Your city or town probably either has a large, brand-new hydropower dam or you know of an old one, located on the outskirts; a crumbling relic from an earlier period in your state’s history. I know this because according to the national nonprofit conservation organization American Rivers, on average our country has constructed one dam every day since the signing of the Declaration of Independence. And the U.S. Army Corps of Engineers counts approximately 75,000 dams that are greater than six feet along the waterways of the United States. In addition, there are at least tens of thousands of smaller dams spanning our rivers and streams.
Whichever version of the structure is in your area, it seems that dams divide us. While some regard them as a clean energy source, others view them as a danger to river otters and fish populations.
So, are our dams good for the environment, or a threat to wildlife?
To support what’s being billed as the “largest environmental event in history,” all you have to do is turn off your lights for one hour on Saturday, March 31, at 8:30 p.m., your local time. That’s it. It’s probably the easiest thing you’ve ever been asked to do for the planet and the natural world.
The request is a simple one because the World Wildlife Fund, the organizer of Earth Hour, is counting on millions of other people to do the same thing in a cascade around the globe, from New Zealand to Hawaii. And by using the power of our digital interconnectedness throughout the world, it’s hoped we’ll make a bigger statement — via social media — to those in positions of power about our concern regarding the Earth’s changing climate and the effect it’s having, especially on wildlife such as polar bears, tigers and sea turtles.
But in the end, will Earth Hour — and the 60 minutes you spend in the dark — really make a difference?
Was “go green” one of your New Year’s resolutions? Even if your composter is still empty and there are chemical cleaners still lurking in your cabinets, don’t fret — Only 12 percent of those who make New Year’s resolutions actually keep them for a year. Which, frankly, is 12 percent more than I would have guessed. But if you’re like me and the other 88 percent, what can help us keep resolutions is the support of others.
With that in mind, this Earth Day I’m enlisting my family in the greening goals I set for 2011. And by “greening” (aren’t we all just getting sick to death of that word?), I mean treading more lightly on my wallet, my Daytimer, my blood pressure and Mother Earth. Surely THAT’s a resolution worth fighting for!
About four years ago, the U.S. Geological Survey released a projection report stating that two-thirds of the world’s polar bears would be gone by 2050. Their numbers would plummet, stated the report, due to shrinking summer sea ice caused by greenhouse gases. Since that time, images of polar bears have graced water bottles, T-shirts and tote bags. It’s now widely accepted that Ursus maritimus is the poster child for climate change.
We also know of other species in great peril — mostly because of media attention to them. According to the Chinese zodiac, 2010 was the Year of the Tiger, and last November the International Tiger Forum was held in St. Petersburg in the Russian Federation. As the world’s first global summit focused on saving a single species from extinction, the event received widespread news coverage.
Because their likenesses appear on TV screens and spearhead conservation campaigns, chances are that even if you don’t live in tiger or polar bear habitats — where it would at least be possible for you to run into them during your daily life — you would miss them if they disappeared from our planet. But will you mourn the extinction of other species living today if you’ve never heard of them?
If it’s late morning or mid-afternoon where you are, chances are that you’ve already had at least one fleeting thought about dinner tonight. You may be picturing a juicy steak, a tender pork roast or a golden, baked chicken. I doubt that many of you dream about a steaming plate of stink beetles, leeches or cave spiders.
I spent part of the holidays in Los Angeles this year, surrounded by a sea of asphalt and traffic sprawling for hundreds of square miles. Shuttling between relatives and friends on the maze of 14-lane freeways, I soon felt spiritually exhausted by the visual din of billboards, power lines, parking lots, storefronts, neon signs and cars blowing past at 80 mph.
“Over the river and through the woods …”
Chances are, you’ll be traveling this holiday season, whether it’s a road trip to Grandma’s house or a cross-country flight to join relatives around the table for a seasonal feast. Though we all know that travel contributes to a warming climate, none of us is likely to call off the family gathering as a means of reducing C02 emissions.
Buying a kayak qualifies as a “big purchase” for my family, and my husband and I recently took that huge step. Although we’ve had a canoe for a long time, this is our first acquisition of this type of silent-sports, aquatic craft.
An island of ice more than four times the size of Manhattan broke off from a glacier in Greenland during the first week of August 2010. It’s drifting across the Arctic Ocean as you read this, probably headed to Canada’s east coast.
The white lemuroid possum may soon hold a brand-new world title: First species to go extinct due to climate change.
In December 2009, scientists reported that the possum is missing from its only home in the mountain forests of northern Queensland, Australia. It hasn’t been seen there in three years. A slight temperature rise (of only 1 or 2 degrees) is likely the reason: The possum typically dies in as few as four or five hours at 86 degrees Fahrenheit.
