Tomorrow is "Save the Frogs" Day! Why do we need such a day? Frogs have been disappearing worldwide at unprecedented rates, and currently one-third of the world's 6,485 amphibian species are threatened with extinction. This should come as no surprise since frog populations are being assaulted from many directions at once--global warming, pollution, habitat destruction, infectious diseases, over-harvesting and invasive species being the greatest menaces. Despite this onslaught, there’s a lot you can do to reverse this disturbing trend. First let's look at why frogs are so important to the environment—and to our very survival. Read on…

Worried about prices at the pump and a shrinking oil supply? Most of us are. As we are well aware, this commodity literally fuels our economy and its deficit is enough to spark war. But look behind the oil headlines and you’ll find the story of another developing global crisis, one likely to spark future armed conflicts and threaten the very fabric of life on Earth—a shrinking freshwater supply.

While we think of global warming as something taking place high above our heads, it’s easy to forget that those heat-trapping and often chemical-laden gases affect our lungs here on the ground before they make their way up to the clouds.

How can it be that more bluefin tuna are sold than reported caught each year? On its face, this seems an impossibility. What it strongly indicates is that fishermen are being dishonest about their catches. Bluefin tuna is a critically endangered fish, but since it brings very high prices on the market, it's relentlessly hunted. The World Wildlife Fund and some other environmental groups had predicted that the fish would be extinct by now. Though it’s not yet, marine scientists are slated to reassess the health of the bluefin population in 2012. Read on...

Located high above the western tree lines, from British Columbia to New Mexico, live a small species of rabbits called the American Pika. While these diminutive critters, otherwise known as the Little Chief Hare, may be cute and cuddly, they also have a much more serious and important role. They are among the best early indicators of climate change. Pika cannot survive longer than an hour in temperatures exceeding 75 degrees Fahrenheit, and their disappearance from their typical colonies has convinced scientists that climate change is happening much faster than expected in North America.
