How do you celebrate one of the largest pools of freshwater on Earth? By participating in the annual Lake Superior Day, that’s how! This Sunday, July 20, is Lake Superior Day, a day of celebrations for the world’s largest and cleanest freshwater lake.

Towns and communities lining the shores of Superior in Michigan, Minnesota, and Wisconsin, and the Canadian province of Ontario are planning all sorts of events in tribute to the greatest of the Great Lakes.

Picnics, beach clean-ups, library displays, kite flying, concerts, hikes, an essay contest, and government proclamations are all part of the day’s celebration to bring attention to this huge body of water that holds 10 percent of Earth’s fresh water. Events are planned all around the lake. For example, games and activities promoting water conservation will take place in Red Rock, Ontario. A family picnic is scheduled at Silver Harbour in Thunder Bay, Canada. Afternoon events will take place on Barker’s Island Festival Park in the city of Superior, Wisconsin, and scientists and lake area experts will be on hand at the Lake Superior Maritime Visitor Center at Canal Park in Duluth with information about the lake’s natural history, regional culture, and invasive aquatic species.

The annual event takes place on the third Sunday of July, and is sponsored by the Lake Superior Binational Forum, the U.S. Environmental Protection Agency, and Environment Canada. So, if you're anywhere near Gichigami this coming Sunday, join in the festivities, or just go jump in the lake!

In my continuing quest to keep the public informed about exploding household objects, I bring you the case of the exploding......FLOWERPOT house fire?! I’m sorry but of all the things that could explode, a flowerpot falls pretty low on my list of potential hazards. The St. Paul Fire Department investigator, James Novak, agrees, “It’s not like everybody has to worry that their house is going to burn down...halogen lights, smoking, candles and Pop-Tarts in a toaster--there are a lot of things higher on the priority list than a potted plant fire.” Nevertheless, the combination of fertilizer, heat and oxygen within the pot can lead to potentially unorthodox flower pot behavior. Consider yourselves warned. As for me, I think a conversation with my fern about fire safety is long overdue.


To post, or not to post

So I'm surfing the web and I come across an item about DDT use in Africa. If it's true, then this is the kind of thing that really frosts my shorts. But, as the blogger notes, the item has only appeared in a couple of fringe outlets. Not that I consider the MSM the font of credibility. But I've already been taken to task for the Space Camp Barbie post, so it would be nice to have verification.

Anyway, according to this report, a Dutch textile firm is refusing to buy cotton from parts of Uganda which use the chemical DDT to combat malaria. Malaria kills up to 100,000 Ugandans every year. DDT effectively controls the mosquitoes that spread the disease.

But DDT has a downside -- it gets into the environment and poisons fish, birds and other wildlife. For this reason, it has been banned in the US and other Western countries for more than 30 years.

Countries that use DDT today don't spray food crops. They use small, safe amounts and generally confine its use to indoors, protecting people from malaria-ridden mosquitoes.

But this apparently is not good enough for the Dutch. According to the report, the company is refusing to buy cotton from areas that use DDT, claiming the crop is no longer "organic." As a result, farmers from those areas cannot sell their cotton at full price, and are losing money.

Basically, European eco-purists are giving African farmers a choice: avoid DDT and die of malaria, or use DDT and die of starvation. The Euro-elites, of course, face neither of these fates.

Like I said, this is based on just one report. It would be nice to get independent confirmation.

As fires continue to rage in the forests of California, I thought I would introduce you to some of the people trying to control them. Smokejumpers are the logical people to start with as they are usually the first on the ground.

Smokejumpers are the elite forces of the US forestry department. Many fires begin in locations inaccessible to the standard means of transportation (trucks, helicopters, or by foot). These firefighters arrive by plane and parachute into remote areas. Often their landing site is the top of a tree or a boulder field. Their kevlar suits provide some protection but their skill set includes tree climbing, practiced falling and general hardiness.

In the beginning, jumpers were required to be unmarried without dependents. They had to be a bit reckless to be able to agree to jump out of a plane into a fire area! Despite the inherent danger of jumping, there have been relatively few fatalities in their long history. Jumping began in the late 1930s as flight technology and airplanes became more sophisticated. During the war, many of the jumpers were conscientious objectors to WWII. In 1981 the first women were allowed into the program. Today there are 9 active bases in the West but they serve fires from Alaska to the North East.

The physical requirements... 7 pull ups, 25 push-ups, 45 sit-ups, and a 1.5 mile run completed in under 11 minutes---all done in one session with a 5 minute break between each activity. So, I am pretty much disqualified right off the bat with the pull ups and even if I were to manage, the running would definitely eliminate me. I view running as a self destructive behavior (who would put themselves through that? sorry El). You must also be mentally and emotionally stable--that is a requirement! A smokejumper’s pack often weighs upwards of 100 pounds...and you have no ride out, you must hike or hitchhike in (after landing) and out of the fire. To see a complete list of physical requirements (including height and weight) check out the West Yellowstone smokejumper website.

