the new series, 7 Havens, takes place in an apocalyptic setting.

What the fuck did Korra do to fuck this up? She had one job. Did Zaheer commit terrorism again? Was Vatu born again? Did Kuvira try to take over the world again? What the fuck happened?

I reckon Korra will be used a metaphor for the older generations not tackling climate change.
And as for what causes the apocalypse, it is either going to be the evil kite spirit thing getting freed, or something to do with the spirit portals being opened.

She left the spirit portal open.
