Greetings,
Jelly layer in Canadian lakes expanded in recent years, study found
Caused by rapid growth of plankton which secretes the gunk as defense
The species has been thriving in past decades due to rise of industry
Factories chemicals destroy minerals in soil, causing ecological change
Experts say it could be thousands of years until the situation is reversed

Once-pristine lakes in Ontario, Canada, are now coated by a jello-like layer of slime caused by decades of industrial activity, a new study reveals.
The scum coating now present on vast bodies of water in the province is due to the rapid growth of a new type of plankton which secretes the unpleasant goo, according to a team of researchers.
Years of industrial activity has eaten away at nutrients around the lakes, killing off species that used to live there and allowing the Holopedium gibberum plankton to thrive.
‘Jellification’: A researcher holds up a scoop of the jello-like scum produced by a type of plankton which has multiplied rapidly thanks to industrial processes
After-effects: A decline in calcium, caused by effects like acid rain, killed off competitors and allowed the scum-producing Holopedium gibberum to expand
Researchers – who pictured themselves scooping gelatinous handfuls of the scum out of the lakes – said they found calcium levels in the earth by the lakes had plummeted in recent decades.
Chemical waste from factories – spread by weather phenomena like acid rain – can eat away at minerals usually present in soil, causing profound changes to the animals and plants that live nearby.
According to the researchers – a mixture of government scientists and academics from the universities of Cambridge and Ottawa – populations of the plankton which produce the substance has doubled since the 1980s….MORE HERE
