Canada's Conservative party's plan to battle industrial pollution may be the most costly to government, the most damaging to the economy, and the least effective at cleaning the atmosphere, according to a federal government analysis of climate change policies. "This approach requires many initiatives, likely by three different orders of government, with the associated administrative costs," said the report. And, the report continued, "because it does not use market forces to find the lowest-cost emissions reduction opportunities, it is inevitably a higher-cost approach than those based on emissions trading. . . . This option likely also provides the least certainty for meeting a target." Meanwhile, a study from the University of Alberta showed that a relatively harmless form of mercury changes to a deadly neurotoxin when it enters sea water. Inorganic mercury, released from industrial activity like coal-burning power plants, undergoes a process in sea water that turns it into monomethylmercury. According to one of the study's researchers, the neurotoxin's presence in Arctic waters may have serious implications for human health, especially in Inuit groups, whose diets traditionally rely heavily on fish and marine mammals. In addition, according to the study, toxic monomethylmercury accounts for approximately 50% of mercury found in polar waters.
