Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
From the beginning of time on earth fresh water supply has been humanity’s main concern. Fresh water is the key to humankind’s prosperity or poverty, comfort or misery. Without fresh water there would be no life on earth. While water covers three-quarters of the earth’s surface, it cannot always be found where it is most needed, when it is needed and in the amounts that are required.
The discovery of the water 2.4 km below the Earth’s surface has since been heralded as one of great importance, given its ramifications on what we know about the origin and evolution of our planet, the nature of water and life, as well as the possibility of finding life on Mars. Investigations into the highly saline water led to a pathbreaking discovery: scientists found that chemolithotrophic microbes– bacteria that can thrive in the most extreme surroundings– had been able to survive in the subterranean liquid.
When Barbara Sherwood Lollar sent water samples to a colleague at the University of Oxford for testing, she knew this was no ordinary water. The geochemist had spent much of her career wandering around some of the deepest mines in the world, finding and extracting water that was millions of years old. She waited and waited for results that should’ve come back promptly. So she dialled up the U.K. researcher in charge of the test. “I said, ‘Hey, what’s going on with the samples?’ ” she recalls. “He said, ‘Our mass spectrometer is broken. This can’t be right.’ ” The tests pegged the mean age of the samples, extracted from a mine north of Timmins, Ont., in 2009, at 1.6 billion years old—the oldest ever found on Earth.
On the ISS, every drop of moisture, from humidity to urine, has to be filtered and reused. But the current system is very heavy, has to be replaced every 90 days, and fails to filter out certain contaminants, according to NASA. Danish company Aquaporin A/S has developed a new system that uses proteins called aquaporins. "It is essentially the mechanism that allows water to cross the cell membrane of living cells," says Peter Holme Jensen, CEO of Aquaporin A/S. In nature, these proteins allow plant roots to absorb water from soil, and let the two human kidneys together filter about 45 gallons of fluid per day. They are also very selective, preventing contaminants from passing through.
Damage to Earth’s oceans and glaciers from climate change is outpacing the ability of governments to protect them, a new report from an international scientific panel concludes. “The capacity of governance systems in polar and ocean regions to respond to climate change impacts has strengthened recently,” says the Intergovernmental Panel on Climate Change. “But this development is not sufficiently rapid or robust to adequately address the scale of increasing projected risks.”
