rabel,
Back here,
You wrote:The government sells public ground to industry for about 6 dollars an acre ...
an inaccuracy, in that The Federal Government does not sell the land, but rather grants patents pertainining to the land, which patents may be converted by the holders to resource exploitation leaseholds under the provisions of public laws enacted in 1866 and 1872 (Mining Law of 1866, 14 Stat. 251), and The General Mining Law of 1872, (17 Stat. 91 - codified at 30 U.S.C. §§ 21-54), 1920 (Mineral Leasing Act of 1920, 41 Stat. 437), and 1947 and 1955 (Surface Resources Act of 1947, 69 Stat. 367 as ammended 1955 - codified at 30 U.S.C. §§ 601-15). Suggested further reading would include 1997's
HR 253,
HR 778 and its companion,
HR 780, all of which have been languishing for the better part of a decade, but that's really neither here nor there per this discussion. What is at issue is the assertion public lands were sold, which is not the case. Recurring-payment leases permitting resource exploitation were granted, with requirement that reclamation of the land to condition once more suitable to public use upon cessation of resource exploitation be effected at leaseholder cost, and in many but not all instances further requiring royalties be paid to the public treasury based on the market value of the resources exploited.
then you wrote:This gives them the right to mineral and lumber rights on said ground.
Thats all that is granted, the right to exploit resources, and with that right goes the obligation to clean up afterward.
It should be noted too that there has been an effective moratorium on the granting of new patents and leaseholds since 1994.
