The things that are "critical" to life on Earth tend to be non-endangered species. The planet has survived a number of mass extinctions where 98%+ of the species perished. Methinks humans are arrogant and self important when it comes to their place in the universe and specifically on this planet. I laughed when Nancy Pelosi claimed she was here to "save the planet." The planet will be here long after humans are extinct. She should focus on saving humans from the planet because it constantly pwns humanity...just ask her most recent victim, Florida.
