Ever since time began, people have tried to predict how the world would end.
Now we have one such prediction staring us in the face that can be one of the final nail in our coffin.
It is not an #all-out-war – #bomb – #terrorists attack – #neglect from our #politicians or any other #human-error. It may be #epidemic/virus/pandemic.
Some viruses may have evolved from bits of DNA or RNA that “escaped” from the genes of a larger organism. The escaped DNA could have come from plasmids (pieces of naked DNA that can move between cells) or transposons (molecules of DNA that replicate and move around to different positions within the genes of the cell).
From catastrophic climate change to hostile aliens, Hollywood routinely envisions apocalyptic endings to humanity’s stint on planet Earth.
From pandemic fungus to robot insurrection, here are 9 apocalyptic visions that scientists foresee. [Doom and Gloom: Top 10 Post-Apocalyptic Worlds]
1. Global warming
The mother of all apocalyptic fears, climate change is the biggest threat facing the planet, many scientists say. Climate change could make extreme weather more severe, increase droughts in some areas, change the distribution of animals and diseases across the globe, and cause low-lying areas of the planet to be submerged in the wake of rising sea levels. The cascade of changes could lead to political instability, severe drought, famine, ecosystem collapse and other changes that make Earth a decidedly inhospitable place to live.Volume 0% PLAY SOUND
It’s the mainstay of disaster movies, but scientists are legitimately worried that a space rock could wipe out Earth. A meteor impact probably doomed the dinosaurs, and in the Tunguska event, a massive meteoroid damaged about 770 square miles (2,000 square kilometers) of the Siberian forest in 1908. Even more frightening, perhaps, is that astronomers only know about a fraction of the space rocks lurking in the solar system.
3. Pandemic threat
New deadly pathogens crop up every year: Recent pandemics have included outbreaks of SARS (severe acute respiratory syndrome), bird flu, and, most recently, a coronavirus called MERS that originated in Saudi Arabia. And because of our highly interconnected, global economy, a deadly disease could spread like wildfire.
“The threat of a global pandemic is very real,” said Joseph Miller, co-author (along with Ken Miller) of the textbook “Biology” (Prentice Hall, 2010).
4. Fungus among us
Though bacterial threats are dangerous, fungal threats are even scarier, said David Wake, curator at the Museum of Vertebrate Zoology at the University of California, Berkeley.
“We’ve had a new amphibian fungal disease that has just had devastating effects,” Wake said of the chytrid fungus that is wiping out frogs across the United States.
An equally fatal fungus in humans would be catastrophic. And though bacteria are deadly, antibiotics are plentiful. By comparison, we know much less about treating fungal infections, Wake told LiveScience.
5. Engineered disease
Natural diseases aren’t the only ones to fear.
In 2011, the scientific community was outraged that researchers had engineered a mutant version of the bird flu H5N1 that was transmissible in ferrets and transmitted via the air. The results sparked fears that engineered deadly diseases could inadvertently escape from the lab or be intentionally released, leading to a global pandemic.
6. Nuclear war
Many scientists are still worried about the classic end-of-the-world threat: global nuclear war. Beyond North Korean leader Kim Jong Un’s saber rattling and Iran’s secretive nuclear efforts, massive stockpiles of nuclear weapons around the globe could wreak destruction if they were to get into the wrong hands. Last year, the Bulletin of the Atomic Scientists, a nontechnical magazine on global security founded in 1945 by former Manhattan project physicists, moved the Doomsday Clock, at five minutes to midnight. The Doomsday Clock shows how close humanity is to destruction via nuclear or biological weapons or global climate change. [7 Strange Cultural Facts About North Korea]
7. Robot ascension
“The Terminator” may be science fiction, but killing machines are not far from reality. The United Nations recently called for a ban on killer robots — presumably because experts worried that several countries were developing them.
Many computer scientists think the singularity, the point at which artificial intelligence overtakes human intelligence, is near. Whether those robots will be benevolent helpers or the scourge of humanity is still up for debate. But a lot can go wrong when there are hyperintelligent robots armed with lethal weapons running around.
The fear of an overpopulated globe has been around since the 18th century, when Thomas Malthus predicted that population growth would cause mass starvation and overtax the planet. With the global population at 7 billion and counting, many conservationists think population growth is one of the key threats to the planet. Of course, not everyone agrees: Many think population growth will stabilize in the next 50 years, and that humanity will innovate its way out of the negative consequences of the overcrowding that does occur.
9. Snowball effect
Though each of these scenarios could happen, most scientists think a snowball effect of multiple events is more likely, In other words, an accumulation of different scenarios combined together that nail the lid on mankind shut. Miller said. For instance, global warming could increase the prevalence of pathogens while also causing widespread shifts in climate. Meanwhile, ecosystem collapse could make it slightly harder to produce food, with no bees to pollinate crops or trees to filter agricultural water. So, instead of an epic catastrophe, several relatively small factors would slightly worsen life on Earth until it gradually degraded, Miller said.
All I can say is; those of us that think they are above it all – that think they can walk on water – that think they are better than everyone – think they are bullet proof should think again.
Just an example to show how insignificant we all are (butt many do not think so) ; the size of the earth has been compared to the rest of the universe is – ONE GRAIN OF SAND FROM ALL THE BEACHES IN THE WORLD. Now that is INFINITESIMAL.
If our planet Earth is that small, what does that make each and every one of us??
One of the major problems is; most people never think of what the future has in store. In their #greedy little minds, all they are concerned with is today and their own selfishness. Personally; I would like to make it a better world for my kids and their kids and their kids. Take a good look around; for the most part, that is not the road we are running down.
The Day is coming. When is anyone guess. It may not be next week or 1,000 years from now, BUTT it is coming. What intelligent people (the key word is intelligent) would do to extend that time out; is to do everything in their power to prolong the inevitable. Being the key word is INTELLIGENT; I would have to conclude, by the way we have abused Mother Nature and will continue to do so, the end may not be toooooo far off.
And NO; hiding under the bed will not save you.
A word to the wise should be sufficient – key word being WISE. With that in mind, mankind is screwed, blued and tattooed. We made our bed; now we have to hide under it, or something like that.
