Devil Facial Tumour Disease (DFTD) has a 100% fatality rate. :skull:

It has killed 90% of the species since 1996.

They have captured 500 breeding pairs to be kept in Zoos to prevent total extinction, but extinction in the wild is all but guaranteed.

Fancy that, an extinction not caused by humans...go figure :roll:

Well, the vast majority of extinctions over the last 500 years have human attributed causes, a non human cause is rare.

This is really sad. For years I've worried that at least one animal that one of my favorite cartoon characters is based on would go extinct in my lifetime (not one that already has been extinct for years like dinosaurs or even the Dodo Bird), but I always thought it would be pandas or even elephants. Back in the 90's I was always hearing about elephants being horribly killed for their tusks. :(

I wouldn't count the Tasmanian Devils out yet. A lot of times when a 'new' disease enters a virgin population, the mortality rate can be 90% or higher. Then when the survivors breed, they pass on their immunity and the death rate plummets.

It seems to me that a lot of the blaming of extinctions on humans is due to the fact that there is evidence that people were in the area at about that time. I would say you could argue that humans were a contributing factor, but I think people need to be pickier about the 'facts' they throw around.

Or use common sense, such as: humans entered the area, everything died right when they got there, obviously they did something that f****d up the ecology of the place.

I read about this last year, it is quite sad, first all the Tasmanian Tigers went extinct from humans and now this natural extinction of the Devils is upon us.

Or that particular population was on the crux and one little additional element pushed them over the edge. I work with living things, I undoubtedly know more about life processes and applied biology then most people. What I said is that we can't always know the actual causes of such events, and we shouldn't jump to conclusions. If you want to stop something from dying, you need to stand back and view the situation with a clear eye, not have a knee-jerk reaction. :roll:

A classic case of both direct and indirect human causes. Between importing better equipped predators and active hunting, no more Tasmanian Wolves.
I saw a show a few years back that talked about prehistoric predators of Australia. They put forth the theory that the introduction of the dingo by the Aborigines tens of thousands of years ago led to their extinction on the mainland but not on Tasmania. You have to wonder why, as surely they introduced dingoes into Tasmania. Complicated system, life is.

Therein lies the problem, most ecosystems are a delicate balance, any introduction of foreign species will alter an ecosystem, if said foreign species can survive the environment they will change it. Let's be honest most human caused extinctions aren't generally caused by humans going in and killing every member of a species, they're caused by humans introducing other species that unbalance the ecosystem. You can call that "indirect" if you want, or any other terminology you want to diffuse liability, but the fact remains in most cases that had humans not been involved a majority of the species going extinct in the current mass extinction event wouldn't have happened. Our callous disregard for nature and constant denial of our ability to change our environment is the core cause.

You're not making any sense. When Europeans discovered Australia there were dingoes on the mainland,and there were no dingoes in Tasmania. The most likely reason for their absence from the island is that they never made it there.So what's to "wonder" about?

Read it again, they are referring to aboriginals bringing Dingos to Australia when they migrated to Australia 40,000 years ago.

Oops that one accidentally posted, I was confused by your misuse of quotations, attributing what glebel said as what I said. Disregard it
