"Stop everything" does not always help

A PROTECTED rainforest in one of the world's richest biodiversity regions has suffered an alarming collapse in amphibians and reptiles, suggesting such havens may fail to slow the creatures' slide towards global extinction. Conservationists working in a lowland forest reserve at La Selva in Costa Rica compared records from 1970 to show that species of frogs, toads, lizards, snakes and salamanders had plummeted on average 75 per cent in the past 35 years.

Dramatic falls in amphibian and reptile numbers elsewhere in the world have been blamed on habitat destruction and the fungal disease chytridiomycosis. But scientists hoped many species would thrive in dedicated reserves, where building, land clearance and agricultural chemicals are banned.

The findings suggest an unknown ecological effect is behind at least some of the losses and have prompted calls for urgent studies in other protected forest areas. The researchers, led by Maureen Donelly at Florida International University, believe climate change has brought warmer, wetter weather to the refuge, with the knock-on effect of reducing the amount of leaf litter on the forest floor. Nearly all of the species rely on leaf litter to some extent, either using it for shelter, or feeding on insects that eat the leaves.

The study, published in Proceedings of the National Academy of Sciences, revealed sharp declines among two species of salamander, whose numbers fell on average 14.52 per cent a year between 1970 and 2005. Frog species fell too, with numbers of the mimicking rain frog falling 13.49 per cent and the common tink frog 6.69 per cent.

Do we need some more of these?

A fossil tree with its roots and leaves still attached has provided a tantalising glimpse of what the Earth's first forests looked like long before dinosaurs roamed the Earth. Wattieza trees covered vast swaths 385 million years ago, before even amphibians managed to clamber on to land, and had such an impact that they helped to change the planet's atmosphere.

They were the monsters of their age and are thought not only to have changed the face of the planet but also to have altered even the chemical composition of the atmosphere. The plant, which grew to at least 26 feet (8m) in height and probably to more than 40 feet, looked similar to a tree fern with a long, bare trunk that was crowned at the top with branches and leaves. Millions of the Wattieza trees would have covered the ground in coastal and other lowland regions of the planet 140 million years before the first dinosaurs.

They lived in an era when the carbon dioxide content of the atmosphere was much higher than it is today, but would have absorbed it in huge quantities as they grew. By extracting the carbon dioxide, they helped to reduce the gas to levels similar to those today. By doing so they signed their own extinction warrants because they had made it possible for broad-leafed plants to evolve 20 million years later and take over.

Greenie dictatorship resisted

Most Americans believe that dramatic steps are needed to conserve energy and reduce the threat of global warming, but they are willing to go only so far in changing their lifestyles to "go green." A USA TODAY/Gallup Poll finds that more Americans than ever - 60%, up from 48% a decade ago - believe that global warming has begun to affect the climate. A slightly larger percentage think it will cause major or extreme changes in climate and weather during the next 50 years.

And in a reflection of the impact the environmental movement has had on Americans' attitudes in the nearly four decades since the first Earth Day celebration, most people now believe that they should take more steps as individuals - such as riding mass transit and making their homes more energy efficient - to help reduce carbon dioxide and other greenhouse gases that trap heat in the atmosphere.

Even so, most people are wary of any government effort to protect the environment by imposing restrictions on how they live, work or get around. A majority of those surveyed in the poll, conducted March 23-25, said they wouldn't want a surcharge added to their utility bill if their homes exceeded certain energy-use levels. And most Americans would oppose any laws requiring cars sold in the USA to dramatically improve their gas mileage or restrictions on development to try to limit suburban sprawl.

Taken together, the poll responses indicate that Americans are going green on their own terms, depending on their interests and their wallets. The survey comes as a barrage of warnings about global warming - most recently in March, from a United Nations science panel - has transformed the climate-change debate. Going green has moved past politics to become a fashion statement, and big business. It's a shift reflected not just in the Academy Award for An Inconvenient Truth, the film on former vice president Al Gore's global-warming lecture. It's also evident in magazines from Vanity Fair to Fortune, whose recent "green" issues included hints about how to get green - or invest in companies that are.

America's move toward going green also can be seen in the ad campaigns and store aisles of the nation's largest retailers. Wal-Mart, the world's largest buyer of organic cotton, aims this year to sell 100 million compact fluorescent bulbs, which last longer and use far less energy than regular bulbs. The fluorescent bulbs typically cost five to seven times more.

In the USA TODAY poll, Americans showed a willingness to spend more money to help the environment. More than two-thirds of those responding said they should use only fluorescent bulbs in their homes. And 62% said they should buy a gas-saving hybrid car such as the popular Toyota Prius. Gas-electric hybrids typically cost thousands of dollars more than cars with gas-only engines, and buyers usually have to keep the cars for several years to break even financially.

