On the termination of species
- ecologists' warnings of a ongoing mass extinction are being challenged by skeptics and largely ignored by politicians
- 90% of species do not yet have names, let alone censuses, they are impossible to verify.
- Eminent ecologists warn that humans are causing a mass extinction event
" If you are looking hard evidence of 10 or 100s or 1000s of species disappearing each years, you aren't going to find it " - Kirk. O Winemiller, Texas A&M. Current estimates that between 1 and 10% of species are extinguished every decade, at least 27000 per year. 30% extermination of all species. Western Australia has highest percentage of threatened species that was 17.5%, and extinct species, that was 6.6/1000. 33 of 92 freshwater fish presumed extinct by IUCN are definitely gone forever. Extinction causes:
* overfishing, hybridization
* loss of food supply
* forest destruction, overhunting
* predation by introduced brown tree snakes
* land conversion
* industrial and urban pollution
With more than 1100 species suspected to have disappeared in the past 500 years.
- Extinct species:
* deepwater ciscoe
* pupfish
* Dobson's fruit bat
* Caribbean monk seal
* Guam flycatcher
* Kaua'i'O'o
* Xerces Blue butterfly
* Tobias' Caddis Fly
We should first try to save relatively pristine and innexpensive land were evolution can progress unaffected by human activity.
So what?
- We are strongly losing our species every single day without notice. Now it's time to be active and distribute saving our species.
What if?
- All species become threatened or extinct?
