In the post-industrial societies, producing ideas
and services has become the main way to create jobs and economic growth instead
of producing goods. The implications of this change for the environment are
usually seen as positive. However, critics have pointed out that despite of the
reduced pollution and resource use caused by fewer factories, also
post-industrial societies continue to struggle with resource scarcity and
environmental degradation, and in many cases consumption of natural resources
is not at a sustainable level. Still, some species and parts of the environment
can benefit from the ongoing change in the societal production structure.
Baltic salmon, endangered due to damming and pollution of rivers during the 20th
century, seems to be among those species.
