Note
The desperate, and seemingly inexorably worsening, state of biodiversity on Earth
is arguably not a consequence of conscious choices. That is much of the problem.
There are undoubtedly cases, and many of them, in which people made explicit
decisions to forgo the variety of life naturally present in a given area in favour of
some alternative benefi t (e.g. agricultural activity, energy production, housing).
However, by and large, the global losses of species, and the reductions in the abundances
and distributions of increasingly the majority of others, are the outcome of
outright ignorance of the impacts of anthropogenic activities, of underestimation or
misunderstanding of the impacts of those activities, and, perhaps most signifi cantly,
a host of individual decisions which whilst independently perhaps quite rational
have led to a combined pressure on biodiversity that is far from what it can sustain.
The fi eld of conservation biology has done much to highlight the status and
trends in biodiversity, but especially the need for active and explicit choices as to its
future. Frustrating as is their failure to date to be realized, the establishment of baselines
and targets for biodiversity at regional, national and global scales is the logical
framework within which decisions can properly be made as to what environmental
changes and management actions are and are not carried forward, and with what
consequences. The ‘agony of choice’ needs to be a real choice, albeit the agony may not always be avoided.
