      Sadly, the human race at the moment is beginning to create real problems for itself and I see three options for the future based on this question and two of them aren’t good for us…

      The planet will heat up due to greenhouse gases in a chain reaction that releases more and more carbon dioxide as the planet heats up, which makes it heat up more. If this gets out of hand, plants will die and we as a species will eventually die out ourselves. At this point the cause of carbon dioxide may have gone and maybe new plant life will gradually reduce the amount of carbon dioxide in the atmosphere turning the earth into something like it was before humanity evolved.

      Alternatively the same thing as above but the effect will keep snowballing making the earth into a furnace like planet with an atmosphere so thick and dense that it could crush things. This is what the surface is like on Venus at the moment!

      The third solution is a good one. We should take real action to stop global warming and stop (or maybe even reverse) the planets heating… Because sadly (on the second part of your question) … There is no where else for us to go yet… We don’t have the technology.

      It’s a really good question! Some people think we’ll head off to Mars (ever seen the film Total Recall?) but that has a lot of problems, the first one being the months in space it takes to get there, never mind the technology needed to live there.. I think what is likely to happen is not that our atmosphere becomes unliveable, but that sea level rises, fields of crops become deserts, vegetation dies out- I reckon that in these conditions, although millions of people would be in peril, pockets of humanity would still survive. Perhaps some would take to caves and live on mushrooms grown in the dark… (people in Cooper Pedy in Australia live underground to escape the heat of the desert). My hope is that we would adapt. 74000 years ago a massive eruption from a volcano called Toba wiped out almost all humans on the planet. But still, we survived and continued. We’re pretty resilient and adaptable as a species… so maybe we’d make it through “the fall” and start a new way of living!
