I oppose the rule in favor of NACs for the stated reasons below: 1) These companies will not be obligated to abide by traditional accounting rules as every other publicly traded company is required to do weakens the standard of the stock markets and implies favoritism for desired results by a regulatory agency. 2)This will discourage economic activity especially in farming or ranching which would have deleterious effects on food supply. 3)Regulations that restrict property rights degrade the quality of life in terms of security in property ownership. 4)The term unsustainable activity is a arbitrary ter.This my be altered to attain a particular goal according to current events and or new goals ,theories not accepted by the general consensus.Who decides what sustainable is might be motivated by who can profit the most.. 5)Conserved property should be reserved to the property owner not subject to NAC affiliation.
