Mass Extinction From Pollution
From exploiting resources to spewing out pollution, humans could cause the sixth mass extinction. According to various estimates, up to 100,000 species become extinct each year and we could well join the list one of these years.
Super Volcanic Eruption
A huge super volcano in Yellowstone National Park could erupt at any moment. It could obliterate America and coat the world in a highly toxic ash cloud.
Man versus Machine
We're swiftly moving towards artificially intelligent robotic era. If at some point, these robots develop self-preservation and start seeing us as threats, man versus machine could happen.
Gamma Ray Explosion
When stars collapse, gamma ray explosions take place. One such burst would fry out mother Earth. It is incredibly rare, as it happens a couple of times every billion years but not impossible.
Bee species are at risk from rising temperatures and the use of pesticides. One-third of all our food depends on bee pollination, so their extinction could cause a major food crisis, which in turn could jeopardize human life.
Spread of Deadly Pathogens
Synthetic biologists work regularly with deadly pathogens. In the event of an escape we would be helpless against the spread of a disease like the Ebola virus.
Effects Of Co2 Emissions On Marine Life
Co2 emissions have increased the acidity of the ocean by 25% in the past two centuries. This could result in the mass extinction of marine life.
Mass extinctions have coincided with Earth's path through clouds of comets. Happening every 36m years, we are close to another, potentially triggering apocalyptic comet showers.
Scientist James Hansen claims burning fossil fuels will create a runaway Greenhouse effect. He points to Venus' temperatures as an indication of our future.
Earth's magnetic fields could flip at any moment, becoming weaker during the change. This will leave Earth unprotected and humans exposed to lethal cosmic radiation.
