Tasty fish & tomatoes

Fish and tomatoes compete for resources.

Yep, they do, and that resource is water.

The authors of a new report out in this week's issue of the journal Science are reminding folks of that fact.

John Sabo, a biologist at Arizona State University and lead author of the report told NSF News that "Humans may need to make hard decisions about how to allocate water so that we grow the right food, but still leave enough in rivers to sustain fish populations."

His comments stem from the report's findings that human actions--agricultural irrigation, dam construction, and the collective activities that lead to climate change--alter the natural variability of river flows and in the process shorten river food chains, particularly eliminating top predators like many large-bodied fish.

"Floods and droughts shorten the food chain, but they do it in different ways," Sabo explained. "Floods simplify the food web by taking out some of the intermediate players so the big fish begin to eat lower on the chain," Sabo said. "With droughts, it's completely different: droughts eliminate the top predator altogether because many fish can't tolerate the low oxygen and high temperatures that result when a stream starts drying out."

Sabo and co-authors--Jacques Finlay, from the University of Minnesota, Theodore Kennedy from the U.S. Geological Survey Southwest Biological Science Center, and David Post from Yale University--suggest that the fate of large-bodied fishes should be more carefully factored into the management of water use, especially as growing human populations and climate change affect water availability.

According to Sabo, "The question becomes: can you have fish and tomatoes on the same table?"

Last night, bkennedy, a couple other SMM staff members, and I attended the Bell Museum's Cafe Scientifique at Bryant-Lake Bowl in Minneapolis. Robert Twilley, a principal investigator with the National Center for Earth-Surface Dynamics, came to speak about the endangered environment of the Mississippi Delta and the BP Deep Horizon Oil Spill. I didn't expect to get a history lesson, but it's just this kind of broad-ranging perspective that will help us understand what is happening to our environment.

It was frustrating to hear Dr. Twilley recount how, as a result of the 1928 Flood Control Act, civil engineers literally remade the Mississippi River and its delta in response to severe flooding events. While this had the temporary effect of protecting area residents from flooding, the plan neglected an important quality of all coastlines: they're dynamic. As sea level has risen over the last century, diverted sediments no longer replenish key areas of the delta and vast stretches of wetland are drowning--the same stretches of wetland that would protect people in the event of a strong hurricane. As a result of the levees, regular floods no longer wash sediments into the area. To complicate matters, projects such as dams farther upstream have cut the overall sediment supply to the Mississippi by about 50 percent in the last couple centuries.

Twilley emphasized that it wasn't as if people didn't know the problems these strategies would cause; engineers who opposed flood control tried to call attention to the associated risks. But in the wake of disastrous floods, the public demanded visible public works projects and politicians wanted to please them. Engineers who supported flood control saw it as a noble enterprise to control nature and protect people. And so today we have a tricky situation in the delta area. Disasters increase in intensity, and with them, peoples' insistence on solutions grow. But Twilley cautioned that it is imprudent to act on impulse, especially due to a widespread lack of understanding about how coastal systems work, and to our tendency to favor human safety without consideration for the environment that supports our safety. In short, we undermine ourselves.

"Since 1932, the basin has lost approximately 70% of its total land area."

When Hurricane Katrina hit, the same channel intended to give port access to ships funneled the storm surge farther inland. Twilley described how this perfect storm of civil engineering amplified the devastation brought by the Category 3 hurricane. The response to this devastation, rather than stepping back to reevaluate the situation and consider new ways to accommodate both the delta's needs and humans' needs, was to build a surge barrier that does nothing to restore the natural systems that once built and sustained that landscape over centuries. Contrary to engineers' intentions, Twilley asserted that these strategies will only exacerbate rising sea level and storm surge in the future as the wetlands drown further and the coastline moves inland.

Twilley also explained how, more recently, a lack of recognition of the complex systems in the river delta and along the Gulf Coast exacerbated BP's Deepwater Horizon Oil Spill. BP's front end study on the potential impacts of a spill found no cause for concern that the oil would reach the shore. And yet, in spite of booms placed along the coast, the oil did reach the shore, infiltrating wetlands already threatened by rising sea levels and weakened by lack of sedimentation. Thanks to the use of dispersants, the oil is difficult to find and we may not know the full impact of the spill for some time.

