Epistemology of measurement in non-human animal consciousness

As I assume to begin with, animals with a high level of consciousness, are those beings which are more dependent on their materialistic ecological circumstances than those with less cognition. The most obvious support for this factual claim is the yet still unofficial unit of geological time named the Anthropocene Epoch demarcating human devastation of earthly resources, whereby there is no doubt which species on earth is the most materially dependent. Notwithstanding, we need to keep things quantitively in perspective. Of the 545.8 gigatons of biomass on Earth of which most is plants, animals make up 0.47% while humans only 0.01%, bacteria reigns supreme with 12.8% of total.
