Intensified corn production doesn’t generate such arresting sights. That is because it takes a lot of ‘old’ fossil energy to make it: diesel to run tractors, natural gas to make fertilizer, and of course, fuel to run the refineries that convert corn to ethanol. It is possible that scientists can develop new methods of creating biofuels that do not utilize food crops and that are in fact better for the environment than fossil fuels. The Party for Socialism and Liberation is comprised of leaders and activists, workers and students, of all backgrounds. “By 2010 ethanol was up there with animal feed as the largest consumer of corn.” Last year total U.S. biofuel production reached 16 billion gallons a year, and industry projections anticipate continued growth. But in all of these cases, the benefits now seem to pale next to the climate change deficits. For now, that tension may continue to grow. A national voter poll by the American Biodiesel Board released in October 2019 paints a similar picture.

Capitalist production is driven by the quest to maximize profits. An immediate problem related to biofuels is that food products—corn and soy—are being diverted to make fuel. Today, there are nearly 400,000 hectares, and that number is expected to increase. According to some studies, biodiesels emit more of certain pollutants than regular diesel, and biofuels can have a larger carbon footprint than gasoline, depending on where you start in the production cycle. At the time many experts predicted biofuels would provide a renewable source of energy, help reduce the use of fossil fuels, and lessen the risks of climate change. Those numbers haven’t changed much over time. Just as different crops have different yields in terms of biofuel per hectare, wide variations also occur in terms of energy balance and … Industry groups like the Renewable Fuels Association criticized the studies for being too simplistic, and failing to put biofuels in context.

Although these problems have been identified and studied, if not widely discussed, some experts suggest that maybe they don’t matter in the long term. But as President Donald Trump continues to make promises about the future of biofuels, two important questions loom: Should the rest of the country care about what’s going on in Iowa and other corn-belt states? Bloom is off biofuel rose. If poor people cannot afford tortillas or if meat and milk prices start to soar because feed prices have shot up, the capitalists do not care. "When we ask the world's farmers to feed 6 billion people and ask them to produce fuel, that requires them to use additional land," says Fargione. Intractable problems have been encountered in terms of the energy balance of lipid extraction, maintaining suitable growing conditions in open ponds, and the immense volumes of water, CO₂ and fertiliser required to allow the algae to photosynthesise fast enough at large scales.

Thousands have fled the violence and intimidation.
If poor people cannot afford tortillas or if meat … "Any climate change policy that doesn't take this fact into account doesn't work. Critics say this lobbying has allowed the industry to successfully broaden its market without fully informing customers of the potential costs and concerns, which range from reduced gas mileage to increased air pollution. The demand for land has led to right-wing paramilitaries seizing large tracts for biofuel production.
