درباره این کتاب:
"The “Blue
Economy” is used to describe all of the
economic activities related to the sea,
with a special emphasis on sustainability.
Traditional activities such as fisheries,
but also undersea mining, tourism, and
scientific research are included, as well
as the phenomenal growth of aquaculture
during the past decade. All of these
activities, and the irresistible prospect
of another new frontier, has led to
enthusiastic and, most likely,
overenthusiastic assessments of the
possibilities to exploit the sea to feed
the world, provide low-cost energy, become
a new source of minerals, and other future
miracles. This book makes sense of these
trends and of the future of the blue
economy by following our remote ancestors
who gradually discovered the sea and its
resources, describing the so-called
fisherman’s curse – or why fishermen have
always been poor, explaining why humans
tend to destroy the resources on which we
depend, and assessing the realistic
expectations for extracting resources from
the sea. Although the sea is not so badly
overexploited as the land, our demands on
ecosystem services are already above the
oceans’ sustainability limits. Some new
ideas, including “fishing down” for
untapped resources such as plankton, could
lead to the collapse of the entire marine
ecosystem.
How Neanderthals crossed the sea in
canoes, how it was possible for five men
on a small boat to kill a giant whale,
what kind of oil the virgins of the Gospel
put into their lamps, how a professor of
mathematics, Vito Volterra, discovered the
“equations of fishing,” why it has become
so easy to be stung by a jellyfish while
swimming in the sea, and how to play “Moby
Dick,” a simple board game that simulates
the overexploitation of natural resources
are just some of the questions that you
will be able to answer after reading this
engaging and insightful book about the
rapidly expanding relationship between
humanity and the sea. .
