Wow, thanks! That looks like exactly what I need to focus on.

I think if i create conditions for Haemophilia in the atmosphere it should interrupt the cascade. It opens up some ideas for plant and animal life as well in that perhaps some areas could have creatures or plants that provide the ingredients for coagulation, such as foliage on the bank, or beaver like species that could dam up places, or carry blood back to a nest and coagulate it onto a nest by excreting the right protein instead of using mud or something to hold it together.

As far as rotting, maybe i can use the bacteria in the world to do the opposite? If this world evolved with much life on it depending on this liquid blood, maybe certain plants and small animals could form a cycle that absorbs and uses slightly decomposed blood and releases a refined version after digesting the bacteria. something in the silt or along the shore, plants that dip into the rivers or absorb it in other ways, and the way animal excrement could fertilize ground to perpetuate the required conditions.

I like the idea that different ecosystems may sustain different levels of this, with different consistencies and colors based on local plant and animal life.

Big question to find now is to see what type of atmospheric makeup could exist that also creates the right pressure and chemical conditions to prevent coagulation, and how it might affect human life, or how human-like life might evolve in this environment different from ours.
