Evolutionary progress has long been associated with the extinction
of species. So why should we be concerned now, even when the number
of species at risk is substantial, such as one tenth of the
Australian flora? The reasons for concern are many stranded.
Compassion is one strand. Remember the instructions to Noah: 'And
you shall bring living creatures of every kind into the ark and
keep them alive with you'. Guilt may be another strand, that our
hunting, clearing, collecting, pollution, introduction of
competitors and other human activities may have endangered species
such as the Orange-bellied Parrot. Nostalgia for what was and
concern for what might be also play a part; species at risk include
some which are of immediate use, such as the whales, and many of
potential use, whether drug plants in the forests of the Amazon or
a wild relative of the soybean in Victoria. Aesthetic
considerations are also involved, particularly where colourful
birds or unusual flowers are threatened. We cherish diversity, as
culturally desirable, and are delighted when supposedly extinct
species such as the notornis and coelacanth - and maybe yet the
thylacine - are rediscovered. The Loch Ness monster has already
been blessed with a Latin binomial in anticipation! Diversity is
also of ecological as well as of cultural value, contributing to
the stability of ecosystems, as in the case of insects and birds
which fertilize the flowers and disperse the seeds of plants.
