Dear all
Marilyn's list is OK at a childrens level but it totally fails
to say deal with complexity.
For instance, readers of BOCA's conservation newsletter (The
Harrier) will be aware that simplistic culling of top introduced
predators (eg fox) may increase the numbers of meso-predators
(eg rattus both introduced and native) with negative impacts on
birds.
More generally lack of research and thought by humans - often
prompted by greed and payoffs - is the major problem.
All Australian governments have, I believe, signed up to the
environmental sustainability/principles of environmental
protection which are listed, for instance, in Victoria's latest
Environment Protection Bill.

Of course these are not just about birds and sometimes things
that are good for particular bird species in the short term are
bad for ecosytems (eg camphor laurel, rabbits).
