By Alan Weisman (2007)
This is an interesting read, though there are areas I don’t really understand the terms and words used by the author. You can really learn a lot of things from this book.
There are many underground cities – one of which is Derinkuyu, discovered in 1965. It is a multi-level underground city located in Turkey. One conquring culture after another realized the benefits of such underground cities, and as it passed from hand to hand and civilization to civilization, such underground cities get deeper and deeper.
Weisman also talk about plastic pollution in his book. By 1960,s there were increasing kinds of plastic particles in the ocean. By 1990s, the samples were flecked with triple the amount of acrylic, polyster and other synthetic polymers. Not only were the amount of plastic in the ocean increasing, but even smaller bits of it were appearing – small enough to ride global sea currents.
University of Plymouth marine biologist Richard Thompson reasoned that if larger plastic pieces were breaking down into smaller particles, smaller organisms would likely be consuming such small plastic particles. Soon, everything alive, even zooplankton would be swallowing them.
Basically, the book is saying that without humans, eventually nature will reclaim the land back. Some of the experts say no virus could ever get all 6 billion human population. A 99.99% would die off, but it would still left 650,000 naturally immune survivors. Epidemics actually strengthen a species.
