In a statement, Grasby said, "In addition to these volcanoes causing fires through coal, the ash it spewed was highly toxic and was released in the land and water, potentially contributing to the worst extinction event in earth history."
Grasby afirmou que: "Ademais de que estes volcáns causasen lumes por medio do carbón, a cinza que vomitaban era moi tóxica e foi liberada na terra e na auga, contribuíndo potencialmente ao peor evento de extinción da historia da Terra."
