Stop Being a Bag Lady (or Bag Guy)

| Posted 08.01.2012 | Canada

Canadians use between nine and 15 billion plastic bags a year, enough to circle the Earth more than 55 times, according to Greener Footprints. (U.S. citizens use about 100 billion a year!) Few plastic bags are recycled. Plastic bags are bad and for the most part unnecessary. Many of us older folks remember a time, only a few decades ago, when we didn't have them. Sure, they're convenient, but is that an excuse to damage the environment and the life it supports?

Where Christy Clark Went Wrong

| Posted 08.08.2012 | Canada Politics

B.C.'s premier Christy Clark was right to walk away from a national energy strategy promoted by Alberta's Alison Redford at a provincial premiers' meeting in Halifax in late July. She just did it for the wrong reasons. Clark should have renounced the proposal because it's focused more on tar sands, pipelines, and markets than on getting Canada's greenhouse gas emissions under control.

Une application cartographique pour aider à intégrer la nature dans l'équation

En utilisant l'énergie des rayons solaires, un arbre peut absorber jusqu'à 400 litres d'eau du sol chaque jour et rafraîchit l'air ambiant par la transpiration. Les arbres absorbent les contaminants atmosphériques et expulsent de l'oxygène pur. Ils constituent des filtres à air si efficaces que les chercheurs de l'Université Columbia évaluent que, pour chaque lot de 343 arbres ajouté dans un kilomètre carré, les taux d'asthme chez les jeunes diminuent d'environ 25 pour cent.

How Destroying the Environment Destroys our Health

| Posted 08.15.2012 | Canada

According to an article in the New York Times, "emerging diseases have quadrupled in the last half-century." The increase is mainly due to human encroachment into and destruction of wildlife habitat. For example, one study concluded that a four per cent increase in Amazon deforestation led to a 50 per cent increase in malaria because mosquitoes, which transmit the disease, thrive in the cleared areas.

Climate Change Deniers Are Almost Extinct -- But Is it Too Late?

| Posted 08.22.2012 | Canada Politics

Most North Americans know that human-caused global warming is real, even if political leaders don't always reflect or act on that knowledge. According to a recent poll, only two per cent of Canadians reject the overwhelming scientific evidence that Earth is warming at alarming rates -- a figure that may seem surprising given the volume of nonsense deniers.

Water: Is the Glass Half Empty or Half Full?

| Posted 08.29.2012 | Canada

Just as human activity is upsetting Earth's carbon cycle, our actions are altering the water cycle. Water is our most precious resource, but we waste it, just as we waste other resources, including oil and gas. When we use so much that the system can't renew itself, we create shortages and drought. When we pollute it, we make matters worse.

La population en a assez de la destruction de l'environnement

| Posted 08.30.2012 | Canada Quebec

Si la prévention est la meilleure façon de diminuer les coûts en santé, pourquoi les gouvernements ne mettent-ils pas plus de moyens en œuvre pour protéger l'environnement? Nous savons depuis longtemps que les facteurs environnementaux, en particulier la contamination de l'atmosphère, de l'eau et du sol, peuvent causer des maladies. Les scientifiques réalisent maintenant que ce lien est encore plus direct que nous ne le croyions.
