Natural Disasters

Beneath our feet, Canada is constantly atremble. Earthquakes shake the country about 2,500 times per year, most too small to feel. But occasionally, and without warning, the earth's crust below Canada buckles and spasms to frightening effect. More dangerous are the tsunamis that such quakes can cause. CBC Archives looks back at notable Canadian quakes, fears about "the big one" predicted for the West Coast and scientists' efforts to better understand the threat from below.

Environmental Protection

Vancouver Island's Clayoquot Sound. Manitoba's boreal forests. The Central Avalon Peninsula of Newfoundland. These picturesque locales have served as the battlegrounds over the controversy of clearcutting — the logging practice that strips a forest bare by cutting every single tree down. On one side are the environmentalists. On the other, logging companies. In the middle are native people. The fate of Canada's old-growth forests and the forestry industry as a whole rests in the balance in the 'war of the woods.'

Environmental Protection

For over three decades, David Suzuki has been Canada's foremost environmental conscience. From his experiments with fruit flies to his warnings about genetically modified food, Suzuki has made science relevant, interesting and full of wonder to his audiences. As a broadcaster for the CBC, he has issued frank warnings against industry, the economy and his fellow scientists. Passionate and outspoken, he has also won his fair share of critics. But despite, or perhaps because of this, Suzuki remains undeterred in his message.

Extreme Weather

A tornado is the stuff of nightmares. Amid heavy rain and hail, huge thunderclouds roll in and the skies turn greenish-black. And then a rope-like funnel cloud punches down, smashing everything in its path. Tornadoes can be the most violent storms on earth, and Canada averages 80 of them each year. From scientists and storm chasers obsessed with their destructive power to the victims left in a twister's wake, we look at Canada's deadliest tornadoes of the past century.

Pollution

In May 2000, bacteria seeped into Walkerton's town well. The deadly E. coli then slipped quietly through a maze of pipes and into the homes of Walkerton, Ont. Unsuspecting residents thirstily drank the polluted water and bathed in their bacteria-ridden tubs. But soon after, they began experiencing common symptoms of infection; bloody diarrhea and throbbing cramps. Seven people would eventually die and another 1286 would fall ill. The investigation which followed exposed an alarmingly unstable waterworks system made fragile by government cuts.

Blowing dust, swarms of grasshoppers, and not enough hay to feed the starving livestock. For Prairie farmers, drought can be disastrous. But it's not just the farmers who suffer — a severe drought in Western Canada can hurt the entire Canadian economy. From the devastating dustbowl years of the Great Depression to some of the more recent Prairie dry spells, CBC Archives explores the history of drought in Western Canada.

Environmental Protection

As populations grow and cities expand, the human footprint on Earth grows ever larger. The natural world inevitably pays the price: forests shrink, lakes die and species disappear. In 1970, U.S. Senator Gaylord Nelson named April 22 as a day for grassroots demonstrations for environmental protection. His idea has flourished and continues to gain momentum as countries and consumers strive to become more "green." To mark Earth Day, the CBC Digital Archives reflects on the growing awareness of our fragile world and the people who helped shape our environmental consciousness.

Endangered Species

The Labrador duck is long gone and the wild Vancouver Island marmot is struggling to bounce back, but the whooping crane, the swift fox and the bison are actually making comebacks. With more than 30 species already gone and over 400 species of plants and animals at risk, Canada is starting to get serious about protecting its endangered species. Let's hope it's not too late.

Natural Disasters

A dry forest, some hot weather, and high winds: all it takes to set off a raging fire in these conditions is a lightning strike or a careless camper. Every summer, forest fires threaten people, property and valuable timber in Canada. But we've learned to combat these fires with a combination of scientific research, new inventions and old-fashioned courage. From lookout towers to water bombers to remote sensing that predicts fire, Canada has long been a world leader in the technology of fighting forest fires.

From its humble beginnings in Vancouver, Greenpeace has grown into the world's leading environmental action watchdog. For more than 30 years Greenpeace has battled whaling, nuclear testing and sealing, all in an attempt to protect the planet. But some say their tactics, such as confronting politicians at their private residences, go too far. Are Greenpeace a bunch of misguided liberal intellectuals and publicity-prone protestors? Or are they modern day eco-heroes? You decide.

Pollution

Between 1962 and 1970, natives in two northwest Ontario communities sat down to daily meals of poison. Their staple food — fish — had record-high levels of mercury from a chemical plant up the river. Debate still rages over just how sick the mercury has made the people of Grassy Narrows and Whitedog reserves. There is no doubt, however, that the lingering pollution was a disaster for the natives and the lodge owners who had employed them as fishing guides. Their source of food and jobs destroyed, the bands endured years of alcoholism and despair, government neglect and, finally, healing.
