The Fall of the MammalsOctober 14, 2008Reporting by Roddy Scheer
“More than simply reporting on the depressing status of the world's mammals, these … data can and should be used to inform strategies for addressing this crisis, for example to identify priority species and areas for conservation,” the researchers concluded. "Despite a general deterioration in the status of mammals, our data also show that species recoveries are possible through targeted conservation efforts." “I think the bottom line is, what kind of a world do you want to leave for your children?," said Arizona State University life sciences professor Andrew Smith, one of researchers who contributed to the report which culled data from some 1,700 experts across 130 countries. “How impoverished we would be if we lost 25 percent of the world's mammals.” Source: IUCN |

Ted Turner’s New Travel RulesOctober 14, 2008Reporting by Roddy Scheer
Available for free at www.SustainableTourismCriteria.org, these guidelines focus on four critical aspects: maximizing tourism's social and economic benefits to local communities; reducing negative impacts on cultural heritage; reducing harm to local environments; and planning for sustainability. “Sustainability is just like the old business adage: “You don't encroach on the principal, you live off the interest',” says Turner. "Unfortunately, up to this point, the travel industry and tourists haven't had a common framework to let them know if they're really living up to that maxim. But the Global Sustainable Tourism Criteria (GSTC) will change that. This is a win-win initiative—good for the environment and good for the world's tourism industry." |

COMMENTARY: Changing Direction on Lead RulesWhen It Comes to Lead, The EPA Needs New AnswersBy Tim LaFond The Environmental Protection Agency (EPA) will issue new lead emissions regulations by October 15. EPA’s proposed regulations would tighten the National Ambient Air Quality Standard for lead. Driving EPA’s push for stricter regulations is the agency’s growing concern about the effect of lead exposure on children. We know the most at-risk children are those living in areas where 60% of the population lives in poverty.
EPA’s final rule must protect the most at-risk children from lead poisoning. These children live in major cities and high-poverty areas where the danger from lead poisoning comes from deteriorating lead paint, lead-contaminated dust and lead-contaminated soil, including soil still contaminated by the now-banned lead gasoline. EPA must implement a greatly expanded and more targeted air lead monitoring program in those cities and poor areas where the most at-risk children live. Unfortunately, EPA’s proposal will not accomplish this task. EPA emphasizes the monitoring of industrial facilities—no longer the major source of lead emissions—and requires only a small network of monitors in urban areas. Given its proposed monitoring requirements, EPA may be unable to collect the basic data needed to attack lead pollution. For example, EPA would require only a single monitor in Michigan, two in Illinois and three in New York. More monitors are needed for EPA to address children’s health concerns. States could comply with EPA’s proposed requirements by putting a single monitor in each city with one million or more people, a total of 50 population-based monitors in urban areas across the entire country. No monitors would be required in the highest risk areas where more than 60% of children live in poverty and only a handful of monitors would be located in areas where more than 25% of the children are poor. Yet children in these counties are the ones most at-risk of lead poisoning. A monitoring network aimed at protecting the most vulnerable children demands more monitors in cities and many more monitors in high-poverty areas where a disproportionate number of African American and Hispanic children live. EPA also must place these monitors in urban areas, not suburbs, preferably in locations as close to children’s activities as possible. Too often, the monitors have been placed on rooftops or along paved residential areas in newly developed neighborhoods, not near playgrounds, sports facilities and roadways or housing areas where lead paint is a problem. These monitors must be roughly placed at the height of a child. Let me be clear: I am not recommending that the monitoring of industrial facilities be stopped. If factory emissions are not properly contained, EPA monitoring makes sense. But most industrial facilities have been appropriately regulated for three decades. Tough emissions standards for these plants are justified and the lead industry will comply with EPA requirements. But industry compliance alone will not allow EPA to meet its goal. EPA should be proud of its success in reducing lead emissions and improving children’s health. Over the last 30 years, government and industry effort to reduce lead emissions ranks as one of the nation’s great environmental success stories. Air lead levels have dropped 98% since 1978, with lead emissions decreasing from 74,000 tons annually three decades ago to 1,300 tons a year. Most important of all, blood-lead levels in children have plummeted—from a mean level of over 14 micrograms per decaliter in 1976 to well less than two today. But just tinkering with the same old approach is not enough. EPA must employ new tactics to reduce lead poisoning. The new regulations must protect the most at-risk children. EPA should adopt a greatly expanded and highly targeted monitoring system in urban areas and those pockets of poverty where at-risk children live. Increased monitoring will give EPA the tools needed to reduce lead poisoning in children.

