"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."
“We have been researching the role of artificial nitrogen in algal blooms for almost 50 years now, and these latest results clearly demonstrate that ceasing nitrogen loading into lakes has little effect on the size or duration of algal blooms,” said Scott Higgins, lead author on the paper.