This paints a pretty grim picture of the future, but Twilley left us with cause for hope. In one of the areas to which a significant portion of sediment was diverted, the wetlands are actually growing (Atchafalaya). Twilley and his colleagues hope that this and other examples will demonstrate the importance of these natural wetland-building systems and garner support for their plain to mitigate the wetland loss. They want to add river outlets in strategically important places throughout the delta to rebuild the wetlands and help stabilize the landscape. These outlets would only operate during flooding episodes--an approach called controlled flooding (as opposed to the current strategy of flood control), siphoning off extra water and sediment to starved wetlands AND preventing flooding into human settlements. Currently, they're also involved in a project to pipe sediment to areas that need it.

Of course, the new outlet plan won't be without some compromise on the part of humans--some may have to relocate. But given projections of the area for 2100, relocation isn't far off anyway. And the long-term protective benefits of restoring the wetlands might just be worth it.

Climate change. Rising seas. GMOs. Humans have such an incredible impact on Earth's environment that it's clear we're now the dominant force of change on Earth. This situation has even led some scientists to rename this geologic epoch the Anthropocene, or the human epoch. But as we alter, tweak, and pollute more each year, what will it mean for the survival of other species into the future?

According to Dr. Stephen Kress, they can look forward to human stalkers and creepy mechanical scarecrows. Kress began his career in the islands along Maine's coast during the late 60s and early 70s. In response to the loss of bird species diversity on many islands, he decided to start a human-led migration program that would move puffins to some of the islands. Puffins had once been abundant in the area, but their population dwindled due to overhunting and egg harvesting.

Still others accused Kress of trying to play God. “We’d been playing the Devil for about 500 years,” says Tony Diamond, a Canadian seabird researcher who has collaborated with Kress for decades. “It was time to join the other side.”

Amid the skepticism of fellow scientists and the stubbornness of birds, Kress persevered and now boasts growing puffin populations on a few islands. But after several attempts to set natural protections and population controls in place, including a mechanical scarecrow to ward off predators, Kress and assistants continue to monitor and protect the puffins themselves. It's the only way they can maintain the new populations. After all, in a human-dominated environment, we get all the benefits and all the responsibilities--a job some might conclude is for the birds.

We are as gods and have to get good at it.

“…Welcome back, class. Please hand in your essays on the scientific fundamentals of phosphorus-driven eutrophication in the Gulf of Mexico, and note that our exam covering chapter eight, the Biogeochemistry of Acid Mine Drainage, will take place next Tuesday. Today we will be covering fluid bed catalytic oxidation, hazardous waste landfill leachates, and NIMBY. But, first, let’s take attendance: Bueller?... Bueller?... Bueller??”

Say what? “Nimby?” Girl, puh-lease! He just made that up… didn’t he??

It wasn’t long into my undergraduate stint as an Environmental Science major that I came across the word, “nimby.” Actually, it’s not a word at all. It’s an acronym, N.I.M.B.Y., standing for “Not In My BackYard,” that captures an important public attitude that affects environmental policymaking.

NIMBY explains many people’s attitude towards environmental policies, capturing sentiments like,

“That’s such a cool and important idea! As long as it’s not actually happening in my community, that is.”

“Whatever. I don’t care so long as I don’t have to see it everyday.”

NIMBY: Yuck.  Who wants to look out their bedroom window and see a mountain of trash?  Not these guys.

Think About It

Do you like having your trash removed from your home? Most everyone does. But, would you like having a landfill in your backyard? Almost nobody does. This is the classic example of NIMBY. Nearly everyone likes having their trash collected from their property and transported out of sight and smell, yet someone, somewhere has to live beside a mountain of trash. As long as we’re not the ones living across the street from the landfill, most of us are satisfied with this method of garbage disposal. The same idea goes for wastewater treatment facilities as well.

Another classic example is nuclear power. Some people support nuclear power as an inexpensive and “clean” alternative to fossil fuels like oil and natural gas. However, the construction, maintenance, and decommissioning of a nuclear power plant poses risks and creates radioactive waste. Whether or not you think the risks and waste production are acceptable consequences depends largely on your proximity to the plant and/or ultimate disposal site for the nuclear waste.

A recent example of NIMBY is occurring in California this summer as covered in Green, a New York Times blog. In a valley near Santa Clara, Martifer Renewables canceled their plan to build a hybrid solar power plant. Set on 640 acres of agricultural land, the plant was supposed to produce electricity by solar power during the day and biomass burning by night. How sweet is that?? A 24-hour source of renewable energy! The California utility PG&E thought it was a great idea too and signed a 20-year power purchase agreement for 106.8 megawatts, which became part of their energy portfolio. PG&E must obtain 20% of its electricity from renewable resources by December of this year and another 13% (for 33% total) by 2020, as mandated by California state energy goals. Now that the project is canceled, PG&E will have to look elsewhere for sources of renewable electricity or risk missing their mandated targets.