Presidential Science LessonsThe Next President Faces Tough Decisions in Science and PolicyBy Josh McDaniel Early in the administration of the next president, the first synthetic organism—a bacteria-like creature—is due for production in the United States. When that happens, the president, the U.S. public and the world will be dealing with the first in a series of scientific, ethical and policy concerns that will come to the forefront in the next few years. Other challenges will follow in the fields of nanotechnology and genetics. How do we harness the benefits of scientific exploration into the very nature of life without crossing moral lines? How do we promote manipulation of matter at the atomic and molecular level while regulating the potential hazards?
Presidential Power The president’s role in providing direction to research is immense. The executive branch controls a $150 billion research budget and entire research programs can hinge on support from the Oval Office. President Bush’s refusal to fund research on stem cells, for example, has caused the U.S. to fall far behind programs in Europe, China and elsewhere. The executive branch also has 200,000 federal scientists working in the Environmental Protection Agency (EPA), the Food and Drug Administration, Centers for Disease Control, the Fish and Wildlife Service and other agencies, and controls 38 major research institutions. The scientific stakes are high, especially as the world enters a new technological era defined by synthetic biology, genetics and nanotechnology. Nations are already jockeying for position to secure the commercial, military and societal gains from these fields. Scientists are working to create customized organisms and minute technology that could manufacture and deliver drugs, clean up pollution and cheaply and efficiently produce biofuels like ethanol, and the potential benefits are huge. The risks are also enormous. Military applications could lead to a new arms race as miniaturized and biological weapons become more readily available. Artificial life forms created for more benign purposes could behave unpredictably or mutate, leading to new health and environmental threats. There is concern that carbon nanotubes, already commercially available to reinforce plastic materials, can affect the lungs in ways similar to asbestos. And an avalanche of nanoproducts will be released in the coming years. At present, there is little government oversight of work in nanotechnology and synthetic biology, and the labs themselves provide the only safety checks. Regulations that do exist were drawn up years before these industries developed and do not apply to the specific challenges they present. Critics worry that it will only be a matter of time before a synthetic life form is released and runs amok or a disaster at a nanotechnology plant creates a major health crisis. The President will have to take the lead in creating the proper regulatory environment for these technologies. This means promoting research into the environmental and health impacts of the manufactured products and health services that are rapidly entering the marketplace. The President will also guide the nation through the moral and legal questions surrounding areas such as genetic discrimination and genetic patenting. This will take real leadership: the active engagement of a president with the best available information and scientific advisors. Restoring Science in Washington It is no secret that the scientific community has been at odds with the Bush administration. Reports of oil industry lobbyists rewriting scientific reports on climate change, and political appointees in the Fish and Wildlife Service bullying scientists on reports related to endangered species listings have been well publicized. A number of books such as The Republican War on Science by Chris Mooney (Basic Books) and The Assault on Reason by Al Gore (Penguin) have pointed to an unprecedented White House-directed effort to distort and suppress science on issues ranging from lead poisoning and mercury pollution to the effectiveness of condoms in preventing HIV/AIDS.