What they do : After landing and recovering their gear (which is dropped from the plane in (hopefully) a relatively similar location to where they land) the crew sets out towards the fire. They carry no water save for their thermoses. They control the fire by either creating a fireline/firebreak, a swath of land around the edge of the fire cleared of any brush or fuel that could feed the fire, or they light a backfire . Backfires act much like a fireline/firebreak in that they burn towards the oncoming fire. By doing so, they remove the fuel the fire needs to continue burning. Only if the jumpers are unable to contain the fire are reinforcements called to the scene. Jumpers direct helicopters to drop water on hot spots and systematically work their way through the burn site feeling the ground to make sure that there will be no flare-ups. They can leave when the fire is controlled or fresh firefighters take-over, often times many hours after they first jumped from the plane.

Be sure to check out the links below. Jumpers work from June-Oct so those of you looking for adventure with an extremely selective and tight-knit group, smokejumping could be for you.

Scientists are working to create more environmentally sensitive pyrotechnics . Their research may have far reaching applications. Many military missiles and flares share a similar chemical make-up to fireworks. By adjusting the formula, scientists hope to reduce the amount of perchlorate involved in each reaction.

The age of the crustaceans is upon us, and, like the elves before us, it is time for we chordates to fade into legend. Though some of us may linger in this fallen world, much that was good will have been lost. The air will be full of, like, clicking, and eyestalks will be all the rage, and everything will smell like ammonia.

And, oh yes, there will be tentacles. And before you get all sassy about crustaceans not having tentacles, shut your word-holes and open your listen-orifices—I ent just talking about crustaceans. In this damp, horrifying future, the crustaceans will be accompanied by their nightmare 6th cousins: the mollusks.

It’s the presence of mollusca that is most frightening to me. I can not imagine a crustacean that couldn’t be handled with a claw hammer, but mollusks…they’re something else entirely. Huge, clever brains, instant biological camouflage, boneless bodies, marine gigantism, beaks…

As ocean temperatures rise with global climate change, many marine populations are predicted to shift dramatically from fish to crabs, lobsters, and squid.

Fish populations have also been observed switching from cold water to warm water species, away from bottom feeders, and trending towards smaller species.

The whole thing, it’s thought, is primarily the result of a change in where in the ocean plankton is being consumed; small, warm-water species of fish are eating the plankton (itty bitty sea life) higher up in the water column, so less plankton settles down for bottom feeding fish. As the bottom feeders die off, invertebrates like mollusks and crustaceans move in.

Warming oceans are probably the main cause here, but researchers say that over fishing could be a contributor as well. As larger fish become less common due to fishing, there are fewer predators for small fish, which eat off the plankton high in the water table…

Prepare for the worst. Remember: claw hammers for crustacea, marshmallow skewers for mollusca, and an acceptance of inevitable death by pinchers for the rest of us.

That is the question. Controlled burning is a technique where by intentional fires are set to clear forests of debris. Fires sparked by lighting have always been a part of the life cycle of forests. Though it seems counterintuitive, fire can actually be a very healthy thing. It clears the forest floor strengthening older trees by giving them more access to soil nutrients while also acting as a kind of natural recycling. Regular burning (burning that mimics what formerly naturally occurred in forests) can actually reduce the severity of fires such as the one burning in northern California.

Sounds great! But, what if you live near a forest scheduled to burn? Though it is called a “controlled burn” I would certainly be skittish about the combination of control and burn. Fires can be extremely dangerous, but scientists utilize many tools for tracking weather and wind patterns prior to burning. They have extensive topographical information that allows them to track the path of the fire. There are also many resources available for homeowners.

Do the risks of controlled burning outweigh the risk of uncontrollable wildfires? Ultimately nature has the power to override any hesitations I may have about whether I want a fire in my backyard. So I have to ask, what is my role in fire and forest ecology?

Those compact fluorescent light bulbs (CFL) should keep saving you money on your electric bills for many years. When they do burn out your need to safely recycle them. I burned one out in just one day because I had a dimmer switch.

Starting today I can recycle my CFL bulbs for free at any Menards store in Minnesota thanks to The Center for Energy and Environment and Great River Energy.

There’s another story in the news about reintroducing wildlife to Scotland.

Unlike that last story, however, this one has heart and a moral. The heart, to be clear, is a beaver, and the moral is this: don’t just go tossing your beavers around, because they might get full of salt water and die. Take that to heart (actually to heart this time, not to beaver).

The story goes thusly:

First, the mystery. Beavers were believed to be on the loose in Scotland in April. Now, here in Minnesota that’s not such a big deal—out of control beavers are pretty much the norm. But in the British Isles, where beavers were hunted into extinction 400 years ago, it’s apparently a horrifying prospect. You see, the punishment for loosing a beaver is two years in prison or a 40,000 pound fine. Fortunately for the Brits, there seemed to be only a couple of beavers to deal with. “They are by themselves,” said the BBC’s beaver expert of the situation, “spring is in the air, [and] they might be looking for mates which they're never going to find.”

