This clay slip work by Charles Schneider alludes to invasive species (the Crown Of Thorns starfish has been somewhat famously a destructive force on the Great Barrier Reef, which is presumably what's referred to here), as well as to humanity's impact on the environment.

Addendum: My personal opinion is that Facebook is a sociopathic organisation that steals other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so. Facebook going out of business would IMO be a net gain for humanity.
