> At least 2 billion people globally eat insects in over 113 entomophageous countries though this habit is regarded negatively or as revolting by others [4–6]. More than 1900 species are consumed by local populations globally but insect consumption (entomophagy) shows an unequal distribution.
There's roughly 8 billion people on the globe. Between 2 billion to 8 billion, there's not much room left for exponential growth.
I could find this study from 2015 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4552653/ which says:
