Humans

                                                   What if all Humans Disappeared?

Friends, Have you ever wondered what would have happened if all humans Disappeared from the Earth? So, let's answer the extinct question, "What if all Humans Disappeared?" First, let's see what could make humans extinct.

Now a question might come to your mind, "Can humans ever go extinct?" Humans are inevitably heading for extinction. The fossil record shows that eventually, everything goes extinct. Almost all species that ever lived, over 99% are extinct. "The Neanderthals, The Denisovans, Homo Erectus, Australopithecus" are species that are all gone. 

Human extinction is the assumed end of the human species due to natural causes like an asteroid impact or large-scale volcanism or anthropogenic (human) causes, also known as omnicide.

There are five major causes of human extinction
1. Habitat loss
2. An introduced Species
3. Pollution
4. Population growth
5. Overconsumption

How much longer can we live on Earth?
The end of humans is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the plant's habitability. 

                                

                                   

Now let's dive into our main question "What if all Humans Disappeared?".We can say that 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. Within hours of our disappearance, the subways of huge sprawling cities like London and New York would flood. On the other hand, electricity all over the world will begin to shut down causing a partial black-out.

The only source of light will be 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. 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 long 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. Changing climates 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.

Comparatively, houses in villages will decay more slowly. But surely they will be infested by rodents, bugs, and other unwanted guests. Within 200 years most concrete structures will completely collapse and will wash away in running water. 

Within the next 700 years, the supporting pillars and foundations of these houses will be rotten collapsing and turning into rubles. While cities will be covered with wild and poisonous plants, like Ivy and hogweeds. As the drowned concrete will mix with waterways, it will increase its acidity, allowing new plants to grow and thrive. 

The impact of human extinction will also affect the animal world too. Many wild animals will enter our 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.

But still, it will be a lot of time before we go extinct. So we must enjoy the time of your life. Hope you liked the facts. Until next time.....................