“The most important thing we need is leadership,” says Grifo. “Science is not always the primary factor in any decision, but you need to say, ‘The science says one thing on the topic, but for these other reasons, we have decided to choose this other path.’ Over and over again, this administration has chosen instead to manipulate the science to an endpoint that is palatable to them.” Mooney, who is a contributing editor to Science Progress and blogs on science issues at The Intersection (www.scienceblogs.com/intersection), was one of the organizers of Science Debate 2008. He says the idea was not to spring a pop quiz on candidates about the periodic table or the functions of the mitochondria, but to get them to discuss some of the big issues like climate change, research funding priorities, and the connection between science education and U.S. competitiveness. “There has been so little discussion of science during the campaign—that is why this is so important,” Mooney says. “We wouldn’t have to do this if the media had made it a priority.” He has a point. There have been very few questions directly related to science during the primary debates or in TV news interviews. The League of Conservation Voters analyzed the transcripts of the major debates and interviews and found that out of 3,302 questions asked of the candidates, only eight of them mentioned global warming. The most significant discussion of science and policy occurred during the Compassion Forum at Pennsylvania’s Messiah College. Democratic candidates Hillary Clinton and Barack Obama were asked to explain how they related their faith and personal convictions to issues of science, stem cell research and climate change policy. Given the setting and the audience, the answers were understandably weighted more towards the senators’ personal ideology than the intricacies of climate modeling. While climate change is the science issue that receives the most attention in the press, it routinely fails to crack the top 10 issues covered by the media in the Pew Media Index, a weekly analysis of news coverage. According to Pew, the height of media interest in climate change occurred in the first few months of 2007 after the release of An Inconvenient Truth on DVD and the publication of a report from the Intergovernmental Panel on Climate Change, which showed that humans were almost certainly causing global warming, that sea levels were likely to rise and Arctic summer sea ice is likely to disappear in the second half of the century. Still, climate change made up only 5% of the news coverage as compared to tensions with Iran (13%), the presidential campaigns (11%), and the Iraq War (9%). Matthew Nisbett, a professor of communications at American University, says that there is a complex cycle of reinforcement between the public and the media. If the media doesn’t put climate change or science on the agenda, he says, the public is unlikely to see it as a priority, either. Nisbett says climate change actually ranks in the third tier of key issues in polling. “The media looks at the polls and climate change is just not showing up,” he says. “And the candidates are looking at those same polls.” A recent Pew study of policy issue priorities found that climate change ranked 15th out of 20 issues for Democrats, right between the need for middle class tax relief and the decline in morality. For Republicans, climate change ranked 20th out of 20 issues, far behind insuring the uninsured, which placed 19th. The Science Debate 2008 organizers were fighting an uphill battle from the start. Even those within the science community had their doubts about the debate’s merits. Critics argued that it might further politicize science as viewers chose positions based on their party or personal alignment with certain candidates. And scientists feared they might lose control of the message as politicians and media pundits applied their own interpretations to research results. Dr. Sheila Jasanoff, a professor of science and public policy at Harvard University’s John F. Kennedy School of Government, has been observing and writing about the interplay between science and democracy for 30 years. “Science has not always been a political issue,” she says. “In the 1950s and ’60s it was never an issue—even through the 1970s and early ’80s. The only reason it is part of the current political constellation now is because it is so lacking in the current administration.” A New Beginning “Bush is the easiest act to follow in American political history,” says Green Party presidential candidate and consumer advocate Ralph Nader. Nader has long fought for strengthening the role of science in policy-making, and his efforts have been instrumental in the establishment of the Occupational Safety and Health Administration, the EPA, the Consumer Product Safety Commission and the Safe Drinking Water Act. He says he is now seriously concerned about the lack of regulatory oversight in both biotech and nanotech.
