This chapter talks about what will happen to our vehicles and other machines that run on petroleum gasses. How long it will take to decay, how it’s spread all over the world, how the oceans are filled with it, and what it’s effect will be on wildlife. Other things will be covered by land and buried until something unearths them. In this part of the book the author investigates what will last after we’re gone. It gives examples like an abandoned hotel to show how relatively quickly things will change. This chapter speaks of how our buildings and land will change after we leave. It talks about how after we’re gone, animals may double in size or go entirely extinct. This section of the book talks about how there is still megafauna in Africa, but pretty much nowhere else in the world besides the water. This chapter also explains how chimpanzees are like us and how we came to be.Ĭhapter 5 talks about what we did to the animal populations as we spread throughout the world, and what will happen to them after we leave. It will take 100,000 years just for CO 2 levels to return to the way they were before we came along. The atmosphere will be very different when we're gone- and most of it is our fault. The next ice age is coming later than expected. Things will crumble because of water and the city will eventually be retaken by nature. Meanwhile wildlife will be taking back it's habitat. After we're gone they'll erode away the subways and road will cave in. The subways hold nearly 13 million gallons of water daily, and they have special dams that people have to monitor every time it rains or else the subways will flood. New York City will literally go down the drain during the first rainfall after we're gone. It's hard to imagine the world without us. After we're gone, the Earth will essentially go back to the way that it was before us. We used to build structures that were much sturdier, but our impatience has caused us to build with materials that are faster to place, rather than sturdier. Nature may leave parts from machines, maybe from your house, or nothing at all. After 500 years, what's left depends on where you lived. Your home will last maybe 50 years, 100 tops. Then, the animals will come in, and start to add on to the disaster, chewing, nesting, etc. Nature wants "revenge," so it will slowly deteriorate your home. One by one the world will destroy your home and creations. The day after people suddenly disappear, the world will start to clean itself. Now that the forest is growing bigger because people are leaving nearby cities means the forest is returning to normal. A forestry student saw for himself, stunned, that there is 10 times more biodiversity and it's the only place left with all 9 European woodpecker species. It has been threatened to be harmed by war and hunters. Biatowieza Puszcza is a protected forest by the Soviet Union.
