Ocean dead zones threaten planet
The spread of oxygen-starved dead zones in the oceans, a graveyard
for fish and plant life, is emerging as a threat to the health of the
planet, experts say. For hundreds of millions of people who depend on
seas and oceans for their livelihoods, and for many more who rely on a
diet of fish and seafood to survive, the problem is acute. Pollution,
particularly the overuse of nitrogen in fertilizers, is responsible for
the spread of dead zones, environment ministers and experts from more
than 100 countries were told. The number of known oxygen-starved areas
has doubled since 1990 to nearly 150, according to the UN Environmental
Program (UNEP).
On land, nitrogen boosts plant growth. But when it washes into the sea
in rivers and rainwater overrun, it triggers an explosive bloom of algae.
When these tiny plants growing on the ocean surface sink to the bottom
and decompose, they use up all the oxygen and suffocate other marine life.
With oxygen depletion, fish, oysters and other marine life eventually
die out along with important habitats such as sea grass beds. UNEP said
efforts should focus on cutting back on overuse of nitrogen to bring the
seas back to life. (Agence Free Press)
NC forests falling fast
More than a million acres of North Carolina forest disappeared since 1990
as urban areas gobbled up land for suburbs, shopping centers and highways.
Foresters expected a loss of forest to urban growth, but the rate of loss
was nearly twice as fast as expected, a US Department of Agriculture Forest
Service survey indicates. The latest Forest Service inventory surveys
forest growth, harvests and ownership between 1990 and 2002.
Wake County and the Piedmont, the states 35-county midsection, have
seen the most dramatic change. Wake, one of the states largest counties,
lost 78,964 acres of timberland, the most of any county in the state.
Buddy Clayton, owner of Clayton Logging of Durham, said most of the timber
cutting he has done in the past year has been to make way for development.
Forests cover more than 18.3 million acres in North Carolina, roughly
59 percent of the states land. That is 5 percent less than in 1990.
It also is the least forestland since the 1930s, when land was being cleared
for agriculture, said Will McDow, a forest economist with Environmental
Defense. (Charlotte News & Observer)
Japan to reject GE wheat
Japanese consumer groups warned the US last week that the country would
reject US wheat products if Monsanto Co. releases a controversial genetically
engineered (GE) wheat variety. Representatives of the Consumers Union
of Japan, along with several other Japanese environmental and consumer
groups, met Mar. 26 in North Dakota with state and federal agricultural
leaders, presenting them with a petition signed by 414 Japanese organizations
urging a rejection of GE wheat.
The delegation was in North Dakota because the state is the top US producer
of hard red spring wheat, and is the planned US launching pad for Monsantos
biotech wheat product. Japan is the No. 1 buyer of North Dakotas
wheat, purchasing about 50 million bushels a year.
The Japanese consumers will... certainly resist GE wheat or GE wheat
products, Keisuke Amagasa, a representative of the No! GMO Campaign
of Japan, said through a translator. We would hope the people of
North Dakota would also oppose the cultivation of Monsantos Roundup
Ready wheat. Amagasa said flour and milling associations in Japan
have said they wont import genetically modified wheat because of
the negative consumer sentiment that has already successfully derailed
some other biotech products. (Reuters)
Bush eases restrictions on old-growth
The Bush administration eased restrictions on logging old-growth forest
in the Pacific Northwest, finalizing a previously announced rules change
that says forest managers no longer have to look for rare plants and animals
before logging. Environmentalists decried the change, saying it would
double logging on federal land in the region and have disastrous consequences
for rare species.
The change was prompted by a timber industry lawsuit and is intended to
boost logging on 24 million acres of public land in Washington, Oregon
and northern California. The timber industry had complained for years
that the so-called survey and manage rules -- which require
study of the potential effects of logging on about 300 plant and animal
species -- are overly intrusive and can take years to complete.
Regna Merritt of Oregon Natural Resources Council Action in Portland,
OR said, They are changing the rules and ignoring the science in
a way that is simply illegal. Theyre going to eliminate protections
for threatened salmon and leave 47 species at high risk of extinction.
The idea of looking before you log was that way we could prevent hundreds
of species from going extinct. (AP)
Rule change endangers salmon
A panel of biologists has charged that a US agency decision to reject
its findings on West Coast wild salmon threatens the fish with extinction.
At issue is whether salmon raised at government hatcheries should be counted
as wild salmon. Currently, the National Marine Fisheries Service (NMFS)
includes hatchery fish in its general counts but excludes them when considering
salmon runs for listing under the federal Endangered Species Act.
In September, Judge Michael Hogan of the US District Court in Eugene,
Or., ruled that the federal regulations for counting fish are unworkable.
He said hatchery-reared salmon should be included with wild salmon in
determining the size of a given salmon run.
