If only there were a rewind button.

From the first, almost cheerfully do-able estimate of 1,000 barrels of oil spewing daily into the Gulf of Mexico to a…

• jaw-dropping 5,000 barrel revision

• horrifying 19,000 barrel update

• are-you-kidding-me? 25,000 barrel recalculation

• and an it’s way-way-way-more-than-the-Exxon-Valdez admission

…the bad news on the BP catastrophe has gone so far off the dial, it has zoomed past “worst case scenario” to “pretty much the worst case ever.”

Dispersants that present environmental issues of their own have only made the situation more complex. “We’re dealing with an aggregation of hundreds of thousands of patches of oil,” according to Admiral Thad W. Allen, the Coast Guard commander in charge of the clean-up. It will takes months to scrub the surface. Years at least to scrub the wetlands.

Dark hair, dark eyes, black jeans, scarf just so, slightly dissatisfied expression and a brisk pace that makes it look like you know where you’re going: Expect to be asked for directions early and often on the streets of Rome.

As long as I kept the dialog to “buon giorno,” “uno” (when pointing to a particularly remarkable pastry), “grazie” (when buying said pastry) and “sera” (turns out “buona” is optional), the illusion was perfect. I was Roman. So what if I had only the sketchiest of mental maps of the city and came across the Trevi Fountain by chance? Or that my  concrete-coddled American legs were no match for the Eternal City’s infernal paving stones? I was Roman enough to have paid my respects at Julius Caesar’s surprisingly humble tomb at the Forum:

Still, two or three times a day, someone would burst my bubble with a babble of Italian, forcing me to admit that I was but a clueless American, likely more lost than they. That was until I met the undaunted Eva, who replied that she was Dutch and spoke English. She  asked one of the few questions for which I actually had an answer: “Do you know the way to the Piazza Navona?” “Si, si! Just heading that way myself…”

Five years ago, in a move as practical as it was visionary, the Hôpital Albert Schweitzer (HAS) in Haiti began planting trees – lots of trees – in an effort to mend an ailing landscape.

Small farm plots on hilly terrain had been stripped bare of soil-stabilizing cover (2/3 of the the country is on land that slopes 20% or more). No soil means no food means malnutrition means disease, illness, death.

“Practically every medical problem in Haiti is poverty-related,” notes Dr. Vehnita Suresh, the hospital’s CEO. “The never-ending cycle of deforestation lead(s) to more ecological damage, more compromised farming, more poverty and more hunger. It goes on and on and on.”

Public health and environmental health are so tied together, you simply can’t have the former without the latter. “We can go on giving health-care forever,” says Dr. Suresh, “It would never really touch even the brim of the problem here.”

Waiting for diplomats to resolve the global climate crisis may take so long, it won’t matter. So what do we do in the meantime?

At TrackerNews, we have highlighted all kinds of promising green energy ideas, from micro-wind andsolar textiles to vast arrays of concentrated solar collectorsand giant “sea snakes” harvesting wave energy.

We love them all and their heartening range of ingenuity and resourcefulness. But none of them – or even all of them taken together – can do much to move the global thermostat in the near term, especially without the political will and the investment that results to grow them to scale.

We began to wonder whether there were any ideas that could make a difference, that could actually help stabilize our feverish planet within a matter of years instead of decades. We found five – an encouraging start. Notably, all take their design cues from nature and offer multi-faceted benefits. Nature, notes Janine Benyus of the Biomimicry Institute, relies on technologies that have been field tested for millions of years, the ultimate in iterative design. It works. Every time.

Leave it to an 8 year-old. Specifically, the 8 year-old son of Jim Warner, managing director of design consultancy Brandimage, who took one look at a plastic bottle his dad had helped create and said, “Oh. You make trash.”

Once the sting of that nasty little unvarnished truth wore off, Warner set to work to make not just a better bottle, but a better approach to bottling altogether. And with the 360 Paper Bottle, he may have hit the eco-ball straight out of the cradle-to-cradle design park.