Regarding the canceled project, Martifer executive, Miguel Lobo, wrote in a June 17th letter that,

“We were not able at this time to resolve some of our issues regarding project economics and biomass supply amongst other things.”

What Lobo was likely referring to are the complaints of local residents and regulators who contested several aspects of the project. Chief amongst the complaints was the around-the-clock operation made possible by burning biomass. What exactly were they so excited about? Noise, waste, and air pollution – all realities of energy production, yet things we’d rather not experience ourselves. In short, NIMBY.

Alright, so what?

Now that I’ve opened your eyes to the existence of NIMBY, you might be wondering how it influences environmental policymaking. The easiest answer is that environmental policymakers seek to find a balance between the conflicting desires for new technology like this power plant and local opposition and the NIMBY attitude. Often both sides make compromises and projects move forward on a slightly different path than previously proposed. However, as in the California case of Martifer Renewables, occasionally a project is completely scrapped. Other times, the project proceeds as originally planned. Which of the outcomes occurs depends largely on the organization and influence of the local opposition. In turn, this often raises issues of environmental or eco-justice.

Clearly our modern society cannot exist without landfills or wastewater treatment facilities as smelly and unsightly as they may be. Whether or not nuclear or other renewable energy power plants are equally necessary today is debatable, but it’s not hard to imagine a future in which they will be. If no one agreed to have these facilities in their community, life as we know it would be very different. This begs the question: how do you think policymakers should balance the needs of society at large against the NIMBY attitude of locals?

Agriculture is widely understood to be one of the largest contributors of greenhouse gases in our atmosphere, which is unfortunate for two reasons: 1) greenhouse gases are a driving force of climate change, and 2) last time I checked, people still need to eat.

Specifically, farming is one of the largest contributors of carbon dioxide, methane, and nitrous oxide – all greenhouse gases – in our atmosphere. The four major sources of these emissions include fossil fuel consumption, fertilizer usage, animal farts and poop (no kidding!), as well as land use change (mainly, deforestation). As serious a problem as climate change is, one of the most important truths for environmentalists to remember is that people have needs that necessarily affect the health of the environment. For example, the world’s population is currently well over six billion people who need roughly 2,000 calories from food each day. That’s a lot of food that we depend upon farmers to raise and grow for us every day! And with predictions of nine billion people occupying the Earth in a mere forty years, our global population’s appetite is growing.

However, a June 2010 study published in Scientific American says that farming’s bad rap is undeserved, and actually modern high-yield crop farming has a net reduction of greenhouse gas emissions. Say what??

Here’s how it works: What sustainability-minded scientists from many disciplines strive to do is find ways to limit (better!) or eliminate (best!!) peoples’ negative impact on the environment.

In the 1960s, farmers and researchers began to develop new methods of farming to feed the rapidly expanding population. This has been called the “Green Revolution.” The results of their studies produced modern high-yield farming, which has allowed farmers to produce more food in less space. According to the Stanford researchers, though high-yield farming is possible largely because of fertilizer use – one of the four major sources of greenhouse gas emissions on farms – it prevents land use change in the form of deforestation – another one of the four major sources of greenhouse gas emissions on farms. The key point is that the greenhouse gas emissions caused by fertilizer use is less than the greenhouse gas emissions caused by deforestation, which yields a net reduction. That is, if we had continued with pre-Green Revolution farming techniques, in order to feed today’s population, we’d be using less fertilizer, deforesting more land, and emitting considerably more greenhouse gases than we currently are.

Today, at the Institute on the Environment, the Global Landscapes Initiative continues to focus on seeking ways to secure a healthy land use future for both people and the environment. This includes researching innovative agricultural practices.

Another Scientific American article has it’s own ideas about how to provide food to our growing population: build vertical farms. These futuristic, skyscraping greenhouses are based upon existing hydroponic greenhouses and could reduce fossil-fuel use while simultaneously recycling city wastewater. Hydroponic greenhouses grow plants without soil! Instead, they use mineral nutrients dissolved in water, allowing plants to be grown just about anywhere… including on the 34th floor. According to the article,

“A one-square-block farm 30 stories high could yield as much food as 2,400 outdoor acres…”

That’s a lot of food. A lot. Really? Is it possible? The paper’s author claims it is and that architects, engineers, designers, and “mainstream organizations” are taking note of his vertical farm concept.

