a sad and beautiful slideshow of some of the more memorable and eye-catching species we've lost in a single 10-year span. many, many more have been lost, but here's a peak into that blackhole...
In pictures: - a decade of lost species |

p.s some of these are "only" extinct in the wild, but we may never get them "back". the duel blow of habitat loss and a severely limited gene-pool is exceptionally hard to overcome, even with all the human help in the world (and they have but a fraction of that)...... |

adder, none have been seen alive or dead for 20 years, so they are probably truly extinct. so sad.... |

we can't say for sure that the loss of the golden toad was related to Chytrid Fungus -see the good link below from southlander, but it is a possibility.
something is actively happening to earth's amphibians, causing their extinction rates to greatly exceed what we would expect to find in nature. please visit my above (or belowe) link and explore "amphibian ark". the worldwide "amphibian death crisis" is real and "unnatural" according to all known historic models of extinction rates.
i don't want to live in a world without amphibians.....

The Extinction of the Golden Toad FINAL
Extinction is a natural process- approx. 2% to 4% of the species that have ever lived survive today. However, the extinction rate today is estimated to be between 1000 and 10,000 times higher than the natural extinction rate (Chanson, 2004) especially hard-hit by the recent wave of global extinctions- around 122 species of amphibians have gone extinct since 1980, and one-third of the remaining 6000 species are threatened with extinction (Stuart, 2004). Only 12 percent of birds and 23 percent of mammals are in the same position. This statistic is sobering enough; it is even more startling when one considers that scientists have only named about 1.75 million species of plant and animal life out of the 13-14 million species that are believed to exist (Hilton-Taylor, 2000). Pollution is not the only factor threatening wildlife- a team of researchers concluded that if climate warming proceeds unchecked, 15% to 37% of the 1103 plant and animal species they examined will disappear by 2050 ( Sreenivasan, 2004).
