Click pdf 4 for Why Conservation Goals
Of 10% are Not Enough
(Conservation goals that once envisioned saving species
and representative samplings of habitat are almost certainly
insufficient to conserve ecosystem function. And at some
point during the 90% eradication that current 10% policies
envision and may permit, an inevitable tipping point will
almost certainly be crossed leading to eventual collapse of
the remnants themselves.)

and Unintended Consequences
(We are living at a time when each of humanity’s added
billions is impacting one natural system after another, in-
crementally, and in most cases, repeatedly – again, and
again, and again. And some
of these many impacts may
transgress critical thresholds or tipping points or result
in unintended and possibly irreversible consequences.)