A sperm whale: You will never get my precious iron feces! Never!
A sperm whale: You will never get my precious iron feces! Never!Courtesy Pacman
It would be a very special day indeed if a better story than this one popped up. But I wouldn’t ask for that. How could you want any more than this: whale poop fights global warming*.

Sperm whales are the particular focus of this study. The population of sperm whales in the Southern Ocean (the waters around Antarctica) is thought to be about 12,000. (There are more sperm whales in the world, but the study looked at Southern Ocean sperm whales.) Those 12,000 whales are thought to put about 200,000 metric tons of the greenhouse gas carbon dioxide into the atmosphere each year. That’s about the same amount that 40,000 passenger cars contribute each year. Destroy those polluting whales, right?

Wrong! See, it turns out that these sperm whales are also responsible for the removal of 400,000 metric tons of CO2 each year, making up for the amount they produce two times over. Their secret is this: they poop iron.

They don’t only poop iron, but sperm whales poop a lot of iron—each whale is thought to defecate about 50 metric tons of iron each year. That’s over 300 pounds a day! Obviously the whales aren’t pooping out solid iron ingots, though. It’s mixed in with their liquid feces. And that’s important.

The whales themselves don’t remove those 400,000 tons of CO2. They’re removed by phytoplankton. Phytoplankton are microscopic organisms that, like plants, use sunlight and CO2 to build their bodies. And they feed on iron.

The whales have lots of iron in their diets, because of the large amounts of fish and squid they eat. So the iron-rich whale poop is an ideal nutrient for phytoplankton. When the phytoplankton dies, the carbon they contain falls to the bottom of the ocean instead of being released back into the atmosphere. Where more carbon is trapped than is released back into the atmosphere, it’s called a “carbon sink,” and that’s what whale poop and phytoplankton create in the Southern Ocean.

Other parts of the ocean may naturally contain more iron for phytoplankton, but the Southern Ocean is poor in the nutrient, and the microorganisms rely on an iron cycle that the whales apparently play a large part in. More whales, greater carbon sink. Fewer whales, less whale poop, more atmospheric carbon.

Coincidentally, the International Whaling Commission will be meeting next week, to discuss regulations on how many whales can be harvested from the oceans each year. It’s a complicated world, isn’t it?

*I thought about making the headline “Whale poop is ‘green’” but… yuck.

A few weeks ago, I assumed that some of our readers were bored with the same ol’ climate change arguments. I know you know what I’m talking about: the Cuddly-Animals-are-Dying and the Catastrophic-Disasters-Will-End-the-Human-Race arguments come to mind first. Now, I’m not saying there isn’t some merit to these frames, but c’mon! Can’t we get a little variety?

Lucky for you, University of Minnesota professor and Institute on the Environment fellow Stephen Polasky thinks creatively. In April, he gave a presentation on how adopting inclusive wealth could ultimately reduce climate change and its effects. And since virtually everybody likes money, I’m going to go out on a limb and bet you want to know more about the ca-ching!$

Here’s the skinny:

Economists say that just about everything has a monetary value, and how much something is worth plays largely into the decisions politicians make. Scientists like Polasky are increasingly saying that these traditional accounting methods do a poor job assessing value to natural resources, and these mistakes are leading us to make irrational choices. As an alternative, Polasky suggests adopting inclusive wealth theory.

Ready for the good stuff??

Economists and scientists both agree that the environment has worth, called natural capital, but they disagree on how much. In fact, not only do economists and scientists disagree with each other, but they disagree amongst themselves! To be fair, determining something’s worth can be extremely difficult. Because there are already economic markets for some natural resources like trees (i.e. lumber) and metals (i.e. gold), it’s easier to assess their value. Most ecosystem services, however, like the flood control provided by wetlands, are more difficult to put a dollar value on.

Inclusive wealth theory says that our decisions should be made on economic assessments that include true representations of the value of natural resources (difficult as that may be).

Politicians make important decisions regarding environmental policies, including actions that affect climate change. When politicians are choosing between multiple policy options, they are conducting policy analysis. One criterion that politicians pretty much always use is a cost-benefit ratio, or cost efficiency. In order to do that, politicians must determine the value of each policy option and weight the outcome against the rest. (It might sound complicated, but you do this same process informally everyday when you make decisions regarding what to eat for breakfast and whether to walk or ride your bike to school/work.)

