You know, this sort of reminds me of what happened when photosynthetic organisms first showed up on Earth. They triggered a mass extinction by filling up the atmosphere with their waste products (oxygen, which was toxic to most lifeforms at the time), until the creatures that survived maneged to evolve to live off of that waste.
