This observation was apparently presented at the Evolution 2011 meetings in Oklahoma, but I missed it. Via Alex Wild at Myrmecos comes a report from New Scientist of the discovery of only second species (besides H. sapiens) that raises animals for meat.
Scientists have grown meat in the laboratory for the first time by using cells from a live pig to replicate growth in a petri dish. The advent of so-called “in-vitro” meat could reduce the billions of tons of greenhouse gases emitted each year by farm animals — if people are willing to eat it.
How green is ethanol? The Renewable Fuels Association (RFA), an American lobby for the stuff obviously wants voters and politicians to think it is very green indeed. The association’s cool-coloured website plays down claims that ethanol may actually harm the environment.
