Bio-tech genes spread for miles
A new study shows that genes from genetically engineered grass can spread
much farther than previously known, a finding that raises questions about
the straying of other plants altered through biotechnology and that could
hurt the efforts of two companies to win approval for the first bioengineered
grass. The two companies, Monsanto and Scotts, have developed a strain
of creeping bentgrass for use on golf courses that is resistant to the
widely used herbicide Roundup, which is made by Monsanto.
In the new study, scientists with the EPA found that the genetically engineered
bentgrass pollinated test plants of the same species as far away as they
measured -- about 13 miles downwind from a test farm in Oregon.
Critics worry that the grass could spread to areas where it is not wanted
or transfer its herbicide resistance to weedy relatives, creating superweeds
that would be immune to the most widely used weed killer.
The gene really is essentially going to get out, said Norman
C. Ellstrand, an expert on this subject at the University of California,
Riverside. What this study shows is its going to get out a
lot faster and a lot further than people anticipated, he added.

Oceanic noise pollution kills marine life
The worlds oceans are now so saturated with noise that whales and
other marine mammals are dying, biologists say. The UKs Whale and
Dolphin Conservation Society (WDCS) is launching a campaign, Oceans of
Noise, to tackle what it says is the increasing problem of noise pollution.
The group says key sources of undersea noise are the search for oil and
gas, and the use of low-frequency military sonars. Also, there is evidence
that noise is causing hearing loss in cetaceans (whales, dolphins and
porpoises), injuring them and causing them to strand themselves, and is
sometimes killing them. It also believes excessive noise is seriously
interfering with cetaceans ability to communicate with each other.
The WDCS action plan includes a proposal for an international treaty to
regulate marine noise pollution, and for an independent body to undertake
research. (BBC New Online)
EPA wording found to mirror industrys
For the third time, environmental advocates have discovered passages in
the Bush administrations proposal for regulating mercury pollution
from power plants that mirror almost word for word portions of memos written
by a law firm representing coal-fired power plants.
The passages state that the EPA is not required to regulate other hazardous
toxins emitted by power plants, such as lead and arsenic. Several attorney
generals, as well as some environmental groups, have argued that the Clean
Air Act compels the EPA to regulate these emissions as well as mercury.
The revelations concerning language written by Latham & Watkins could
broaden an ongoing probe by the EPAs inspector general into whether
the industry had an undue influence on the agencys proposed mercury
rule, legislative critics of the proposed rule said.
The Bush administration continues to let industry write the rules
on pollution, and this is just one more example of how they abuse the
public trust, said. Sen. James M. Jeffords (I-Vt.), ranking member
of the Senate Environment and Public Works Committee.

Two-thirds of Caribbean reefs threatened
Most of the Caribbeans famed coral reefs, which besides their natural
beauty also provide crucial protection from hurricanes and contribute
billions to the regions economy, are jeopardized by pollution and
overfishing, a new report warns.
Using a threat index, researchers from the World Resources
Institute (WRI) found that about one-tenth of Caribbean coral reefs now
face very high levels of risk, including the Eastern Caribbean,
most of the Southern Caribbean, the Greater Antilles, the Florida Keys
and the Yucatan peninsula.
There are many different layers of pressure, particularly in the
Caribbean, in addition to the over-arching threats of rising ocean temperatures
and coral bleaching from disease, Lauretta Burke, the lead author
of the report, told IPS.
The WRI report, titled Reefs at Risk, was written in collaboration
with more than 20 organizations operating in the region. It is the first
complete assessment of the state of Caribbean reefs, and the specific
mapping of problem areas will provide an important tool for local authorities
in setting priorities for conservation and natural resource management,
Burke said. (IPS)
E-waste as new toxic trade
Britain is throwing out more than 1million tons of electronic e-waste
such as broken computer monitors and discarded mobile phones every year,
and new government figures show that more than ever is going abroad. Last
year, 23,000 tons of IT and electronic equipment was shipped out illegally,
mostly to China, west Africa, Pakistan and India to be dismantled by hand
for its lead and other valuable toxic contents.
The governments pollution watchdog, the Environment Agency, says
the e-waste exports are worth hundreds of millions of dollars. The agency
admits it has no idea how much of the waste is being deliberately dumped
on poor countries by companies trying to avoid paying increasingly high
disposal costs in the UK, and how much is only technically illegal because
companies have filled in the forms incorrectly. (The

