The combustion engine is the culprit, regardless of the fuel. The electric car, coupled with solar/hydro/wind power is the future.

Bio fuels are part of an interim solution for our demand on energy.
Bio fuels are carbon neutral, when farmed correctly.
Existing engines can be converted. Reducing time, resources and money.
Bio fuels should be STRICTLY monitored and grown LOCALLY and not transported great distances.
They are part of an overall solution for energy combined with wind, tidal, solar, hydro, geothermal and much more. No ONE solution will be the best but a mixture based on the local environment.

We already have issues with food. Whatever happened to hydro-powered vehicles? Why are we investing in something that will further damage our environment rather than really cool cars that will, instead, help the environment and put water back in? I'm sure that there's a catch with hydro-powered vehicles, but I don't think that it'll be as large of a toll as taking food out of the mouths of people to power vehicles and create even further deforestation in order to have a means for this end.

i recently did the math. It would require us to use 96% of the US land mass for biofuel just to power the current number of cars on the road.
it takes 300+ gallons of diesel to farm 1 acre of biofuel. 1 acre = 75 gallons of biofuel.

I am against biofuels because it eat's up our food resources, I am a proponent for hydrogen rather than biofuels due to the fact it burns cleanly and overall is safe.

Cars that run biofuels get 25% less fuel economy
Biofuels are still managed by large energy giants. Its called the free market system, and just like oil, its sold to the highest bidder.
The real answer: Better fuel economy cars, mass transit, better driving habits, and alternative fuels for mass production, that are sustainable.

Biofuels not only are responsible for huge amounts of land being illegally converted into crop fields, it also reduces the amount of food available on the markets which in turn raises the price of food across the world. At the receiving end of this trend are the developing countries, who won't be able to afford importing basic foods any more.
We need to focus on renewable energy, not biofuels.

A robust biofuels industry will help reduce GHG emissions from biomass decay of the growing biowaste problems we face now and in the future. It can be used to clean up disaster debris from hurricanes and floods; divert urban waste from landfills; and salvage wood from wildfires and forest bug infestations. Urbanites need this industry to help rural communities become stronger.
biofuels made from recycled products is good. biofuels made from land clearing is bad.
I am for and against. Yes, Biofuels are helping a bit with the problems of global warming, but think of it this way, its still burning fuel. No matter what it is its still going to damage the world some how or another.
Personally, everything should be powered by batteries. Big huge rechargable batteries! Plug 'em in, charge 'em up, hook 'em up, drive away, repeat when necessary. Either that or God above granting us wings. :P
'There will be no food' argument is a falacy. Biofuels are made out of sugarcane (ethanol), sunflower and/or mamona oil (biodiesel). Today, production destined for food is mostly based on corn, soy and rice. It's a new market that opens up, not a change in the current food market.
The use of biofuels does release CO2 in the atmosphere too, obviously. But contrary to fossil fuels, this CO2 is not being introduced in the environment "for free"; instead it is already part of the natural CO2 cycle.
Biofuels MUST come from a waist source or other technology like algae (look into it)
Corn, canola, other plants like these cannot be used for efficient fuel production.
Clearing rain forests makes no sense if your goal is becoming carbon neutral. Neither does hydrogen in the short term. There is no distribution method! At least for now we need a liquid fuel at ambient temperature and pressure.
Biofuel is just the begining! :)
Its time to get the facts straight.
Fact: Life as we know it is carbon based
Fact: The energy cycle involves conversion of CO2 to simple sugars by a process called photosynthesis.
Fact: The Earth is currently in a natural warming cycle not a 100% attributable to anthropogenic sources.
Fact: The greenest phase in the planet's history was also the phase when atmospheric CO2 levels were the highest. This was the age of the giants.
(contd.)
Biofuels it's good idea! I'm voting for!
