Target: Dr Gordon de Brouwer, Secretary of the Department of the Environment of Australia
Goal: Protect the remaining Australian dingo population
A recent article published by an international group of scientists has shown that predators have a crucial role in stabilizing ecosystems. These scientists warn that the excessive hunting of predators has created an environmental threat greater than climate change.
The research, published in the academic journal Science, shows that where major predators like grey wolves, pumas, and lions are absent, some species’ populations grow excessively and others shrink dangerously. Any particular ecosystem is a balancing act of predators, prey and vegetation. When the predators disappear, the prey’s numbers begin to balloon. The prey species, like deer, will then strain the existing resources of the ecosystem and ultimately decrease the health of their population by overfeeding.
In the case of Australia’s at-risk dingo population, the effects of their absence are remarkable. In areas where dingoes were in decline, fox and kangaroo species were rising. As a result, the dusky hopping mouse, other small mammal populations, and grasses are in decline.
If left unchecked, the lack of dingoes could lead to the extinction of small mammals and overgrazing or desertification. As a result, the global carbon sink would take a hit from the loss of grasses, and carbon would be released into the atmosphere. Finally, the foxes and kangaroos themselves would begin to die out from lack of sustenance.
Sign this petition to tell Australia’s Environment Secretary to institute efforts to avoid killing dingoes and to explore further protections for the carnivores.
Dear Dr. Gordon de Brouwer,
A recent article in the journal Science shows that a declining dingo population is harming Australia’s ecosystem. As more and more dingoes are killed for sport or out of necessity, the populations of foxes and kangaroos are rising, resulting in an expanding ecological imbalance. As fox and kangaroo numbers increase and feed, small field mammals and natural grasses become at risk of being wiped out. This could mean extinction of many species and desertification of many parts of Australia.
This threat can be combated by protecting the remaining dingo population. I urge you to use your department’s resources to institute better coexistence with the carnivore species. Encourage use of guard dogs instead of shotguns and explore better ways to protect the dingo species from further decline.
