What would happen if every single person on Earth simply disappeared?

Not dead, simply gone, just like that. How would suburban pets fare without people to feed them? How would the forests, the oceans and the wildlife react if there was suddenly an end to all the hunting, fishing and farming? After being on the receiving end of humanity for millennia, nature would finally be given a chance to take the world back. But how would it work? How long would the skyscrapers and houses last if they were abandoned? 

Aftermath: Population Zero - The World without Humans

This is a fascinating documentary. It's quite long, but extremely interesting. What would happen if, tomorrow, every single person on Earth simply disappeared? “Aftermath” is the astounding story of a world that humans will never see. The two-hour special examines the impact of human beings on this planet by proposing what the Earth might be like without people.

  • "MY understanding",

    The world existed before humans, evoloution of species took its course based on the survival and instinctive need to keep their own particular species in existance.

    However, All species utilised each other to co-exist and adapted and evolved with each other to do this, hence they lived in balance. For example, (for which there are 1,000's) certain species of fish will swim with sharks, cleaning their gills and feeding from plancton gathered around the gills, the shark will not attack or eat them, because it is completing a task that is essential to the shark, in return the cleaner fish gets protection from a large preditor, which in turn ensures its own survival.. Blance!

    Likewise, there are species of trees that when attacked by for example an infestation of greenfly or mites, actually change there perfume to that a similar scent to a ladybird, which attracts the ladybirds to the tree and they consume the infesting attackers. survival and Balance for both..

    The world is such an amazing and complex place, the only species that do not work in balance is the human species!

    If they were not here, the world would continue, it would adapt and heal and re Balance!!

    The skyscrapers etc, would eventually be crumbled to dust as the flora takes over, you can see this, if you ever noticed an old house that has not been lived in for years has been consumed by plant life... Yo may have even noticed in very od places, little shrubs or grasses growning from very tall buildings, on the outside, the were not planted there by humans! that is nature, survival, continuation of its species!!

    Im sure the world will continue! There is so, so much amazing things going on around us every moment of the day that we just dont see or want to see!! What an amazing place we live, but fail to co-exist with it!

    (I do understand that a lot of people DO co-exist with it)

  • no one cant predict which animals/plants would survive and which would die as the ecology would shift between several solutions before arriving at a final settled state. The chicken is a real candidate for world dominance/survival because we have spread them so widely. They are really good at what they do Chicken.

    they, are relatives of the dinosaur after all Lizard

  • Apologies, with regard to your query to the suburban pets, they have a natural instinct of survival, this would be returned to them, as it was the humans that took these away, but they would be fine, just a lot more of them!!!!!
