I wrote about tobacco companies and their efforts to keep their products on the market after they tried unsuccessfully to cast doubt on the science showing the disastrous effects of smoking on health. Tobacco companies, led by Phillip Morris International (PMI) are fighting to keep their deadly product in the limelight around the globe, where even small, relatively backwards countries have recognized the evils of smoking and tried to discourage the addictive and deadly habit. PMI has even pressed the U.S. Government for
language that would make it tougher for countries in a proposed
Pacific Rim trade pact to require plain packaging or other
limits on company logos. Australia’s packaging law is being
challenged at the World Trade Organization, and U.S. senators
from tobacco-growing states, including Senate Minority Leader
Mitch McConnell, recently warned the European Union that smoking
controls it’s considering could endanger a U.S. trade deal.Listen to John Oliver's amusing, but nevertheless, distressing take on this.
In the long history of evolution it has not been necessary for man to understand multi-loop nonlinear feedback systems until very recent historical times. Evolutionary processes have not given us the mental skill needed to properly interpret the dynamic behavior of the systems of which we have now become a part. J. W. Forrester, 1971

Oh Zooxanthellae, wherefore art thou?
Warmer sea surface temperatures as a result of global warming are blamed for an increase in a phenomenon called coral bleaching, which is a whitening of coral caused when the coral expels a single-celled, symbiotic alga called zooxanthellae. This alga usually lives within the tissues of the corals and, among other things, gives them its spectacular range of colors.
Zooxanthellae are expelled when the coral is under stress from environmental factors such as abnormally high water temperatures or pollution. Since the zooxanthellae help coral in nutrient production, their loss can affect coral growth and make coral more vulnerable to disease. Major bleaching events took place on the Great Barrier Reef in 1998 and 2002, causing a significant die-off of corals in some locations.
