Sad but true

September 30, 2008

Esto lo escribió Michael Begon en ECOLOGY From Individuals to Ecosystems (2006):

Much of conservation biology is a crisis discipline. Managers
are inevitably confronted with too many problems and too few
resources. Should they focus attention on the various forces that
bring species to extinction and attempt to persuade governments
to act to reduce their prevalence; or should they restrict activities
to identifying areas of high species richness where reserves can
be set up and protected; or should they identify
species at most risk of extinction and work out ways of
keeping them in existence? Ideally, we should do all these things.
However, the greatest pressure is often in the area of species preservation.
For example, the remaining populations of pandas in
China or of yellow-eyed penguins (Megadyptes antipodes) in New
Zealand has become so small that if nothing is done the species
may become extinct within a few years or decades. Responding
to the crisis requires that we devote scarce resources to identifying
some special solutions; more general approaches may have
to be put on the back-burner.
