Two innovative initiatives to address climate change have gained attention in the U.S. The first involves the potential use of corn-based ethanol to fuel passenger jets. This move is supported by the U.S. airline industry and agricultural groups, envisioning a future where renewable fuels from crops grown across the Midwest could power planes. The second initiative focuses on the conversion of cow manure to fuel, which has been identified as a growing climate solution. However, critics raise concerns about the impact of this practice on local communities, highlighting issues such as air pollution and health problems in areas affected by the stench of cow manure. These efforts underscore the increasing momentum to explore alternative, sustainable fuel sources and address the environmental and health challenges associated with traditional energy practices.
