Light pollution (light smog light pollution or light emissions) is a fundamental problem in
metropolises with effects on flora fauna and people. Accordingly the first section of the
book discusses the basics of light pollution and its effects on various organisms. The
characteristics of light smog in the cities of Hanover Warsaw Boston New York City and
Toronto are then analysed and compared. But how can the problem be tackled? Existing measures
for the prevention of light pollution are discussed and further novel approaches are shown by
comparing the metropolises. The book is aimed primarily at practitioners in this field and
helps to identify sources of emissions and identify suitable reduction measures.This book is a
translation of the original German edition Lichtverschmutzung in Metropolen by Emlyn Etienne
Goronczy published by Springer Fachmedien Wiesbaden GmbH in 2018. The translation was done
with the help of artificial intelligence (machine translation by the service DeepL.com). A
subsequent human revision was done primarily in terms of content so that the book will read
stylistically differently from a conventional translation. Springer Nature works continuously
to further the development of tools for the production of books and on the related technologies
to support the authors.