Tundra thaw could accelerate climate change
Dramatic results made public Sept. 23 from a unique 20-year US experiment
are raising the specter of runaway warming above the Arctic tundra that
would accelerate global climate change.
The problem arises because US researchers discovered climate warming might
trigger conditions where tundra decomposition will dump carbon dioxide,
the leading greenhouse gas, into the atmosphere faster than its
soaked up by accelerated plant growth.
This extra carbon dioxide could trigger a positive feedback,
speeding up the rate of global warming even more, warns a study published
Sept. 23 in Nature, the influential British research journal.
If all the carbon currently stored as peat, moss and other ancient vegetation
in the top yard of tundra decomposed, that would boost global atmospheric
levels of carbon dioxide by roughly 25 percent, says Paul Grogan, a Queens
University expert in northern ecosystems. (The

China sets its first fuel-economy rules
Brushing aside concerns from the auto industry, the Chinese government
has set fuel-economy standards on new cars, sport utility vehicles and
vans for the first time, people with copies of the new rules said on Sept.
22.
The regulations represent a broad effort by Beijing to address its soaring
dependence on imported oil, a dependence that has helped lift oil prices
around the world as producers have struggled to keep pace with rising
demand.
The rules set gas mileage requirements for cars, SUVs and mini-vans
based on their weight. The Chinese standards for the first phase are similar
to the averages for most cars now in the United States, with some improvements
mandated for the second phase; the Chinese standards for mini-vans and
SUVs are more stringent for the first phase and much more stringent
for the second phase than what such vehicles now achieve in the US. (New

Russia takes first step in joining Kyoto treaty
Key ministries of the Russian government on Sept. 23 began the process
of ratifying the Kyoto Protocol, signaling that President Vladimir Putin
was preparing to put the landmark global warming treaty to a vote in parliament.
It would be the first step toward allowing Russia to join the 1997 accord.
The Natural Resources Ministry approved the documents Sept. 23, but the
Economic Development and Trade Ministry called for more study of the economic
consequences, indicating that a fight was possible before ratification
could occur. Still, environmental activists said they hoped the issue
could be presented to parliament within the next several weeks.
Russias participation is a crucial step toward implementation of
the protocol, which requires participating industrialized countries to
cut their emissions of greenhouse gases, blamed for what many
scientists think could be a precipitous change in global climate.
The protocol, which cannot take effect unless Russia signs it, aims to
reduce greenhouse gases to 5.2 percent below 1990 levels by 2012.

Acid rain pollution increasing
Emissions of sulfur dioxide, which causes acid rain, rose 4 percent in
2003, but probably will not compromise long-term air quality goals, the
government reported Sept. 22. Coal-fired power plants were the main source
of the 10.6 million tons of sulfur dioxide. That total compared with 10.2
million tons in 2002 and reverted to the level from 2001.
Nonetheless, pollution from sulfur dioxide has dropped significantly over
the past two decades, from 17.3 million tons in 1980 to 11.2 million tons
in 2000, the year before President Bush took office. The total is within
striking distance of lawmakers goal of cutting such emissions to
8.95 million tons by 2010 -- about half of the amount from 1980.

Antarctic glaciers melting faster
Glaciers once held up by a floating ice shelf off Antarctica are now sliding
off into the sea and they are going fast, scientists said Sept.
21. Two separate studies from climate researchers and the space agency
NASA show the glaciers are flowing into Antarcticas Weddell Sea,
freed by the 2002 breakup of the Larsen B ice shelf. Writing in the journal
Geophysical Research Letters, the researchers said their satellite measurements
suggest climate warming can lead to rapid sea level rise.
Many teams of researchers are keeping a close eye on parts of Antarctica
that are steadily melting. Large ice shelves in the Antarctic Peninsula
disintegrated in 1995 and 2002 as a result of climate warming. But these
floating ice shelves did not affect sea level as they melted. Glaciers,
however, are another story. They rest on land and when they slide off
into the water they instantly affect sea level.
It was not clear how the loss of the Larsen B ice shelf would affect nearby
glaciers. But soon after its collapse, researchers saw nearby glaciers
flowing up to eight times faster than before. (Reuters)
Panic erupts in flood-ravaged city
Survivors who were left with almost nothing after Tropical Storm Jeanne
devastated Gonaives, Haiti, buried unclaimed corpses in mud-clogged backyards
and attacked aid trucks and even neighbors bringing them food. Hungry
and thirsty survivors -- some of whom have lost entire families and everything
they own -- were losing patience at the slow pace of relief.
Knee-deep mud sucked up animal carcasses and sharp pieces of torn-off
zinc roofs, as well as human excrement after the sanitation system was
destroyed. Limes have become a hot item in the devastated city of 250,000
because people hold them to their noses to relieve the stench.
This weeks floods were made far worse by massive deforestation that
left surrounding valleys unable to hold the rain unleashed by some 30
hours of pounding by Jeanne.
Health workers feared an outbreak of waterborne diseases, because
of the bodies still in the streets, because people are drinking dirty
water and scores are getting injuries from debris -- huge cuts that are
getting infected, said an aid worker. (AP)
