| Guangzhou at max 1.5m rise of sea levels (Cassidy, The CITYFix) |
In 5000 years from
now, I think that a major coastal city like Guangzhou, China, or any other
major coastal town in the world for that matter, will no longer be inhabitable,
at least not as is conceived today. Indeed, there must have been a gradual
shrinkage of the human population for Planet Earth to survive and our civilization
to persist. A large section of humans, animals, and vegetation would have faced
a degree of biological extinction. We will be recovering from a major
biodiversity loss. Sea levels would have risen from 3 to 4 meters as one of the
potential long-term effects of global warming.
The surviving inhabitants
of Guangzhou would have harnessed major technological breakthroughs in critical
sectors, such as energy and fundamental understanding of the nature of the
universe. This knowledge will allow them to live precariously on a few sections
of their city by, for example, farming the ocean and sees.
However, some others
will be living intermittently on other planets as well. Indeed, thanks to their newly
acquired knowledge, Mars and Venus will be terraformed for the convenience of
migration from Earth. Simultaneously, they will be in the process of attempting
to “repair” an unrecognizable Guangzhou, whose climate oscillates now between cool
and too hot for human life. For example, they would try to change old transport
systems or enhance the type of settlements known in this major city today.
