"Costly efforts to reduce toxic algae blooms on Lake Winnipeg by controlling the amount of nitrogen flowing into the water could have little to no impact, according to the results of a decades-long study. Scientists working in the Experimental Lakes Area in northwestern Ontario conducted a whole-ecosystem experiment on one lake, beginning in 1969."
"During the same period, carbon-emitter fossil fuels such as coal, oil and gas remained the largest beneficiaries. While subsidies to renewable energy increased by over Rs 6,700 crore ($1.05 billion), they accounted for less than 10 percent of the energy subsidies of the central government, according to this report by the International Institute of Sustainable Development (IISD), a think-tank, Overseas Development Institute (ODI), a think-tank and ICF India, a consultancy."
"Although some lakes can also absorb CO2 at their surfaces similar to the way oceans do, the increases in these other sources of organic and inorganic carbon are likely the dominant factor, says Scott Higgins, a research scientist at the International Institute for Sustainable Development’s Experimental Lakes Area, a natural laboratory of 58 small lakes in Ontario."
"In April of 2017, the International Institute for Sustainable Development released a report (whose methodology was endorsed by the Conference Board of Canada) providing an estimate of the costs of pollution on ordinary citizens and families. Their conclusion is shocking, although not altogether unexpected: pollution costs Canadian families, businesses and governments up to tens of billions of dollars annually at least!"
"Coal miners, steel, oil and gas, and construction workers are also looking at a tenuous future. The Canada-based International Institute for Sustainable Development predicts that autonomous long-distance-haul trains, automated drilling and tunnel-boring systems, and other technological job-slayers will reach their peak rates of deployment in the next ten to 15 years and replace 40–80 per cent of mine workers."
