The hypothesis has the advantage of explaining the mass extinction of plants, which would have added to the methane levels and should otherwise have thrived in an atmosphere with a high level of carbon dioxide.
A hipótese ten a vantaxe de explicar a extinción en masa das plantas, as cales se engadirían aos niveis de metano e, doutro modo, deberían ter prosperado nunha atmosfera con alto nivel de dióxido de carbono.