Meanwhile, more than eight in 10 said a company's environmental record should be an important factor in deciding whether to buy its products. And 78% thought spending several thousand dollars to make their homes more energy-efficient is a good idea. But like Ari Adler of East Lansing, Mich., most Americans get more uncomfortable with the idea of going green if it were to mean limiting choices in daily life. Adler says his 2003 Jeep Wrangler "has the aerodynamics of a brick, but I enjoy the vehicle I have." As his old light bulbs burn out, "I'll replace them with fluorescents. But I'll resist the idea that we should be required to do that." Adler, 39, who works in public relations, says he is "one of those people (who) tries to do the right thing for the environment and knows there is more I should be doing, but don't necessarily do."

Indeed, only about half of those polled thought they do a good job personally of protecting the environment. Less than 10% rate their efforts as "excellent." Andy McDonald of South Bend, Ind., says he used to recycle his household trash - until the city made it mandatory and doubled his garbage bill to pay for it. "I was doing it anyway," McDonald says. "They were trying to force me to do it. I don't like that." McDonald, 29, who services motor-home diesel engines, says he often sees contradictions in his customers' commitment to going green. "In the shop, people drive in with $500,000, $600,000, $700,000 motor homes with 500-horsepower engines that get, at best, 6 mpg on the highway," he says. "And yet they tow a hybrid around to drive when they get there. It's better than driving a regular vehicle, but maybe not driving the motor home could be a greater impact."

Products that help people use less energy - or leave a smaller "environmental footprint," as green advocates say - often are more costly than their alternatives, causing some to argue that going green is only for those who can afford it. Those in older homes have to pay several thousands of dollars to replace windows with energy-saving, double-paned glass. Organic food, grown without chemicals potentially harmful to land, water, wildlife and people, costs more. So do hybrid vehicles and electricity generated by wind turbines or solar panels.

In a CBS News/New York Times poll last year, fewer than half of the respondents said they had bought a costlier, "eco-friendly" product during the past year. "The fact is, most of these products sold as 'green' cost more than the alternative," says Myron Ebell of the Competitive Enterprise Institute, a Washington think tank that dismisses climate-change warnings as scare tactics not based on sound science. "You're already pricing people at the lower end out." He cites a study by an automotive research group, CNW Marketing Research in Bandon, Ore., that calculated total energy use for several car models. Ebell says the overall energy outlay for the Prius - from design to the junkyard - is costlier "than for an SUV like my Chevy TrailBlazer. It takes a huge amount of energy just to fabricate those batteries.".....

Some analysts say the green movement is overhyped. "Despite how ubiquitous this whole green message is, a lot of people still don't know what the hell this is about," says energy marketing consultant Suzanne Shelton of Knoxville, Tenn. A survey by her firm last year found 58% of Americans could not identify a source of "green, renewable or sustainable energy," such as solar or wind. Shelton adds that 10% to 20% of those questioned say they participate in "green power" programs to pay a little extra for electricity generated by wind turbines or solar arrays. She says data from power companies show that no more than 4% actually participate. "Their answers aren't consistent with reality," Shelton says. She says she isn't certain if the responses stem from social pressure to say the right thing or if "they're misunderstanding the terminology."

The USA TODAY/Gallup Poll shows wide differences over what the government should do about global warming. About two-thirds favor spending many billions more on research into new sources of energy. But just one-third are comfortable with land-use restrictions to curb suburban sprawl, which necessitates more car trips. Only about a third favor imposing tough restrictions on U.S. industries and utilities.

For some, going green isn't about the environment as much as saving on home energy bills. Austin stockbroker Andrew Ma replaced more than 130 light bulbs with compact fluorescents in his 5,800-square-foot house after "doing the math." "It makes a lot of sense," says Ma, 34. But he says he won't give up his "gas hogs" - a Yukon Denali SUV and a Mercedes-Benz SL600 convertible - "that carry us in style and comfort." "I'm not going to get a Prius. The fun factor is not there yet," he adds. "I do treasure the environment. But I'm not one of the tree huggers."

Most mass transit riders in 50 years: Good news or bad?

A few weeks ago I noticed a startling story in the "Money" section of USA TODAY. The main head announced purportedly good news: RIDERS CROWD PUBLIC TRANSIT SYSTEMS, and then came that surprising subhead: HIGHEST USE SINCE THE 1950's AT MORE THAN 10 BILLION TRIPS. Sure enough, the body of the article explained that the American Public Transportation Association reported that ridership rose in 2006 some 2.9%, to reach the highest levels since 1957.

Did you know that there were more people using mass transit during the `40's and early `50's than there are today? I most certainly did not. This is an astonishing revelation when you think about it. First of all, the population of the country was barely half what it is today-and yet more people rode mass transit.