The swine flu genie, now officially out of the bottle as a WHO-certified global pandemic, has left a trail of mostly non-lethal misery (so far) stretching across 145-and-counting countries.

• In the U.K., experts predict there could be as many as a 100,000 cases per day by August – which would also dash hopes for an economic recovery any time soon, according to a new study.

• In Argentina, flat-footed bureaucrats are in the cross-hairs for taking too long to implement protective measures. Now Argentine pigs are sick, too.

• In Saudi Arabia, where nary a pig dares wander, officials are bracing for millions of devout Muslims planning hajj trips this November, advising the old, young, pregnant and those with chronic conditions to reschedule.

• In the U.S., a new survey suggests that obesity doubles the risk for serious flu complications. Exactly why this is so is a bit of mystery, but a mouse study may provide a clue. Fat mice produce elevated amounts of leptin, a hormone involved in immune response. Researchers theorize that the mice became desensitized to leptin, so their immune systems don’t kick into gear fast enough. When their immune systems finally do kick in, they go into overdrive with a “cytokine storm” – a defense so strong, it kills the host.

Hope Phones is one of those “Gosh, yes!” ideas:

• Get people to donate old cell phones to a recycling company
• Get recycling company to assign each phone a value
• Use value to trade for refurbished phones
• Donate refurbished phones to clinics in developing countries to use for sending health-related text messages
• Good begets good

Stanford student Josh Nesbit, who came up with the scheme, spent last summer at a tiny hospital in rural Malawi armed with 100 refurbished phones ($10 per), a used laptop and some free software called FrontlineSMS for managing text messages. Could he set up a phone network to deliver more and better health care to the 250,000 people living in the region served by the hospital?

If cars and trucks could reproduce, they would surely rank as the planet’s dominant species. From the tiniest Tata Nano to the most massive of monster mega-trucks, guesstimates for the the global fleet now approach, if not exceed, one billion. By mass and weight, humans were left in the CO2-laced dust a long time ago. Nothing in the history of history, short of an asteroid, has ever had such a speedy and profound global impact. It is a car & truck world. And we have to live with it.

Or at least try to make the best of it.

Last week, the World Health Organization ratcheted up its pandemic rating for swine flu (aka H1N1) all the way to an unprecedented “pandemic imminent” level 5, with a top-of-the-chart 6 considered inevitable. Was it time to wear masks? Stock up on Tamiflu and canned goods? Update wills? Pull out old high school lit-class copies of The Decameron?

Well, no. At least not yet. Plenty of people got sick, but is was mostly run-of-the-mill seasonal flu-style misery. Fevers, aches, pains, head-aches, gastrointestinal woes. In the jargon of the public health set: “mild.”  Yet swine flu remains an imminent pandemic and will likely be once all the cases are tallied up.

What’s wrong with this scale?

Quite a few things, it turns out. But the biggest complaint from doctors (including my neighbor, a hospital administrator at a major medical center in Chicago) has been its emphasis on viral spread rather than  severity of illness.

If a picture is worth 1,000 words, then surely a GigaPan is worth a million. For a little over a year, a team at Carnegie Mellon University has been promoting a camera robot — originally developed by NASA to snoop around Mars — for home-planet use. The unit, which can be used with almost any digital camera, costs just under $300, but the “stitching” software that creates the signature zoom & pan panoramas, is free. Also, unlike Microsoft’s Photosynth, it is compatible with both Mac and Windows. (National Geographic partnered with Microsoft Live Labs to create Photosynth images of global landmarks, which, unfortunately, cannot be viewed from my MacBook.)

The images are stunningly addictive. Like Peter Parker-turned-Spiderman, you’ll find yourself able see farther, deeper and with more clarity than you’d ever imagined. Surprisingly, it doesn’t take long to get past the realization that privacy as we knew it is gone. With police cameras at every intersection, surveillance cameras everywhere else (including the new 5-eyed wonder from Scallop Imaging that takes up about as much space as a light switch) and Google Earth, perhaps we’ve known it’s been gone for while. Now, at least, we get to share the pictures.
