Typhon was something all gods feared, and without serious coordination and effort he would've destroyed everything all by himself. Gaea is the Mother Earth. If she wakes, we can expect elementals/primordials to rise and wreak havok. Vulcans would errupt all over the planet, earthquakes and whatnot. But that's not really the big deal. See, the biggest problem is this: They must not kill Gaea!

She is the Mother Earth. If she dies, the planet dies. That's why she must be asleep. It is highly probable that she won't wake. And that everything will end within last few minutes of her awakening. Not even Gods could defeat her, let alone the Great Seven.
