If you didn’t know, June 14 is Canadian Rivers Day! To commemorate this day, here are some thoughts on the many ways water is important to your health: Your Body Water is essential to all known forms of life. In humans, water delivers oxygen and nutrients to different parts of the body, and removes toxins and waste from the body. Water also regulates body temperature through perspiration and reduces friction between joints to facilitate movement. We can survive without food for many days, but we can only survive a few days without water! Experts disagree about the exact recommended intake of water, but most put it at about 2-2.5 liters a day. It takes an average of eight to ten cups to… read more →
More species at risk news this week, as a coalition of environmental groups represented by Ecojustice is in court to force the government to protect critical habitat for the endangered Greater Sage-Grouse. The lawsuit alleges the federal Minister of Environment failed to comply with Canada’s Species at Risk Act which requires the Sage-Grouse’s critical habitat to be identified in its recovery strategy, so it can be protected. The argument that the government failed in its duty to identify critical habitat in the recovery strategy is particularly compelling given that Greater Sage-Grouse is a very well known species, with much of its critical habitat for nesting and brood-rearing already identified in independent scientific studies. Nature Canada is not one of the… read more →
The first blockbuster movie of the summer is tearing across movie theatres this month, with Hugh Jackman in the titular, adamantium claw-wielding role of superhero Wolverine. While your opinion of the movie may be mixed, it’s undeniable that the species behind the name rocks! The endangered eastern population of Wolverines is arguably one of the most misunderstood and least known of Canada’s wild animals. There are unconfirmed sightings of this elusive creature each year, although positive identification is difficult since they can resemble porcupines, fishers, or small bears in appearance. With fewer than 50 members estimated throughout Labrador and Quebec, the greatest challenge facing this species is that the population may be too low for natural recovery. The Facts: Wolverines… read more →
Legislation to protect species from becoming extinct has been in force in Canada for six years. When Canada enacted the federal Species at Risk Act (SARA) to address the mounting threats to Canada’s endangered species, it was an important day for wildlife protection in North America. So far, it has fully protected only one species: a lucky snail in Banff National Park. The Banff Springs Snail, which exists only in the Park, is the sole species to be given an action plan in the Act’s six-year history. Countless other species like the Boreal woodland caribou, Northern spotted owl and polar bear continue to disappear with no effective help from the federal government. Nature Canada and our colleagues at Ecojustice, David… read more →
Could trees replace tundra in Canada’s Arctic? Perhaps, according to a new report to be released by 35 of the world’s top forestry scientists. (see press release) While warmer temperatures from global warming will spell destruction for forests in places like the Western US, southern Europe and Australia, Canada’s treeline may expand northward. From the Globe and Mail: Warmer temperatures will be a boon to woodlands in northern countries, as will the presence of increased carbon dioxide in the air, which will act as a type of natural fertilizer for tree growth in the Arctic. Besides Baffin Island, forests will be able to spread to most of the Hudson Bay coastline; Southampton Island, perched at the top of Hudson Bay;… read more →
A pest to a farmer; a meal to an owl. Read about how birds of prey can help reduce the use of pesticides and threats to crops, water quality and wildlife!
The Carbon Disclosure Project (CDP) is a not-for-profit organisation that holds the largest database of corporate climate change information in the world. If you are so inclined, you can read analyst reports, published annually, that provide detailed analyses of how the largest companies around the globe are responding to climate change. Combining the well-known sentiment from U.S. Supreme Court Justice Louis Brandeis that sunlight is the best disinfectant, with the biz school dictum that what gets measured gets managed, the CBD believes that making information about a company’s climate change strategy available to policy makers, investors and the general public will encourage companies to reduce emissions and climate change impacts. Last month execs at the 200 largest companies (by market… read more →
Check out these images of a robin catching his meal — gulp! The pictures come from Jim Dubois, who has his own Web site, theineleganteagle.com. Jim’s title for this image series is better than anything I’d write: Eat your greens…and your browns. Look closely, you can catch one last glimpse of the grub… On to the next course… Thanks for sharing Jim.
In our latest highly unscientific (but fun!) Quick Poll we asked our online community members how they like to spend their winters. Do they grab the wax and head for the slopes, or cosy up to the fire and stay toasty indoors? Do they start building the outdoor hockey rink or start packing their bags for Florida? Turns out many of you see the winter months as a good time to wildlife watch. According to our Quick Poll results, 41% of voters chose wildlife watching as their favourite winter activity. While the next largest group – 24% – preferred staying indoors, a review of the posted comments reveal many people actually do their wildlife watching from the comfort of their… read more →
North American scientists have demonstrated that more diverse bird populations can help to buffer people against infection from West Nile virus, according to recent research highlighted in BirdLife International’s News section today. The article (available in full from PLoS ONE, here) demonstrates a link between high bird diversity and low incidence of West Nile virus in humans in eastern North America. According to the authors, these results “illustrate an important ecosystem service provided by biodiversity, further supporting the growing view that protecting biodiversity should be considered in public health and safety plans.” The study contributes to our growing understanding of the importance of preserving bird diversity – the many benefits include maintaining important ecosystem services (like buffering humans from infectious… read more →
