Life After People (Part 3)

One hundred and fifty years later, the buildings especially the high buildings will become a vertical ecosystem completely. Cats will be a ruler on the top of the cities. The cats may be evolution to some kinds of animals that can fly as the flying squirrels. On the land, the wolves will hybridization with dogs. The large predators will appear everywhere. The life in the ocean will resume quickly without the garbage and hunt like what happened during the World War 2. Great amount of seagulls will die without the landfill. They have to feeding in the natural way.

Two hundred years later, The Eiffel Tower and the Jin Zu railway viaduct that have the same structure with steel and built in the same period will fall down in sections one by one by the strong wind.

In one hundred year to three hundred year after people disappeared, the whole world will become to a large collapse times. The skyscrapers include the landmark buildings will all collapse.

Five hundred years later, all of the steel will rust and even all of concrete will be broken.

One thousand years later, the cities will disappear completely. Some of the roads will become to rivers and streams by rain and snow. The water system will be rebuilt. May be there will appear some hills.

Ten thousand years later, the radio waves and the sign of TVs will become to noise and go on forever. Some ancient buildings like the Great Wall and the pyramids may be still exist. The stone statues on the granite like the President Hill in America will be eternal in the world. The orangutans will evolution to the intelligent beings like humans. They will take humans’ place and be the dominate in the world.

Life After People (Part 2)

Five years after, the world will be covered with green. The whole world is a nature. The trees and the grasses are growing, the animals will come back, all of these just like a big forest.

Twenty years after, all the things will come back to the original. The animals that are in the zoo will escape or die. The plants grow in the crack at the wall in winter, the water in the plants freeze and let the crack expand gradually. The plants also root on the foundation make the pressure of the building is increase. At last, the buildings made by concrete will be decomposed. The birds will nest in the buildings. There have a real place that you can see and feel the situation in our world. The Soviet nuclear leak was happened twenty years ago. In that place, the people have lift since 1986. The facilities rust, the whole things are corroded. But unfortunately, the unclear leak killed the most plants and animals in 1.5 km.

Twenty-five years later, the humans’ footprint will disappear. There has another serious problem that the flood protection will stop. Some of the cities are lower than the normal level where like London and Amsterdam. They will flood and disappear forever. The glasses of the buildings will be broken, the lightning rods rust either. When the summer storm comes, the lightening will let the cities in the flame. The pigeons will life in the buildings. The wolves are rising rapidly without being hunted and they will rule the mainland.

Forty years later, the buildings made by wood will have the biological erosion like termites, burn and chemical attack. All of these will let the buildings destroy. The buildings made by stone or granite will be attacked with weathering and salts except the buildings in desert. The monument will have the same situation without repairing and protecting. The dams will fall down, the flood will destroy everything that it has passed. The paint of the cars will fall and the cars rust. The cars more closer the sea, will rust more faster, the cars more closer the desert, will rust more slower.

Fifty years later, the Brooklyn Bridge and the Golden Gate Bridge in San Francisco will begin to have the oxidation erosion. The cables of the bridges have 98% iron. They will rust gradually.

One hundred years later, the Brooklyn Bridge and the Golden Gate Bridge will fall down to the riverbed by the 1/3 cables fracture. Some important paper files in strongboxes will be destroyed without power. The temperature and the humidity of the strongboxes will get higher and higher. The videotapes and the photos will seethe. The microorganism will have large growth with high temperature in the library. The digital media likes DVDs and VCDs will disappear. It is so laughable that the advanced technology is defeated by the painting on the stones which made by the ancients.

Life After People (Part 1)

Have you think about the happen when there is no any people in the world? What will happen at the age of population zero? We don’t know how human beings become extinct. But we can imagine the world without human beings in science.

In this age, time is no use. In few hours, 70% power plant using coal and carbon will closed without people work. Most of lights will off in the world.

Two days after, the nuclear power and wind power without people work will closed too. All the electricity will be broken off except the southwest of USA. All of the place will in the dark except Las Vegas. There will have the only lights all over the world. The Hu Fee Dam works by hydropower will de the last working power plant in the world. The system about electricity will collapse. The pumps pump water keep the tunnels out of flood will be stopped. The groundwater will rise and flood the tunnels.

One week after, the food in supermarket and in refrigerator will rot. The dogs as the pets will die because of starvation and fight. The kinds of the dogs and the survival skills they have that is an important factor to let them survive.

Few weeks after, the rats and the cockroaches will eat all the food which human leave. The rats will come back to the nature. They will be preyed by other animals and the number of the rats will reduce. The cockroaches will eat the books, papers and woods. But they are the tropical animals. They will die great amount without human beings in the first winter. The pest will in the prime age without pesticide.

Six months after, the cities will become to a wilderness, the small predators will come back to the cities.

One year after, the most physical effect is the plants. The plants will grow up and spread. They can destroy everything in few years. At first, they will grow up and wither. The moss and lichen will grow up. Then they will change to be the dust and cover all the grounds. Some plants will spread on the wall. They let the wall pressure increase. Finally, the wall will fall down. The lightning also makes the forest on fire. It burns the threes and also the buildings by wood. All of these will become to the nutrient. The Hu Fee Dam will be covered with microorganism. They will block the cold water pipes without cleaning. The pipes will overheat and let the generators closed. All the electricity is gone in the world. There are no more lights at night. The upper reaches of the Hu Fee Dam will arrive to the discharge point and the lower reaches will become dry.
