Here is a lesson about the importance of dealing with climate change NOW. Under our so called Green PM; Brian Mulroney, a North American agreement on acid rain was signed. Unfortunately it now seems it was too little too late. As will be the reluctant changes capitalism will make in order to offset the current climate crisis.
Scientists say they have found lakes in Canada that are losing some of the calcium dissolved in their waters, a condition they're likening to an aquatic version of osteoporosis.
The drop in calcium levels is being attributed to the effects of acid rain and logging, which together have depleted the element in the soil around lakes, reducing the amount that is in runoff and available for aquatic life.
Under previously implemented pollution-control plans, emissions of sulphur dioxide in Eastern Canada fell by 63 per cent from 1980 to 2001, according to Environment Canada figures. As a consequence, acidity in many lakes has dropped to more normal readings, but the new findings suggests that even this massive emissions cut hasn't been enough to fully mitigate the damage from acid rain. The researchers believe the sharp drop in calcium has been under way for decades, and began in some areas as early as the 1970s.
When acid rain falls on soil, it quickly leaches out the calcium, and eventually exhausts the dirt's stores of the element, leaving little available to be washed into lakes. In the initial period of acid rain deposition, this effect temporarily increases the amount of calcium entering the lakes, but once the stores of the element are depleted, levels plunge.
Logging is also a problem because trees contain calcium they draw from the soil. When trees are cut and removed, their calcium is taken from the ecosystem. The calcium in uncut forests is returned to the soil when trees fall and decay.
Mulroney's regime demonstrated environmental rhetoric but with questionable consequences and little follow-up actions.In 1988, the Mulroney government was involved in the "Changing Atmosphere Conference" in Toronto, where government, industry, academics and NGOs exclaimed the following:"Humanity is conducting an unintended, uncontrolled, globally pervasive experiment whose ultimate consequence could be second only to a global nuclear war. The Earth's atmosphere is being changed at an unprecedented rate by pollutants resulting from depositions of hazardous, toxic and atomic wastes and from wasteful fossil fuel use ... These changes represent a major threat to international security and are already having harmful consequences over many parts of the globe.... it is imperative to act now, (Climate Change in the Conference statement, Changing Atmosphere Conference in 1988).Even after this deep concern was expressed, Mulroney did not begin to act.In June 1992, Mulroney signed the Framework Convention on Climate Change Convention, ratified the Convention in December 1992, and then proceeded to ignore the obligations incurred under the Convention and to never enact the necessary legislation to ensure compliance.The Mulroney government incurred obligations, not only under the Framework Convention on Climate Change, but also under the Convention on Biological Diversity.
