Some interesting points, although the first one about the feeding of a hungry African village seemd like so much fluff to me. While that may be true, it's not to suggest that there isn't enough bio-production to feed the world. As we should all know by now, the US produces something like 5 times the amount of grain neccessary to feed the world, and dumps a lot of it right into the ocean to keep prices level. Finding a use for the excess production capacity of the US only makes sense to me, although the deforestation of the rainforerst is a real problem. However, again, the article tends to imply that it is being done in order to provide biofuels. I would wager that the rainforest would be cut down to produce ANY cash crop imaginable in most countries, and as in Africa, the problem is not the biofuel market but the socioeconomic factors that make it impossible to get food to Africans and better economic opportunity to Latin Americans. The final item that I would really like more info on, is the statisic about biofuels producing only about 70% of the energy used to produce them. That may be true, or may not, but I would like to know what they are counting as energy-- it is soley transportation & processing energy, or are they including the converted energy of sun and fertilizer? One would think not, but then again, ya never know.

It is true that more efficient autos, mass transit, & reduced emissions are much more the answer than better fuels. I agree with that %100.

And on that note, Kudos to you and Jessi for becoming bike commuters. You guys rock!

What I like about the article is the implication one shouldn't think that by using bio-diesel they have done their part for the environment and that they are no longer polluting it. As an example the 13% reduction of emissions. Chinese car company's already demand that from their standard fuel using engines.

I agree with you about the rain-forest. Any cash crop will cause deforestation, but to think that it is accuring due to the bio-diesel you might be using kinda defeats the purpose of using bio-diesel. I think the feeding of african villages is intended to show how much crop is necessary to produce the fuel, not how we might be wasting resources that could be fed to starving people.

Overall I think it is an eye-opener as to what we use in order to save the environment may not be as helpful as we would like to imagine.
