It’s defeatist to say that some plants and animals should be allowed to become extinct. Here are five things we can do to help save them

Recently, there has been a lot of discussion in the scientific community about whether we should allow some species to go extinct. The argument put forward is that the number of endangered species is so great, it isn’t worth the resources to attempt to save them all. But in a wealthy country like Australia – which has some of the best ecologists, conservation biologists and conservation scientists in the world – it is critical that we do far better in managing the nation’s natural resources. A loss of biodiversity is an indicator of poor environmental management. Suggesting that we should let yet more species go extinct on this continent is too defeatist and does not inform the public about what is needed to solve the country’s biodiversity issues.
The approach to allowing species extinction has been around for some time. It’s called “ecological triage”, whereby limited resources for conservation funding are targeted at the subset of species for which management success is most likely. The approach stems from the same process used in medicine to set priorities for allocating efforts to treat patients. The ecological triage approach is thought by some to be essential because it is believed that many resources are directed to species on the brink of extinction that are doomed in the long run, and too few are targeted at declining flora and fauna that are still recoverable.
