Should we humans expand significant resources to try to save another species from extinct?

I don’t believe we should unless it affects our own survival.  Of course animals become extinct because of changes in the environment.  Any environmental change which is sever enough to cause the extinction of an animal species, is very likely to affect us.

If you could pick one animal now extinct to bring back which would it be?

My first choice would not be a T-Rex. 🙂

I will pick Microraptor, a small, feathered dinosaur, which could fly or glide, and is perhaps the earliest ancestor of birds.  A flying dinosaur is pretty cool to begin with and this would helps us to understand how flight  developed and likely settle the question are birds just evolved dinos.

Save the Frogs Day – April 28th.

The Save the Frogs web site is trying to make the public more aware of the world wide threat to the amphibian species we share our world with.

Of course frogs are only one of many species facing extinction.   What concerns me more is that frogs are a “bioindicator” of the environment.  If the changes to the environment are sever enough to threaten the world wide population of frogs, it is very likely to have a significant impact on our own survival. 

“Most frogs require suitable habitat in both the terrestrial and aquatic environments, and have permeable skin that can easily absorb toxic chemicals. These traits make frogs especially susceptible to environmental disturbances, and thus frogs are considered accurate indicators of environmental stress: the health of frogs is thought to be indicative of the health of the biosphere as a whole. Frogs have survived in more or less their current form for 250 million years, having survived countless ice ages, asteroid crashes, and other environmental disturbances, yet now one-third of amphibian species are on the verge of extinction. This should serve as an alarm call to humans that something is drastically wrong in the environment.”
