Travelling by train north from Sydney takes you along the lovely
Hawkesbury River. It is a train trip I make frequently and as we roll
past the oyster farming structures that poke out of the water at low
tide I wonder about the future of humanity.
Ten years ago 28 oyster
farmers farmed Sydney Rock Oysters in these waters but they were
destroyed by
QX disease
in 2004. Eight farmers started again farming pacific oysters. The
number grew and grew and by last year there were 15 oyster businesses
operating in the area and there were always boats out among the wooden
stakes harvesting oysters. Earlier this year Pacific Oyster Mortality
Syndrome wiped the oysters out and now the boats are gone.
The Hawkesbury
oyster industry is one example of many that illustrates what happens
when we create imbalances in nature. Are we capable of learning the
lessons nature is trying to teach us?
