What If All Humans Disappeared? | Human Extinction | The Dr Binocs Show | Peekaboo Kidz

thank goodness it was just a bad dream what happened well i saw a nightmare in which the alien robots attacked the earth and wiped out human existence then well let's discuss that in detail with a lovely audience hey friends so in today's episode let us explore this undesired situation and answer a hypothetical existential question what would happen if every human suddenly disappeared zoom in [Music] well if humans went extinct the first thing to go for a toss will be the power plants and drainage system as there won't be anyone to run and maintain them so within hours of our disappearance the subways of huge sprawling cities like london and new york would flood and on the other hand electricity all over the world will begin to shut down causing a partial blackout the only source of light will be the flames blazing from the malfunctioned oil refineries burning for weeks and even months with no firefighters to put the fire down it would spread across the surrounding region and might end up harming domestic animals breaking out as there will be no more electric fences to control them and once the burning factories extinguish the earth will go dark again after many many centuries after the first chaotic month changes will occur slowly and by the next 20 years or so the streets will be engulfed in weeds and torn apart by tree roots at the same time the water from the flooded tunnels and subways will rise up on the roads eroding and turning them into rivers and changing climate like winter and summer will freeze and melt these waterways causing cracks in roads and buildings that will shatter their foundation as they will begin to decay and within 200 years most concrete structures will completely collapse and wash away in running water [Music] comparatively houses in villages will decay more slowly but eventually they will be infested by rodents bugs lizards and other unwanted guests and within the next 70 years the supporting pillars and foundations of these houses will be rotted collapsing and turning into rubble on the other hand cities will be covered with wild and poisonous plants like ivy and hogweeds meanwhile as the drowned concrete will mix with waterways it will increase its acidity allowing new plants to grow and thrive not only that the impact of human extinction will reach the animal kingdom too many wild animals will enter a blighted cities with the help of leftover passages and bridges insects like cockroaches have been here since the dinosaur era and will continue to thrive but their urban cousins won't survive the post-human world more than two winters due to lack of a heating system however due to the increase in trees and animals the earth's climate will start to recover from the damages caused by human activities and it may take another 65 000 years for carbon dioxide to return to pre-human levels and it won't be wrong to say that without humans our planet would ultimately be fine and thrive [Music] your time did you know 50 percent of the planet's land mass has been transformed for human use [Music] also worldwide 12 percent of mammals are threatened with extinction hope you learned something new today until next time it's me dr by nox zooming out [Music] never mind
