"fast-fired litany"
In a biological conference, Artist Mark Dion presented an installation which was some kind of dictionary, displaying the meaning of certain words like Biocides, Caroline Parakeet, etc. which were all somehow in connection with human interventions in nature. Sian Ede describing this artwork says
Dion’s fast-fired litany is charged with energy and wit but, above all, a sense of personal responsibility and desire for action. The world doesn’t need more wringing of hands. It needs science.

Does "fast-fired" mean "harsh, stark, and straight"?
How about "litany"? Does it imply "the list of words" or in other words "Dion's dictionary"?
Solution 1:
Litany is defined in Merriam-Webster as;
a long list of complaints, problems, etc.
Fast-fired, based on the context above, means the litany (a list of compliants about the fact that humans are not doing enough for environment/nature) was expressed in a very enthusiastically high voice at a very fast pace.
The adjective, fast, is used when descibing a rate of a machine gun which fires multiple rounds of ammunition in a second.
"Fast-fired" is a metaphor to describe not only his enthusiasm and energy in an effort to change the people's opinion on environment/nature, but also the way he expressed his opinion.
