There have been many well-publicized cases of invasive species of
plants and animals, often introduced unintentionally but sometimes
on purpose, causing widespread ecological havoc. Examples of such
alien invasions include pernicious weeds such as Japanese knotweed,
an introduced garden ornamental which can grow through concrete,
the water hyacinth which has choked tropical waterways, and many
introduced animals which have out-competed and displaced local
fauna. This book addresses the broader context of invasive and
exotic species, in terms of the perceived threats and environmental
concerns which surround alien species and ecological invasions. As
a result of unprecedented scales of environmental change, combined
with rapid globalisation, the mixing of cultures and diversity, and
fears over biosecurity and bioterrorism, the known impacts of
particular invasions have been catastrophic. However, as several
chapters show, reactions to some exotic species, and the
justifications for interventions in certain situations, including
biological control by introduced natural enemies, rest
uncomfortably with social reactions to ethnic cleansing and
persecution perpetrated across the globe. The role of democracy in
deciding and determining environmental policy is another emerging
issue. In an increasingly multicultural society this raises huge
questions of ethics and choice. At the same time, in order to
redress major ecological losses, the science of reintroduction of
native species has also come to the fore, and is widely accepted by
many in nature conservation. However, with questions of where and
when, and with what species or even species analogues,
reintroductions are acceptable, the topic is hotly debated. Again,
it is shown that many decisions are based on values and perceptions
rather than objective science. Including a wide range of case
studies from around the world, his book raises critical issues to
stimulate a much wider debate.
