Around 70,000 years ago the volcano Toba in Indonesia erupted and covered the earth with so much ash the sun was dimmed for 6 years. If this happened again would we survive?

  • We will survive

    We will survive because if the ashes just dimmed the sun plants and crops won't grow the fastest but our water supply won't evaporate the fastest either, we can live without sunlight dimmed a little but the growth of the population will increase, people with Erythropoietic Protoporphyria won't have to worry about the sun that much.

  • Most people would die but the human race could survive.

    Mass starvation would result killing the a large section of the population but there will be groups who have enough food stored to last 6 years and seed vaults will allow us to restart civilisation. With sufficient power you could also use hydrophilic farming with an artificial light source to provide a reasonable amount of food, no where near as many as people who live here now but still easily enough to ensure that there's plenty of genetic diversity.

  • We already did.

    Humans were around 70,000 yrs ago and though drastically reduced in numbers continued to survive. If the sun ever goes out, move to iceland...They'll be harnessing the geothermal heat that will exist for millennia after the earth surface temperature drops to unlivable conditions for the world. Not a likely scenario for 70 billion years i think.

  • Yes, i believe so

    We are more technologically advanced. There is no doubt that we will overcome the catastrophe in a matter of days if not hours. We are living in the 21st century, we are the most advanced species on earth. We will always overcome, that is how we managed to make it this far. It might be difficult and uncomfortable, people might take advantage but we will survive.

  • Humans would survive with dimmed sun for 6 years.

    Humans as a whole would be able to survive in a situation with dimmed sun for years on end. We have the technology to ensure that there would be enough food to sustain the population and vitamin D supplements. However, there would be many negative side effects environmentally as natural areas may not have enough sun to thrive.

  • Well, I hope so we will..

    I suppose it is imperative to point out that those nearest to the volcano erupting would certainly perish. But the dimming of the sun is problematic, not fatal. There are technological workarounds and adaptations to agriculture that would help sustain life, though perhaps not quite as we know it today.

  • It can't be any worse than global warming

  • The sun is why we live.

    We need to develop a plan for what to do if Toba erupts again, there's also a volcano like this in Yellowstone that could block out the sun. Without the sun, nothing can grow, and if nothing can grow, nothing can live. This would also cause a volcanic winter, these events would kill most if not all of the planet's life before the sun could shine again.

  • Humanity cannot survive such a globally catastrophic event.

    The dimming fo the sun for that amount of time would wreak havoc on the environment and the systems upon which we rely for food, power and business. Some outcroppings of the human race may be able to live in a similar manner as they do now, but mist of humanity will perish as we no longer have the survival skills and adaptability that we once had. Besides,the consequences of such an event would be so catastrophic that hardly anyone would want to survive.

Humanity as a whole might survive, but only by sacrificing a massive portion of the population. The deaths may well result in the loss of many parts of our society and knowledge, but I think the race itself would survive.
