catching up with the Montreal Gazette, which I have been deprived of most of this summer and have a big pile of to sift through. On July 29 there is an article called “Death of Marine Algae threatens Earth : Study.” It reports that a new study published in Nature find that the population of microscopic algae known as phytoplankton has declined globally by roughly 40 percent because of rising sea temperatures and changing ocean conditions. One of the authors of the study is quoted as saying that “phytoplankton produce half the air we breathe.” That would suggest that there is 20% less oxygen in the atmosphere. Wouldn’t we be feeling the effects of this ? This would be like being at 8000 feet instead of sea level. Wouldn’t New Yorkers, already breathing in urban air pollution,  be  gasping for breath a bit ?