Polasky and other like-minded individuals argue that under traditional accounting methods, politicians’ cost-benefit ratios are distorted – they are not accurately representing the true worth of the environment. Furthermore, as a result, we’re making some pretty big, bad decisions. According to Polasky, the solution is simple in theory, but difficult in practice: adopt inclusive wealth theory to more accurately measure environmental worth. If we increase the value of the environment in our analysis, the cost-benefit ratios will change and perhaps favor decisions that are more environmentally friendly. That is, under inclusive wealth, we might finally see how important it is to take climate change-reducing actions such as reducing our fossil fuel consumption, protecting forests from logging, and stopping eating so much meat… or not.

What do you think?

How much $$ is the environment worth to you? What about individual ecosystem services like pollination by bees or decomposition of waste by microbes?

Are politicians doing an accurate job of assessing the value of natural capital?

I'm not going to get into the full parasite extravaganza here, because Wired Magazine already laid it out pretty well, but here's the general idea:

What if some worm eggs snuck into your body through something you ate (something gross)? What if one of them lodged itself in your liver, and, after a little while, started producing embryos of its own? What if it packed those embryos into giant, pulsating egg sacks that flopped out of your eye sockets and hung from your head? And what if those pulsating egg sacks looked so delicious to birds that they would flap down and eat them (and your eyes)?

It can all happen. I mean, you'd have to be a snail for it to happen to you, but still... Leucochloridium paradoxum is out there.

You could be attacked from above at any second. By a shark. Because they are invisible. And you can’t see invisible things. So they can easily attack you.

I mean, you’re not going to get attacked by just any shark. But, really, if there’s an invisible shark hovering above you, about to attack, does it matter what kind of shark it is? That’s like a squirrel wondering if the car that’s about to force its digestive tract out through its lowermost orifice is a Ford or a Toyota. Let’s be practical here.

If you must know, the shark is called a “velvet bellied lantern shark.” (Coincidentally, if you replace “shark” with “head” you have my childhood nickname.)

But the important part, again, is that it can turn invisible.

It’s not quite up to Harry Potter levels, at least—the shark is only invisible from below, thanks to its velvety lantern belly. See, if you’re a weak little prey species flopping pathetically around the ocean (I assume you are), if you see a dark shadow pass overhead, you want to flop pathetically toward some cover, because dark shadows often come from things that can eat you. Like a shark! The underside of this shark, however, is covered with light-producing organs, called photophores, which shine at the same frequencies as the sunlight that filters through the water. That, of course, tricks the other little fishies (and you) into thinking that the shark isn’t there.

It’s more than a little concerning, isn’t it? Don’t worry, though. I’ve been working on a product for just this sort of problem, and I think it’s about ready. It’s an invisible-shark detecting stick. It actually looks a lot like a wooden yardstick, and you can even use it for measuring things up to one yard long, but it’s really meant for keeping you safe from invisible sharks. You use it by holding it above your head at all times. If you feel a pressure on the stick, just look up. If you see a doorway, or a broken light fixture or ceiling fan, you’re probably safe. But if you look up and see only a familiar comforting glow, you should dive for cover. Or, if you carry a firearm, you should shoot wildly into the air above you. Shark crisis averted.

They’re $30. Email me.

Bonobo: Latin name:  Pan paniscus
Bonobo: Latin name: Pan paniscusCourtesy bradypus courtesy of wikimedia.org
The famous Max Planck Institute for Evolutionary Anthropology recently released a new study showing bonobos (Pan paniscus), a species of chimpanzee, communicating their disapproval by shaking their heads side-to-side as if to say NO. This may seem rather simple and uneventful, but until now, there has been no observed behavior in chimps or bonobos that indicates a negative context. Chimpanzees (Pan troglodytes) and bonobos are known to use other head gestures like bowing and shaking up and down to communicate with group members, but the side-to-side NO gesture is actually considered quite sophisticated and ingrained in human culture. This simple gesture is recognizable in most, but not all cultures.

I recently finished up a semester teaching Evolution and many of my students commented on how interesting they found our ape relative the bonobo. Many had never heard of them and were surprised at how similar they were to humans in behaviors and social structures. We frequently here about how closely related we are to the chimpanzee biologically, but culturally, the bonobo's social structure is actually more human-like than that of our chimp cousin. The bonobos have extremely egalitarian and cooperative societies with a rather unusual “loving” way of diffusing social tensions (suffice to say there is a reason why bonobos are not found in most American zoos!) This new study brings us a little closer to our ape cousins and maybe we can learn a few lessons from them in these times of conflict. Unfortunately, these gentle creatures are endangered and need our help. Check out this website for more on Bonobo Conservation.
