I came across a really striking graphic today on The New York TImes, Are We in the Middle of a Sixth Mass Extinction? by Bill Marsh associated with the OpEd Protecting Many Species to Help Our Own. The credit for the image is a little ambiguous (is just the data from IUCN or is the entire graphic?). What do you think – is this a helpful way for you to visualize this information?

I guess its a ‘tip of the iceberg’ thing… scary!!
