Will human beings, and the earth,
survive?
Lots of scientists are
worried
about this and are trying to
figure
out what to do about it.
A group of nations has come to the conclusion that human
activities have already pushed the Earth system beyond
three of the planet's biophysical thresholds, with
consequences that are detrimental or even catastrophic for
large parts of the world. Scientists have been warning for
decades that the explosion of human activity since the
industrial revolution is pushing the earth's resources and
natural systems to their limits. The new data confirm that 6
billion people are capable of generating a global geophysical
force the equivalent to some of the great forces of nature,
just by going about their daily lives.
Researcher Sander van der Leeuw says, "On a finite planet,
at some point, we will tip the vital resources we rely upon
into irreversible decline if our consumption is not balanced
with regenerative and sustainable activity." Have we reached
the "tipping point?"
Let's hope times don't get
TOO
tough: Sometimes we worry that unknowncountry.com has
reached the tipping point and may cease to exist pretty
soon. We've managed to bring back Linda Howe's science
report for one week, at least, but we need MORE of you to
