Wilson weighs in; corn withers

Kelpie Wilson, environmental editor of truthout.org, writes today on the possibility of corn as fuel. Fuhgeddaboutit, is the short answer.

Citing the Patzek/Pimentel paper mentioned in the lively comments section of biodiversivist's "Bad idea" post, Wilson notes that the current energy bill (great resource on that here) is going to have some interesting results if it's passed -- it will both encourage ethanol production and demand that less fossil fuels be used.

But increased ethanol production will actually lead to an increase in the amount of fossil fuels used: "We would use less fossil fuel and produce less greenhouse gas by burning the fossil fuel directly in the motor vehicle." Yet another reason to take a pass on this year's energy bill as the LA Times editorial board suggests.

Wilson actually concludes that we might be better off using corn for cars, because this would mean less high-fructose corn syrup, which she asserts has an even worse effect than the biofuel. However, it's clear that biofuel is not going to be a feasible solution for the global car fleet, even if demand is significantly reduced. There is certainly low-hanging fruit to be grabbed, but biofuel is going to remain a niche market.

Worldchanging editor discusses optimism and technology

[editor's note, by Dave Roberts] This is part one of a three-part interview. Part two is here and part three is here.

In April, I sat down for a long, wide-ranging conversation with Alex Steffen, executive editor of the (now newly incorporated and redesigned) Worldchanging.com. Gristmill readers likely need no introduction to Worldchanging, an online salon of activists and thinkers dedicated to the proposition that "another world is here" -- that the tools and techniques we need to reverse the global malaise already exist and await only our imagination and willpower. If it isn't on your daily reading list, it should be.

Originally, I was going to run this interview alongside a rather ambitious long-form piece of my own, but as time has passed -- and I really can't believe how much time has passed -- it's become clear that said piece is indefinitely postponed. Since I have a baby due [checks calendar] three days ago, it's unlikely I'll soon have time to return to it.

Lest it get even older, I'm going to go ahead and run it here. There's lots of good stuff in it, but it's very long, so I've broken it into three parts -- I'll publish the first today and the others in coming days.

In part one, we discuss optimism, technology, and the open-source movement.

Does respect for the former help the latter?

A while ago I posted about environmentalism and the religious worldview. I'm afraid that post was overbroad and led to a discussion about whether one can be a religious environmentalist (of course one can) and, more tediously, whether religion is "good" or "evil" overall.

But I had a more specific question in mind. Let me approach it from another direction.

This week Bush came out in favor of teaching "intelligent design" alongside evolution in school science classes.

I've been debating whether to post about this. This is an environmental blog. Is it an environmental issue?

I think it is, if only indirectly, if you accept the following three propositions:

Hurricane Katrina brings a foretaste of environmental disasters to come

Or, try a lab burger.

Several Gristmillians, myself included, believe that going veg is one of many ways to help prevent climate change. That belief is now supported by British scientist Alan Calverd, who wrote in the journal Physics World that "carbon emissions could be slashed by an incredible 21% overnight if we all stopped eating meat" (via edie news centre).

Can't kick the animal flesh habit? Then maybe you want to look into lab burgers -- that is animal tissue engineered in a laboratory:

Writing in the journal Tissue Engineering, Matheny said scientists could grow cells from the muscle tissue of cattle, pigs, poultry or fish in large flat sheets on thin membranes. These sheets of cells would be grown and stretched, then removed from the membranes and stacked to increase thickness and resemble meat.

Using another method, scientists could grow muscle cells on small three-dimensional beads that stretch with small changes in temperature. The resulting tissue could be used to make processed meat such as chicken nuggets or hamburgers.

Sounds appetizing doesn't it? I'll stick with good ol' plant-based foods thank you.
