They look like priceless brooches and are tremendously important to our planet.
Emphases mine:
Living diatoms make up a significant portion of the Earth’s biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of fresh-water lakes.
It’s hosted by three University of Iowa engineers and scientists who are tired of “cropaganda” and is rather entertaining. The latest episode calls the recent E15 Law a “Fart in a Hurricane”.
One of the hosts is an engineer named Chris Jones who also writes a very lively blog with wonderful nuggets like this:
[…] corn ethanol for fuel is stupid. The industry exists by virtue of one reason and one reason only: government policy. The environmental benefits of using corn to produce a liquid biofuel HAVE ALWAYS been more desperation-half-court-heave than slam dunk, it’s lower potential energy when compared to gasoline makes the 10% blend number an obvious head fake, and its dominance of American politics has kept higher energy players sitting at the end of the bench. So why does ethanol get its ticket punched to the Big Dance year after year after year? Politics. Liberal politicians from Joe Biden to Amy Klobuchar to Dick Durban to Sherrod Brown to Cindy Axne to the Iowa City dogcatcher provide all the cover Republicans in general and Iowa Democratic state legislators in particular need to continue force feeding us this rancid cod liver oil until kingdom come.
