"When we try to save species like the antelope
we generally do so by setting aside more islands, national parks. A recent
study by the ecologist William D. Newmark found that in the United States,
fourteen western national parks are too small to save all the mammals that once
lived there. The smallest reserve in Newmarks study, Bryce Canyon, 144 square
kilometers, has already lost more than a third of its mammal species. Yosemite,
at 2083 square kilometers, had lost a quarter of its species even before the
fires of the summer of 1988."
"Parks this size are supposed to be arks. They
are meant to carry the nation's wildlife, including grizzly bears and antelope,
through the next millennium and beyond. But it is now clear that very few parks
on earth are really large enough for the purpose. In the American West, only
the very largest assemblage of contiguous parks, a constellation of preserves
that Newmark calls Kootenay-Banf-Jasper-Yoho, will do the job.
Kootenay-Banf-Jasper-Yoho is 20,736 square kilometers, slightly larger than the
state of New Jersey. According to Newmark, it has not lost any mammals,
yet."
If the giant parks of the West are too small,
what about the parks of the East, or the vest-pocket parks in Europe? Creatures
that depend upon those arks may not last the next century, much less the next
millennium. 'We thought we could put a wall around nature and preserve it,'
says one ecologist. 'But we were wrong.'"

Information on the ecology of ANWR and energy
related issues. http://www.ucsusa.org/environment/bio.anwr.update.html
The United States president is flexing his
muscle. The ANWR issue boils down to a power play in which he intends to once
and for all show that the American government has zero regard for ecology. The
recoverable oil amounts to a 152 day supply spread out over fifty years. The
benefit in oil is negligible while the benefit of demonstrating political power
is maximal.

" The Current Energy Crisis Americans
consume 25 percent of the world's petroleum but possess only two percent of the
world's supply. In 2000, the United States imported 54 percent of its oil
products, sending nearly $200,000 overseas each minute. Depending so heavily on
energy imports leaves Americans vulnerable to oil's price volatility. After the
energy crisis of the 1970s, most areas of the economy reduced their reliance on
oil substantially. Today, only two to three percent of US electricity is
generated from oil. Thus oil from ANWR would have virtually no impact on US
electricity-generation issues, including California's electricity crisis.
Estimates about ANWR's oil potential vary widely, although they almost all
use the same study from the US Geological Survey. Using data compiled in 1998,
the USGS study estimated that only 3.2 billion to 6.3 billion barrels would be
"economically recoverable" from the refuge over the 50-year life of the oil
field (USGS Fact Sheet 1998). This 3.2 to 6.3 billion barrels represents a mere
six- to eight-month national supply. Or put another way, 3.2 billion barrels is
only enough oil to fuel the US economy for seven months (Energy Information
Administration, 2000). [Note: Market prices, of course, determine the amount of
economically recoverable oil, which is defined in the USGS report as "That part
of the technically recoverable resource for which the costs of discovery,
development, and production, including a return to capital, can be recovered at
a given well-head price" (USGS 1999).] On the other hand, proponents of
drilling claim that the ANWR recoverable amount is in the 10 to 16 billion
barrels range. The USGS, however, calculated only a five percent chance that
there are actually 16 billion barrels in the coastal plain and surrounding
area; and only a portion of that oil -- however much it actually is -- could be
recovered economically (USGS 1999). Also to be considered is the reality that
even if ANWR were opened to drilling immediately, the oil would not reach
refineries for another 10 years, and it would take approximately 15 more years
before the region reached maximum production levels (EIA 2000). Even then, over
its 50-year lifespan, ANWR would contribute less than one percent of the oil
this country will consume. Furthermore, many drilling proponents try to
downplay the impacts by stating that only 2,000 acres will be affected -- yet
this acreage is spread over 35 discrete sites on the coastal plain, requiring
roadbuilding and pipeline construction between the sites and between ANWR and
Prudhoe Bay facilities (USGS 1999; USFWS 2001)." http://www.ucsusa.org/environment/bio.anwr.update.html
Scientists for a Sustainable Energy Future in, An Open Letter to the American
People,May 18, 2001, described the opening of ANWR this way;
Opening the Arctic National Wildlife Refuge to oil
exploration will not improve our energy security, nor will it have any impact
on the price of gasoline. The economically recoverable amount of oil in the
Refuge is just 152 days of supply for the nation. More importantly, if we
started drilling in the Refuge today, the Department of Energy projects that by
2020 it could supply 1.4 million barrels per day. By then world oil production
will be in the range of 100 million barrels per day. The Refuge would amount to
about 1 percent of global oil supply, and thus have a trivial influence on the
ability of oil exporters to influence prices. |

Population Graph

This little graph shows the increase in human
numbers in the last few thousand years. In this case, the distance from 1,000
million to 7,600 million is 7.6 times the distance from zero to 1,000 million.
7.6 billion is demographers' mid projection. Graph curve is from Learning
Tools, KQED TV, San Francisco, a PBS educational tv station. Overpopulation
denialists right and left have asked about the source, so now you know. The
leader of the Task Force on Amphibian Decline living in Britain objected
calling the graph extreme and, "off the scale." But it isn't. It is simply
demographer's mid projection.
Usually when such a graph is drawn, a short
time scale is used. But an evolutionarily significant time scale can more
easily show relevant amounts of increase per unit of time.
The distance from 1,000 million to 7,600
million is 7.6 times the distance from zero to 1,000 million. The graph is an
accurate representation. |
