On August 4th the tailings impoundment at the Mount Polley mine failed, releasing 25 million cubic metres of mine waste and construction material into the watersheds below. Some of the waste backed up into Polley Lake, most of it was dumped into the 10km Hazeltine Creek watershed and some spread downstream into Quesnel Lake.
Investigations into the causes and legal implications of the spill are ongoing as is monitoring of the impacts. Preliminary water sampling results show increased levels of copper and other metals in the water column where a plume of fine sediments is moving with the currents in the lake. There is also concern over an increase in the E coli bacteria in water as residents used to draw drinking water straight from the lake. There are observations of increased algae and weed growth due to the fertilizing effect of phosphorus in the wastes. Researchers from the Quesnel River Research Centre have noted that the impacts of the spill may last decades.

About one-fifth of the world’s ancient forests remain intact. The forests have protectors and champions, but Earth still loses ancient forest every year to human enterprise, and now, to the new human-mediated climate.
Half of Earth’s forests – the once great forests that stood on Earth ten thousand years ago, at the dawn of human agriculture and empire – are entirely gone. However, that measure accounts only for land area – approximately six billion hectares of forest reduced to three billion. Most of the remaining forests survive only as tree
