https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-26-18-Dietary-Diversity-and-Health.mp3
For decades, we have heard from public health sources that we should eat a variety of foods. Dietary diversity is touted as important for health. However, there has never really been a consensus about what so-called dietary diversity actually is, how it is measured, or how it necessarily is healthy.

September 21, 2018 Accelerating Sugarcane Growth
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-21-18-Accelerating-Sugarcane-Growth.mp3
Brazil is the world’s second largest producer of ethanol fuel behind the United States. More than that, it has the first sustainable biofuel economy, which is based on sugarcane ethanol, not corn ethanol. It is sustainable because of Brazil’s advanced agri-industrial technology and its enormous amount of arable land. Furthermore, producing sugarcane ethanol is far more energy-efficient than corn ethanol. It actually makes energy sense to produce it.

September 20, 2018 A New Way To Store Hydrogen
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-20-18-A-New-Way-to-Store-Hydrogen.mp3
Several major automakers including Toyota, Honda and BMW are betting that hydrogen-fueled cars will be a dominant technology in the future. There are a number of technical and economic problems to be solved before that can happen. Producing hydrogen in an cost-effective and environmentally-friendly way is critical. But beyond that, one of the biggest challenges is the transportation and storage of hydrogen.

September 19, 2018 California vs. Fossil Fuels
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-19-18-California-vs-Fossil-Fuels.mp3
California has led the way in deploying and committing to clean energy for a long time. In August its legislature strengthened that commitment by passing a bill to stop using fossil fuels entirely by 2045. It is the second state to do so, following Hawaii. The bill still needs to be passed by the Senate and signed by the governor. Both actions are expected to occur.

https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-14-18-Yet-Another-Hot-Year.mp3
This summer has seen record heat in many places and some record-breaking wildfires. In short, it looks a lot like the future that scientists have been warning about in the era of climate change. And still some people continue to argue about whether anything is happening to the climate.

September 12, 2018 Emissions From Electric Buses
https://earthwiseradio.org/wp-content/uploads/2018/09/EW-09-12-18-Emissions-from-Electric-Buses.mp3
Municipalities and transit agencies are gradually replacing conventional diesel buses with cleaner alternatives such as natural-gas-powered, diesel-electric hybrid, or fully electric buses. The goal is to reduce the substantial carbon emissions associated with buses as well as reducing unhealthy air pollution. Diesel buses on average get less than 5 miles per gallon as they transport passengers around, so there is plenty of motivation to find more efficient ways to power them.
