THE EMPTY SEA - ILARIA PERISSI UGO BARDI KARTON...

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.
