EPA instructed to reverse protections for Bristol Bay salmon...
In complete disregard of previous cost:benefit analysis studies that indicated that the sport and commercial value of the Bristol Bay salmon fishery far exceeded the total gold deposit estimated value over the mine's life, opposition due to water quality degredation by indigenous peoples communities downstream of the proposed site, as well as investor pushback during Rio Tinto's ownership:

That was very interesting, Rick. Thanks for putting it up so I could read it. That, sir, is just the tip of the iceberg and maybe some day there might be a few more souls on this globe that will give more credence to what scientists have to say. So much has happened in the past couple of years.

The Administration's follow-up action was to move to reduce protections afforded to threatened species populations and make management determinations on a case-by-case basis; clear-cut, burn, and pave...

Best theory on ecosystem is.. It's like a Jenga game, you can pull out a block here and there but at some point the whole system will collapse.

Ken, you're right. An "old saw" within the community ecology field is that: the more diverse the ecosystem remains the more stable it is and the better it resists "external perturbations." As one-by-one local ecosystem support systems are removed or badly damaged, a tipping point is eventually reached. Example: Both alewife and sea lamprey had physical access to the St. Lawrence and Lake Ontario. They had limited impacts on the ecosystem because their numbers remained low until settlement and deforestation raised stream temperatures to ranges that enabled successful spawning and consequent spread throughout the watershed as well as access to the upper Great Lakes via the Welland Canal.

Darwinian evolutionary theory advanced the concept of natural selection functioning as a near constant through time. This gave rise to the creationist's counter argument that there is nearly no "gradualism" in evidence within the fossil record, therefore Darwinian Evolutionary Theory is a hoax. Steven J. Gould advanced the concept of Punctuated Equilibrium, where marked environmental change acts as the principal selection pressure on ecosystems and organisms, with speciation advancing rapidly when the local environment undergoes radical changes due primarily to geologic upheaval or a larger landscape-wide extinction event like the asteroid collision in the Yucatan Peninsula, evidenced by the Kt horizon within the strata. Now, that radical "reshaper" of the global landscape is Man.