Because the numbers of hatchery fish are large on many rivers that support
small populations of wild fish, the ruling could result in the de-listing
of many runs currently considered endangered. That move has rankled members
of the agencys Recovery Science Review Panel, a federally authorized,
independent board of six fisheries biologists and ecologists. The panel
recommended that NMFS respond to the judges ruling by excluding
hatchery fish from its general fish counts, but the agency rejected the
recommendation. In a paper published Mar. 26 in the journal Science, the
six panel members warn that several runs of coho and chinook salmon ultimately
face extinction if they are removed from protection under the endangered-species
law. (San Francisco Chronicle)
Global warming out of control
Levels of carbon dioxide in the atmosphere have jumped abruptly, raising
fears that global warming may be accelerating out of control. Measurements
by US government scientists show that concentrations of the gas, the main
cause of climate change, rose by a record amount over the past 12 months.
It is the third successive year in which they have increased sharply,
marking an unprecedented triennial surge.
Scientists are at a loss to explain why the rapid rise has taken place,
but fear that it could show the first signs that global warming is feeding
on itself, with rising temperatures causing increases in carbon dioxide,
which then go on to drive the thermometer even higher. That would be a
deeply alarming development, suggesting that this self-reinforcing heating
could spiral upwards beyond the reach of any attempts to combat it.

Indians fight water privatization
At a meeting Mar. 22 to mark World Water Day in Indias parched capital
New Delhi, experts from government bodies and nongovernmental organizations
formed a peoples front to counter growing water privatization by
multinational companies (MNCs). Around 500,000 residents are expected
to sign a signature campaign now underway to force the government of Delhi
to resolve problems of water-shortage and stop MNCs from controlling the
precious natural resource in this city, which is gripped by a water crisis.
If that doesnt work, we are going to hit the streets,
threatens M.K. Mohanty, the chairman of the Bhagidari Apex Body, an organization
underlining the role of citizens participation in policy matters
such as water and power. Delhi, a city with a population of 13.78 million
people, faces a water shortage of 200 million gallons per day. People
fear that if MNCs are allowed to take charge of water, prices will shoot
up, making the resource more inaccessible for the citys majority
poor population. (One World.net)
Contamination closes mine
Australias Ranger uranium mine and processing plant have
been shut down after worker complaints of uranium-contaminated drinking
water, majority owner Rio Tinto Ltd. said Mar. 25. Operators aimed to
resume mining as early as later in the day, but now estimate it will take
until at least the weekend to complete investigations with government
regulators into the cause of the contamination. The number of staff complaining
of mild symptoms after showers that may be related to the contaminated
water had risen from two to three, Rio Tinto subsidiary Energy Australia
Ltd said in a statement. The mine and plant employ about 200 workers.
It appeared that an erroneous connection was made between the potable
water line used for drinking and washing and the water line used in processing
the uranium, a spokeswoman said. The centers researchers said the
water was found to contain levels of uranium up to 400 times safe drinking
levels, but Rio Tinto said it had been assured by health officials that
the contamination posed no health risk to workers and that the water supply
of a nearby town was not affected. The plant treats low-grade uranium
oxide which is then stored in barrels before being shipped to North America,
Japan and Europe, where it is enriched and used in nuclear power generation.

Herbicide sprayed in protected areas
Fumigation with glyphosate herbicide in areas of Colombia that are protected
for their biodiversity is part of the joint Colombian-US effort to eradicate
illegal drug crops. But it has come under fire for endangering the environment
and the health of people who live in those areas. Glyphosate is a broad-spectrum
herbicide, which makes it particularly inappropriate for use in areas
set aside to protect species, say critics of the fumigation operations.
The US Congress approved funds in December for spraying illicit drug crops
in Colombias natural parks.
The fumigation effort, said the expert, is part of the governments
strategy to fight drug trafficking through programs supported and financed
by the US and which have not been very successful. In addition
to glyphosates potential harm to the biodiversity of the protected
areas, there are the socioeconomic problems confronting some 800,000 indigenous
peoples and peasant farmers living in those areas, said Senator Jorge
Robledo, of the leftist Independent Labor Movement.
They are families that are cornered by the lack of alternatives,
who have to grow illegal crops, facing the risks entailed in breaking
the law. And the government aims to fumigate as if they were insects,
said the lawmaker, who stressed that the bulk of the profits for drug
traffickers comes from sales in the industrialized drug-consuming countries,
led by the US.
The decision also violates several international treaties, like the Convention
on Biodiversity, ratified by Colombia in 1994, and convention 169 of the
International Labor Organization, which protects the integrity of indigenous
communities, and violates other instruments related to the protection
of forests and wetlands, he said. (Tierramerica)