The major party candidates appear to be listening. Democratic nominee Barack Obama often cites the role of science and technological innovation in driving the U.S. economy. Jason Grumet, Obama’s climate change advisor, told E, “Senator Obama believes that there is a fundamental need for transparency in government. He does not believe that you can answer political questions solely with science, but there has to be clarity and integrity in how science is used in the political process.” Grumet says that the campaign has created a science policy group to search out ways to elevate the role of science in government. Some of the ideas under development include setting conflict-of-interest rules for scientific advisory boards, ensuring that political appointees in positions with research mandates have proper scientific credentials, and creating a new scientific advisory group for the president. And John McCain, the Republican nominee, has also signaled a break from the Bush administration’s approach to environmental issues. In a May 2008 speech on climate change, Senator McCain said, “I will not permit eight long years to pass without serious action on serious challenges. The United States will lead, and it will lead with a different approach.” Douglas Holtz-Eakin, a Senior Policy Advisor to McCain, told E that one of McCain’s primary goals was “to stop the demagoguery of the science of climate change in the place of real debates. He believes the president is the one who will set the tone of that debate.” Holtz-Eakin also said that McCain views the restoration of science in the policy process as fundamental to restoring faith in the government mission. “He believes that we need to reform government to be responsive—maintaining infrastructure, keeping people safe, encouraging civil society—not just being an election machine in D.C.” The antipathy to science that has characterized the past eight years looks to be coming to an end. “I am absolutely optimistic that this can be turned around with the right leadership,” says Grifo. “This is absolutely solvable.” Jasanoff points out that the U.S. has the deepest turnover in bureaucracy of any western society. Most of the political appointees who have been working against science will be looking for new jobs this coming January. She believes that the Bush years will be seen as an aberration, with a return to a much more stable relationship between the executive branch and the scientific community no matter who the next president is. But a return to the status quo won’t be enough. The new president will be faced with scientific breakthroughs that require a much deeper engagement with science. And if efforts to curb CO2 emissions prove to be too little, too late, adaptation to climate change may require risky and controversial large-scale geoengineering projects. Proposals range from building massive seawalls to dumping iron into the oceans to encourage the growth of plankton and the absorption of CO2. These are complex questions that dwarf debates over stem cell research and the causes of climate change. The incoming president will play a primary role in guiding the public through that process, deciding on the proper role of government and negotiating the divisive dance between science and religion that has come to characterize public discussion of these issues. But mostly it will be the next president’s task to inspire the country to look to science in facing our biggest challenges. Mooney has argued that the currents are in place for a science revival in U.S. public dialogue—one that could “alter the very zeitgeist of the nation, and even that of the world.” The selection of the next president, and that person’s engagement and interest in science, will play a critical role. Our standing in the world, and the health of that world, may well depend on it. JOSH MCDANIEL is an environmental writer living in Colorado.

Chasing the ChestnutBy Brian ColleranEfforts to save the American chestnut go beyond ecology. “We’ve lost the American elm and the flowering dogwood, yet all this effort is going into this one particular species,” says Dr. Brian McCarthy, the secretary of The American Chestnut Foundation’s (TACF’s) Ohio chapter, and a professor at Ohio University. “Chestnuts are one of the symbols of this country, right up there with Mom and apple pie, and losing the species would be like losing a part of American history.”
At the State University of New York’s School of Environmental Science and Forestry (SUNY-ESF), Dr. William Powell’s lab is investigating the genes that offer resistance to the chestnut blight. His group has also genetically engineered blight-resistant American chestnuts using a gene that comes from wheat. Their research may lead to blight-resistant chestnut trees being planted in as little as five years. Not all efforts to save the chestnut rely on importing new genes into the species. The American Chestnut Cooperators Foundation (ACCF) is working with Virginia Tech and Concord College researchers to find native chestnut trees showing some blight resistance and breeding those individuals. The results are still being evaluated, but the effort is important to those who wish to maintain a genetically pure strain of the species. “With climate change, we really need to keep as many species as possible,” says Dr. Bob Grese of the University of Michigan’s School of Natural Resources and the Environment. “Even if the trees aren’t 100% genetically pure American chestnuts, we need to keep what we can, and not let the American chestnut slip away.” CONTACTS: American Chestnut Cooperators Foundation; The American Chestnut Foundation; American Chestnut Research and Restoration Project
