Libby, the county seat of Lincoln County, is located in a valley along the Kootenai River in northwestern Montana. The Libby valley runs east and west with lesser valleys extending north and south along Pipe Creek and Libby Creek, respectively. The Libby valley has a vertical relief as high as 4,000 ft. in some areas and is subject to severe temperature inversions during many times of the year. These physical characteristics lead to the trapping of air pollutants and give Libby the distinction of having possibly the worst ventilation
of any community in Montana <2>. The population in the valley ranges between 7,000 and 8,000 individuals while the town of Libby has between 2,500 and 3,000 persons. The population of Libby has remained fairly stable over the last 30 years.
Strip mining, transportation, and processing of vermiculite ore containing asbestiform minerals was conducted in the area from 1923 until 1990 (Figure 1). A 1982 analysis of raw vermiculite ore from Libby revealed asbestos contamination in the range of 21% to 26% <3>. The vermiculite deposit in Libby is commingled with geologic formations of tremolite <3>, a naturally occurring mineral falling within a class of hydrated silicate minerals known as amphiboles <4>. Fibrous forms of tremolite, along with other silicate-based amphiboles, are commonly referred to as asbestos. While tremolite is not mined for commercial purposes, it is a common contaminant in other commercially mined minerals including chrysotile, vermiculite, and talc <5-7>. <snip>

http://www.atsdr.cdc.gov/HAC/PHA/libby/lib_p1.htmlNow I have visited Libby many times and it's a small place in the Middle of a beautiful wilderness on the surface. But underneath the green forest canopy, crystal clear streams and rivers lies some very lethal pollution. The population is suffering from a very high rate of cancer and other diseases because of it.
Also, in neighboring Idaho, there is a fight between environmentalists and industry who are polluting the lakes and rivers with high arsenic and mercury poisoning. Clear cutting the forest is accelerating the pollution because all the poisons from mining and mill operations washes into the rivers and lakes much more quickly when there is no vegetation to absorb more of.
In highly populated states like California, we have many anti-pollution laws and measures in place that keeps the place from turning into a toxic dump, which it would if the pollution industries like the oil refineries were deregulated. So blue states really cause less pollution than the red states who don't have good regulations in place.
