How Will The World End?

It's The End Of The World As You Know It:

There have always been doomsayers predicting the end of mankind. After all things went downhill for the dinosaurs pretty quick. When will it happen to us? And how?

Nuclear Annihilation:

Now that the Cold War is over and the USA and Russia are the best of friends, is Kim Jong-Un crazy enough to unleash his nuclear arsenal on the world?

Crushed From Above Somehow:

It's believed that the dinosaurs disappeared because of a huge asteroid. They died quickly in a massive heat wave caused by it and then debris entered the atmosphere blocking out the sun and causing a nuclear winter, finishing any stragglers off.

And all of this was caused by a rock thought to have been 5km in diameter!

In 2002 astronomers discovered an asteroid 2km wide that will have a near miss with the earth in 2019. Also in 2002 one 100 meters wide passed the earth even closer than the moon! If it had hit us it would have caused the destruction equivalent of an atomic bomb.


In the 14th century the Black Plague killed half of the population of China. Then it spread west to Europe. In total it may have wiped out as many as 100 million people. Could a global pandemic end the world as you know it? It's possible and even likely with diseases like Ebola being a major threat. 

Disease causing microbes, once thought to have been eradicated, are becoming drug resistant. Newer and stronger antibiotics are needed as they build up a tolerance to what is trying to kill them. This has been happening with the disease many thought was eradicated: Tuberculosis.

Once known as consumption it was only by the 1880s that it was realized to be contagious. Efforts were made for better hygiene and to put sufferers in sanatoriums. A vaccine was introduced and, while it was surprisingly slow to catch on, it became popular by the 1950s.

It's probable that 1/3 of everyone in the world carries the virus for TB. When someone in a rich country has an outbreak they are most likely tested to see if they have the drug-resistant strain. In poorer places they don't have the resources. India has about two million cases a year while China has one million. Recently what doctors call TDR TB (totally drug-resistant) has broken out in India and before that had been seen in Iran.

A disease that's spread through the air, the infection rates are high as one person can pass it on to hundreds.


Is the most expensive box-office flop the future of mankind?

Nope. Most of the ice in polar regions is floating so If the North Pole melts it will only replace the floating ice that it is displacing. And Antarctica is simply too cold to ever melt.The oceans are rising due to shrinking glaciers. So while places at sea level are in for flooding, Toronto will never be Waterworld.  

Death by Volcano:

Forget about all of the above. The real threat is the earth itself! Yellowstone National Park may be a nice place to take pics but it also has the power to wipe out all life on the planet. That's because it's a supervolcano. The geysers and hot springs that make the park famous are powered by a sea of magma thought to be 6 miles down and 30 miles wide and another 6 miles deep. And the even worse news is that the ground there has been slowly going up as pressure builds. One of the largest volcanoes there is, the last time it erupted was 640,000 years ago. Now many think we're overdue. If it goes off it could wipe out North America and launch debris into the atmosphere that would block out the sun. In 1816 a much smaller volcano went off in Indonesia sending an estimated 93 cubic miles of ash into the atmosphere. 1816 became known as the year without a summer as the earth's temperature cooled and farmers had little to harvest. People as far away as Europe starved.  

Alien Invasion:

For years we have been sending radio signals into space. Could unfriendly aliens be listening? The SETI Institute is even doing the possibly unwise thing of actively looking for these extraterrestrials.
