Humans are an astonishing anomaly. As many species teeter on extinction, our populations grow in size and complexity. From exploring space to eradicating diseases and other remarkable achievements, human curiosity has pushed the outer limits of our physical universe. Yet our ability to embrace shared values has been challenging. More than a billion people live in poverty, inequality gaps are expanding, and we face unprecedented environmental challenges that threaten our survival.Continue reading »
Of all the plastic products we use and take for granted, plastic drinking straws are among the most unnecessary. Designed to be used once and discarded, their only real purpose is to keep your mouth from touching a glass or ice. It made more sense in the days when contaminated vessels were more of an issue.Continue reading »

Two of British Columbia's most iconic species, chinook salmon and southern resident killer whales, are in trouble. The whale depends on the salmon for survival. Is it time to manage chinook fisheries with killer whales in mind?
In marine ecosystems, cause and effect is a challenge. It's almost impossible to claim with certainty that depletion of one species is caused by abundance or lack of another. The general rule is that big things eat smaller things, so any given species will eat dozens of others, even their smaller kin. The southern resident killer whales, also known as orcas, are an exception. Despite their immense intelligence, or perhaps because of it, their diet consists almost entirely of chinook salmon, with only traces of other salmon, and virtually no other fish species.
Spring flooding in Canada this year upended lives, inundated city streets and swamped houses, prompting calls for sandbags, seawalls and dikes to save communities. Ontario and Quebec's April rainfall was double the 30-year average. Thousands of homes in 130 Quebec municipalities stretching from the Ontario border to the Gaspé Peninsula flooded in May. Montreal residents raced to protect their homes and families as three dikes gave way and the city declared a state of emergency. The Ontario government had to boost its resources for an emergency flood response.Continue reading »
