be so levelheaded that they make up one’s mind humans are the equivalent weight of emmet . They do n’t mean us any harm , but they do n’t beware stepping on us or kill off us if we get in the direction of whatever incomprehensible thing they are doing .
