Gigadead 

Gigadead is a classically-based Speed Metal or Death Metal band from Minnesota, USA. They formed around the year 1990. The main writer is associated with a Kublai Khan member (they had an ex Megadeth guitarist). These same musicians (Idso, River and Pelton) also have ties with the main writer from Kronk and Realm (Milwaukee, Wis). Unlike Bay Area California bands though, Gigadead's style has always seemed more closely related to Scandinavian Death Metal or Germanic Speed Metal.

gigadeath 

The cataclysmic death of a billion people or more. This is equivalent to one thousand megadeaths. This does not need to occur in a single event, but from a connected cause. This word was derived from "megadeath", which was coined in 1953 to describe the results of nuclear war. In contrast, "gigadeath" was coined to describe the more massive catastrophe of industrial civilization combined with peak oil, global warming, ecological degradation, and explosive population growth overshooting the global carrying capacity.

"Abrupt climate change would inevitably lead to gigadeath."

"Humans can live sustainably on this planet, but only after a few gigadeaths."