Remember, in Britain, “mates” means “friends.” Why couldn’t these beavers ever find friends? What were they running from? Therein lies the real mystery, but the Scottish police became distracted by more superficial elements of the case: “We must capture the beaver to find out if it’s clean and got no diseases,” said constable Douglas Ogilvie.

No doubt everyone just wanted to forget about the case, but that became impossible in May, when a dead beaver was found on a Scottish beach. Despite suggestions that its remaining there might improve the beach, the corpse was removed for the purpose of investigation.

Beaver autopsies being what they are (complicated and time-consuming, apparently), it was only this week (one month later) that the results finally came in: the beaver drank itself to death—possibly because of loneliness—on seawater.

An official program to reintroduce beavers to Scotland was announced last month, but this poor, salty rodent was probably intentionally released by a numbskull working on his own.

“Beavers need freshwater,” points out a local wildlife crime officer, “ and the only open water this one found was the sea. Its stomach was found to be full of water, otherwise it was found to be a healthy animal.”

And so we’ve come to the tragedy portion of our little tragimystery. A little beaver, far from home, set loose like White Fang, only to accidentally poison itself. What a bummer.

Let this be a lesson to you: just because you think something is a good idea doesn’t mean you’re not an idiot. And also be kind to beavers, because they’ve had a rough spring. And, um, don’t put them in salt water.

OMG! Cute kitten! LOL!: I r poisnin ur brain!

I was wrong!

You know, I spend so much time being right, that the occasional (very, very occasional) situation in which I’m slightly…not right, is actually pretty refreshing. It’s like, oh, I don’t know, getting halfway to work and realizing that you forgot to put on pants, and then linking, “Hey, who cares? And it’s a warm day!” It’s liberating.

Some days I can’t help but feel overwhelmed by cat feces. I don’t even live with a cat at the moment, but I’m aware that there are millions of cats out there, and they’re all addicted to pooping (just try forcing a cat to go cold turkey—total junkies for the litter box). There’s just so much cat poop in the world, and none of it smells very good, and I don’t want to touch any of it, and its very existence drives me to distraction.

Nobody else seems to care very much. Here I am, dreaming of cats that emit water vapor and rose-scented hydrogen gas as their only waste products, and the rest of the world seems content to live with a planet suffocating under the weight and odor of cat effluvia. I imagine that Leonardo felt the same way. It’s a lonely existence.

Perhaps no longer.

Toxoplasmosis gondii is an interesting little gooball (gooball is a term of my own, so don’t use it in class, or you’ll get an F and I’ll sue you). It’s a protozoan parasite, capable of living in nearly any warm-blooded mammal (it’s estimated that over 20% of the U.S. population carries the parasite), although its infectious form—responsible for about a third of all deaths from food borne illnesses—is only carried by cats.

The parasite has some interesting tricks up its sleeves too. It seems that when a rodent is infected with T. gondii, it loses its fear of cats. And a little mousey with no fear of cats is a little mousey that gets eaten, successfully passing the parasite back to its favorite host. Weird.

I also have very little fear of cats, which lead me initially to believe that I was a carrier of the disease. But a study covered in this article details a whole different set of symptoms in infected humans (of which, again, there are many). Men who are infected “have lower IQs, achieve a lower level of education and have shorter attention spans. They are also more likely to break rules and take risks, be more independent, more anti-social, suspicious, jealous and morose, and are deemed less attractive to women” An unsettling portion of this description applies to me, and so it’s possible that I may still be infected.

Infected women, on the other hand, are generally “more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls.” So, you know, it turns out that kittens are a good gift item after all.

And if that isn’t enough to get people thinking about cat feces, it turns out that some of human’s favorite animals, aquatic mammals, are just swimming in toxoplasmosis. How do you like that? The appearance of the parasite in marine mammal populations (including whales, dolphins, otters, sea lions, and seals) seems to be relatively recent, but it is estimated that up to 17% of sea otter deaths alone could be attributed to toxoplasma.

So how are sea creatures across the world becoming “infected by a parasite that is spread primarily through the consumption of infectious cat feces and infected meat”?

(That quote, by the way, comes from a microbiology researcher from Boston, and, if you remove “and infected meat,” is the winner of the best quote of the day award.)

Anchovies. Probably anchovies. The little fish are filter feeders, and could pick up the parasite before beginning extensive migrations, spreading the disease to the many anchovy eaters of the oceans (people who eat anchovies are safe, because heat kills the protozoa). Just how the organism is getting to the anchovies remains unclear, but it has been proposed that the problem has to do with cat feces-contaminated runoff.

So there. Like sea otters and dolphins? Then start thinking about cat feces. I don’t propose that you do anything about it, but I do want you to obsess over it. You won’t be alone.

Also, especially if you’re a guy, keep that stuff out of your mouth.
