Liberias rainforest silently being
destroyed
Catholic priest Robert Tikpo, chairperson of the Save My Future Foundation
(SAMFU), last week defended a damning report of the plunder of Liberias
rainforest by foreign companies. SAMFU is a local forest watchdog organization
based in the Liberian capital of Monrovia.
The SAMFU report observes that some 170 logging companies have intensified
their operations to the extent that they now represent a great threat
to the Liberian forest. At an environmental workshop held in Monrovia
last week, a participant claimed that some companies operate seven days
a week at high speed, felling all kinds of trees without reforestation,
creating erosion problems, and rendering the areas useless for future
industry.
The Liberian logging industry is one of the largest foreign currency earners
for the government. However, rural people, who are direct custodians of
the forest, have not benefited from the revenue generated from the industry.
They continue to live in abject poverty. Eighty percent of the countrys
2.5 million people live below the poverty line of one US dollar a day.
Safe drinking water in the countryside is a luxury and health services
are near collapse as the nations reconstruction and development
stand still, the result of a decade-old war. (IPS)
Fierce blaze threatens Mt. Kenya ecology
A raging fire, suspected to have been started by arsonists, has now burned
over 4,000 hectares (15 sq. miles) of Mt. Kenya forest and is threatening
the Mt. Kenya ecology and some 882 rare plant species, unique to the area,
say government officials there. On Feb. 28 the fire was bought under control
by the Kenya Wildlife Service, forest guards, the Kenya Army, and the
local community. However, experts in Nairobi say the inferno cannot be
extinguished manually, and that only well-equipped airplanes can effectively
contain the raging fire if it does not die out naturally.
The fire came weeks after the new government of President Mwau Kibaki
announced tough measures to stop illegal logging, encroachment of the
forest by neighboring communities, and growing of narcotics inside the
forest. The government has in the last few weeks fired senior forestry
officers in the region for condoning wanton destruction of the forest,
classified as a UNESCO World Heritage Site. (ENS)
Bush aims to slow mercury reduction efforts
The Bush administration intends to roll back efforts to reduce mercury
pollution despite increasing scientific evidence of its health risks,
according to public health and environmental advocacy groups.
Critics contend the administrations Clear Skies initiative would
allow coal fired power plants, the leading US source of mercury pollution,
to emit three times the amount of the toxic substance into the atmosphere
than allowed under existing law. Under the Clean Air Act, mercury emissions
from power plants could be reduced by about 90 percent, reducing the total
to about five tons by 2007. But under Bushs new Clear Skies initiative,
mercury emissions are capped at 26 tons in 2010 and capped at 15 tons
by 2018.
Mercury is the poster child for what is wrong with the Presidents
plan, said Frank ODonnell, executive director of Clean Air
Trust, a nonprofit environmental group. (ENS)
Global warming driving pika losses
The pika, a small mammal that makes its home on the talus slopes of western
mountains in North America, may be one of the first animals to fall victim
to global warming, new research suggests. A study published this month
shows that global warming may have contributed to local extinctions of
American pika populations in the Great Basin area.
A smaller relative of rabbits and hares, with shorter, rounded ears, American
pikas can be heard calling back and forth on high elevation slopes in
the mountains of the western US and southwestern Canada.
Losses of pikas are disturbing because they are often assumed to
be locally abundant and, in decades past, scientists assumed that alpine
and subalpine ecosystems were relatively undisturbed because of their
isolation, said ecologist and primary study author Dr. Erik Beever.
The responses of American pika populations are likely an early signal
of the impacts of climate change in alpine and subalpine systems,
he added. (ENS)
Climate change spurs genetic adaptation in animals
While politicians and researchers debate the realities of climate change,
plants and animals worldwide are already adapting. Red squirrels in Canadas
North now give birth weeks earlier so their young can take advantage of
the shorter winters that have come with increasing global temperatures.
Much of the squirrels adaptation is due to its ability to adjust
its behavior to climatic conditions. But careful analysis revealed an
inherited genetic change that advanced breeding one day per generation.
Four generations have since passed and even if spring comes late next
year, the squirrels will breed four days sooner.
Although this first documentation of an animal changing its genetic make-up
appears to be a successful adaptation to cope with global warming, the
future is still a concern. Squirrels are a highly adaptable species, but
that is probably not the case for many other animals. It is also possible
that the squirrels have already reached the limit of their genetic flexibility,
and even if they have not, they might not be able to keep pace with changing
climatic conditions.
Plants and animals in other parts of the world are also responding to
these changes. Two massive studies published in the science journal Nature
earlier this year found that many species have extended their ranges northward
to keep up with the earlier arrival of spring because of a 0.6° C
global temperature increase in the past 100 years. Scientists believe
a 6° C rise is possible by 2100. (IPS)