Moreover, during the last 50 years we've poured literally hundreds of billions of dollars into the most expensive, glitzy, ambitious mass transit projects in history--- BART in San Francisco, MARTA in Atlanta, MetroRail in LA, plus impressive new projects in Minneapolis, Portland and Washington DC, and nearly everywhere else. With all these elaborate new systems, with high-tech buses, with propaganda about global warming and government policies designed to force you out of your car, it's astonishing to think that more people used mass transit when America had half the people it has today - and none of the high-tech, new rapid transit systems.

No, we didn't use buses and subways more frequently in the long-ago `50's because the service was better: by most measures, it wasn't as good, the buses weren't as comfortable, and some of the huge systems we enjoy today didn't even exist. There was only one reason that more people used buses and trains in those days ---and that was because they were relatively poor, and couldn't afford to own or operate their own cars. As recently as 1960, Americans owned less than 400 cars per one thousand population: many families had no cars at all, and owning more than one car per household represented a privileged rarity. Today, we possess more than 800 cars per 1000 population - approaching one car for every man, woman and child, with two or three vehicles in a typical family.

Of course, many social planners and environmentalists want us give up all those gas guzzlers and get back on the bus like we did fifty years ago. But the change in automobile ownership still gives some indication of the vast distance traveled by ordinary Americans in their journey toward wealth, choices, and personal freedom. Despite the endless whining to the effect that "we've never had it so bad," the number of citizens who own their own homes has soared from barely 50% in 1950 to 70% today, and the typical home itself is more than 50% larger than fifty years ago. In 1950, 24% of homes didn't have flush toilets, and less than 2% had air conditioning. Today, virtually 100% of the places we live enjoy flush toilets (what a relief) and more than 80% of homes boast air conditioning.

It would be easy to continue in this vein, but you surely get the idea: in terms of options, conveniences, comforts, material blessings, opportunities, no generation in the history of the world has lived as lavishly as this generation of Americans.

I recently spent a weekend in Louisville, Kentucky and ended up staying in the same Hyatt hotel as literally hundreds of competitors in a National Indoor Archery Championship. Normal middle class Americans traveled from every corner of the map, carrying their high tech bows in formidable cases - as if they were toting cellos or French horns. Somehow, these ordinary salt-of-the-earth folk could travel to Louisville, stay in a gorgeous hotel, and pursue a sport that they loved with amazingly complicated and ingenious rigs for putting arrows into targets.

I've also recently visited both Las Vegas and Disneyland - neither vacation attraction limited to the rich or the near-rich. Millions of Main Street Americans can save up their money and choose their destinations - enjoying the kind of comfort and elegance and adventure that our grandparents or even our parents could scarcely imagine.

When I grew up, we never stayed in hotels - partially because with four boys my late, long-suffering mother understood her kids might wreck any facility. When we went on vacation together, we invariably went camping - because that was cheap, virtually free. I've spoken to many products of similar families from the 1950's and `60's, where hard-working parents with the Depression mentality couldn't consider wasting money on restaurants of expensive getaways.

There are many other measures of greatness, of course, beyond material well-being --- and the generations that beat Hitler and later Communism certainly deserve gratitude for the achievements, even though they lived far less comfortable, far more circumscribed lives.

Think about the cruise ship industry: hundreds of thousands of Americans can get away in every season of the year and enjoy the sort of treatment, complete with lavish meals and entertainment, which only royalty enjoyed in the past. For a shockingly low price, retirees and young couples and everything in between can pick up an amazing Alaska cruise in downtown Seattle and sail among glaciers and pods of whales. Middle class families that couldn't afford to drive cars to work some fifty years ago, now can afford to ride gleaming luxury liners on vacation.

For many of us, it's worth the effort to try to defend these astonishing, unprecedented opportunities. It isn't necessarily good news that so-called "environmentalists" and various governmental planners have succeeded in driving more Americans onto mass transit than any time in the last fifty years. Giving up your car and getting on the bus may win commendation from Al Gore, but it does represent a lowered standard of living: sacrificing the independence of taking your own wheels to work. Fifty years ago, mom and dad or grandpa and grandma understand that a country that enabled more people to drive their own cars was a country with a rising living standard; today, as liberals try to push people out of those cars, they ought to be honest enough to acknowledge that they're talking about lowering living standards.

The left argues that the threat of global climate change requires precisely such diminished levels of comfort and opportunity, but when people comes to understand these long-term goals they'll hardly see the reduced array of choices for ordinary Americans as a development that's actually worth celebrating.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is generally to promote themselves as wiser and better than everyone else, truth regardless.

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists
