econlife - The City That Has to Keep Its Garbage by Elaine Schwartz


In a section of Southwest Alaska, as big as the state of Illinois, you can visit Bethel. A city of 6,500 people, it is the area’s metropolis. For medical care, for shopping, Bethel is where you go. Nearby, 56 Alaska Native tribes live in small groups of several hundred or so.

Visiting Bethel is not quite so easy. Because it is located on a subarctic tundra wetland with a network of ponds and streams, it never connected to the state’s road system. Instead, the only way to access the city is by plane or boat and sometimes a truck when the river is frozen.

You can see that Bethel is in the middle of a lot of water:



The necessities do come in. Cargo planes and barges bring their food, medicine, and cars. However, moving anything in the other direction is the problem. Except for people, little leaves Bethel.

Garbage Problems 

It’s too expensive and too inconvenient to ship garbage out of Bethel. So it stays there.

A typical backyard has piles of junk. There are oil drums, wooden pallets, all sorts of items under large tarps. At the landfill, you can find the spare parts you need from the refrigerators, the stoves, and anything else that was abandoned.

To all of this we can add weather conditions that are especially unkind to local roads. The ice that freezes, melts, and then refreezes creates an unimaginable number of potholes and cracks and heaves. The result?  Hundreds of dead cars. Vehicles have been left on roads, in public parking lots, and especially at the airport.

Our Bottom Line: Incentives

So yes, in Bethel the incentives can be unusual. You place your junk in your backyard. You abandon your dead car. And the taxi cab business is thriving. At 59, Bethel has (reputedly) one cab for every 110 people because people prefer not to drive their own cars in bad weather and the city’s visitors need a cab when they arrive by plane or boat.

Some say that our incentives on the earth could be more similar to Bethel than we realize. We just do not see our junk piling up.

econlife - How Legos Discovered It’s Not Easy to be Green by Elaine Schwartz


Many of us are happy to use fewer plastic straws. But elsewhere, it’s tougher to cut back.


Bio-Based Plastic Legos

We know what we expect from a Lego. They all match, attach, and detach perfectly. The colors of all the reds, the greens, and the blues are consistent. Falling, they are supposed to remain attached (mine never do) and they should not biodegrade or contain harmful chemicals.

Since plastic makes their precision possible, the goal is a plant-based plastic that creates fewer emissions than petroleum. So far, Lego has successfully made bio-based plastic foliage and dragon wings. However, the corn they tried was too soft for bricks. Wheat had color problems. And they could not achieve the perfect grip.

Below, Lego shows how they could use sugar cane:




Petroleum Products

Right now, petroleum is in an endless list of everyday products. Ranging from aglets to yarn and including tires, mops, aspirin, and crayons, the 6000+ products that contain petroleum are everywhere.

Shoelace aglets are made of petroleum based plastic:



Meanwhile, petroleum based plastics result from natural gas processing and crude oil refining. Then, looking at crude, you can see below how an entire 42 gallon barrel is used:



Our Bottom Line: Tradeoffs

Less petroleum-based plastic could mean a smaller carbon footprint. Although the EIA said it could not calculate how much of the world’s oil is used for plastic, the amount is substantial. But using less is not so easy. As economists, that takes us to tradeoffs.

When more corn is grown for bio-based plastic, we could wind up with more pollution from fertilizers, less to eat, and higher prices. On the production side, we’ve seen from Lego that we await the breakthrough discovery that creates a functional product. And even then, discarding bio-plastic can be tough. Landfill remains a real alternative, it could be recycled, and some might go to an industrial compost site (if we were disciplined enough to set aside our compostable products). One big concern is that like petroleum-based plastic, the plant version also can wind up at sea.

So yes, as Lego has discovered, it’s not so easy to be green.

My sources and more: Like Legos, creative articles, happily, have become more typical at WSJ. From there, this list of petroleum based products was ideal. But to start understanding bio-based plastics, this National Geographic article was helpful as were this Conversation and the EIA.

Equality: Outcomes vs. Opportunities by Brian McGarry

Two popular themes often pushed in schools are "celebrating diversity" and "preaching tolerance." At first glance, these ideas sound really nice. However, the roots of these messages stem from an ugly past in which people were judged by the color of their skin (or gender/ethnicity), rather than the content of their character. The battle Rev. Martin Luther King, Jr.  and others fought was intended to make these debates obsolete.


Today our schools are filled with children making posters, flying balloons, and drawing colorful rainbow pictures showing the blending of cultures and acceptance of others' beliefs in order to showcase their collective tolerance for one another. This helps create a school environment that discourages discrimination.


"Teachers need to distinguish the important difference between equal outcomes, which inevitably lead to greater government controls, and equal opportunities, which free the individual to succeed and to make mistakes."

Most students have an intrinsic sense of fairness and sharing. When teachers appeal to the idea of equality, students tend to gravitate towards it. Therefore, teachers need to distinguish the important difference between equal outcomes, which inevitably lead to greater government controls, and equal opportunities, which free the individual to succeed and to make mistakes. Simply talking about equality as a global ideal can easily be misinterpreted.

Each year, I do an experiment in my classroom that highlights the problems with forcing equal outcomes. I adjust the grades from a chapter test by rewriting the "new" grade to account for the successes and failures of each student. For example, those who score in the 90s receive an altered grade in the 70s. Those in the 50s jump to the 70s. Seeing the reactions of those who celebrate their sudden fortunes and the anger from those who have seen their intellectual efforts destroyed by a "central authority's" arbitrary decision is quite interesting. Give it a try with your class.

izzit.org's video 2081 presents educators with an entertaining and graphic example of what happens when you force equal outcomes. The students see how equal outcomes drag the successful down, while institutionalizing mediocrity and incompetence. The heavy hand of government is highlighted in this wonderful adaptation of Kurt Vonnegut's dystopian short story "Harrison Bergeron."

The production value matches the important message. My kids watch intently and are actively engaged in class discussion after viewing it. I ask them to compare and contrast the video with Lois Lowry's The Giver, which is another dystopian novel we read.

I think I have about 20 videos from izzit.org. Thanks to izzit, I can show students that rugged individualism and free-market economics are not merely about making money. These principles also help people tear down the many barriers that tend to make people judgmental and intolerant, without the government attempting to equalize all outcomes.

NEW RELEASE....

We have another NEW RELEASE....

As seen on public television!!!

Developing nations turn on the power! 

Electricity is so much a part of our daily routine in the developed world that it’s hard to imagine life without it. It’s much more than just lights and television, or the internet...electricity plays a factor in health and well-being. 

Travel to Issidan Izdar, a tiny village in the Atlas Mountains in Morocco to see what life is like without power. Then visit the neighboring village of Tamayousst, which connected to a power grid several years ago, to see what a difference electric makes in daily life for those in developing parts of world. 


Some fear this increased demand for energy will harm the planet. But what about the harm to people who live without it? Can we object to the developing world’s rise out of poverty and increased standard of living?

New Release: "Power to the Planet"




We need energy for many things, including lighting, cooking , transporting, heating & cooling....But which energy source is the best? What are the trade-offs of each?



Pollution needs to be considered, as well as availability. What else should we factor in as we decide what's best? Is there even such a thing as "the one best source?"


Travel the globe with scholar Johan Norberg, from Morocco to Sweden and throughout the United States, as he explores the pros and cons of the eight main energy sources available to us: coal, oil, natural gas, nuclear, hydroelectric, biomass, wind and solar.
