It’s Time to Learn From Frogs

By NICHOLAS D. KRISTOF
Some of the first eerie signs of a potential health catastrophe came as bizarre deformities in water animals, often in their sexual organs.

Frogs, salamanders and other amphibians began to sprout extra legs. In heavily polluted Lake Apopka, one of the largest lakes in Florida, male alligators developed stunted genitals.

In the Potomac watershed near Washington, male smallmouth bass have rapidly transformed into “intersex fish” that display female characteristics. This was discovered only in 2003, but the latest survey found that more than 80 percent of the male smallmouth bass in the Potomac are producing eggs.

Now scientists are connecting the dots with evidence of increasing abnormalities among humans, particularly large increases in numbers of genital deformities among newborn boys. For example, up to 7 percent of boys are now born with undescended testicles, although this often self-corrects over time. And up to 1 percent of boys in the United States are now born with hypospadias, in which the urethra exits the penis improperly, such as at the base rather than the tip.

Apprehension is growing among many scientists that the cause of all this may be a class of chemicals called endocrine disruptors. They are very widely used in agriculture, industry and consumer products. Some also enter the water supply when estrogens in human urine — compounded when a woman is on the pill — pass through sewage systems and then through water treatment plants.

These endocrine disruptors have complex effects on the human body, particularly during fetal development of males.

“A lot of these compounds act as weak estrogen, so that’s why developing males — whether smallmouth bass or humans — tend to be more sensitive,” said Robert Lawrence, a professor of environmental health sciences at the Johns Hopkins Bloomberg School of Public Health. “It’s scary, very scary.”

The scientific case is still far from proven, as chemical companies emphasize, and the uncertainties for humans are vast. But there is accumulating evidence that male sperm count is dropping and that genital abnormalities in newborn boys are increasing. Some studies show correlations between these abnormalities and mothers who have greater exposure to these chemicals during pregnancy, through everything from hair spray to the water they drink.

Endocrine disruptors also affect females. It is now well established that DES, a synthetic estrogen given to many pregnant women from the 1930s to the 1970s to prevent miscarriages, caused abnormalities in the children. They seemed fine at birth, but girls born to those women have been more likely to develop misshaped sexual organs and cancer.

There is also some evidence from both humans and monkeys that endometriosis, a gynecological disorder, is linked to exposure to endocrine disruptors. Researchers also suspect that the disruptors can cause early puberty in girls.

A rush of new research has also tied endocrine disruptors to obesity, insulin resistance and diabetes, in both animals and humans. For example, mice exposed in utero even to low doses of endocrine disruptors appear normal at first but develop excess abdominal body fat as adults.

Among some scientists, there is real apprehension at the new findings — nothing is more terrifying than reading The Journal of Pediatric Urology — but there hasn’t been much public notice or government action.

This month, the Endocrine Society, an organization of scientists specializing in this field, issued a landmark 50-page statement. It should be a wake-up call.

“We present the evidence that endocrine disruptors have effects on male and female reproduction, breast development and cancer, prostate cancer, neuroendocrinology, thyroid, metabolism and obesity, and cardiovascular endocrinology,” the society declared.

“The rise in the incidence in obesity,” it added, “matches the rise in the use and distribution of industrial chemicals that may be playing a role in generation of obesity.”

The Environmental Protection Agency is moving toward screening endocrine disrupting chemicals, but at a glacial pace. For now, these chemicals continue to be widely used in agricultural pesticides and industrial compounds. Everybody is exposed.

“We should be concerned,” said Dr. Ted Schettler of the Science and Environmental Health Network. “This can influence brain development, sperm counts or susceptibility to cancer, even where the animal at birth seems perfectly normal.”

The most notorious example of water pollution occurred in 1969, when the Cuyahoga River in Ohio caught fire and helped shock America into adopting the Clean Water Act. Since then, complacency has taken hold.

Those deformed frogs and intersex fish — not to mention the growing number of deformities in newborn boys — should jolt us once again.

State leads the way in climate-change rules
David R. Baker,Matthew B. Stannard, Chronicle Staff Writers

Sunday, June 28, 2009

When California passed sweeping laws to fight global warming nearly three years ago, Gov. Arnold Schwarzenegger and other state politicians hoped the move would force a reluctant federal government to act.
They got their wish.

The landmark climate-change bill approved Friday by the House of Representatives copies whole chapters from California's global warming playbook. Its limits on greenhouse gas emissions are similar to those in the state. So is the method for cutting emissions, a complex system called cap and trade.

In addition, the bill's emphasis on energy efficiency, especially in new buildings, is pure California, and its limits on new coal-burning power plants parallel California's.

"California's fingerprints are all over it," said Carl Zichella, regional director for the Sierra Club. "You look at the major components of this legislation and you see the leadership California has provided over the last eight years."

It's no accident. Los Angeles Democratic Rep. Henry Waxman co-wrote the bill. San Francisco's Nancy Pelosi, the House speaker, corralled the votes to pass it. Rep. Mary Bono Mack of Palm Springs was one of only eight Republicans to vote for the bill, sealing its victory.

"I'm sure she's been under a lot of pressure," her fellow Energy and Commerce Committee member, Rep. Jerry McNerney, D-Pleasanton, said after the vote. "(But) she has a lot of new energy technology in her district, and she understands where that can create jobs."

Critical role
McNerney, whose background is in generating wind energy, said the California congressional delegation played a critical role in the passage of the bill.

"I wouldn't want to say we were setting the agenda; we're offering a lot of leadership and doing a lot of the heavy lifting," he said. "We wouldn't have gotten this done without the delegation."

The California connection hasn't been lost on the bill's opponents, either.

"As goes California, so goes the nation," warned an editorial from the conservative Competitive Enterprise Institute. "Nowhere is this adage truer than in environmental policy, thanks to Democrats' eagerness to impose the Golden State's radical eco-agenda on all Americans."

California isn't the only state with global warming programs. Many states, tired of waiting for federal action, have drafted policies to cut carbon dioxide emissions, although California was the first to write that goal into law.

Twenty-four states are developing cap-and-trade systems, most of them working in regional blocks that cover the West, the Midwest and the Northeast. The House bill's other lead author, Rep. Ed Markey, hails from Massachusetts.

Renewable power
Two dozen states also require their utilities to use more renewable power, setting minimum limits that electric utilities must meet or beat by specific dates. California law, for example, requires all utilities to get 20 percent of their power from renewable sources by the end of 2010.

That's the toughest such standard in the nation, illustrating another reason the federal legislation takes cues from California. In general, California has adopted regulations on greenhouse gases, renewable power and energy efficiency faster than the rest of the nation and the rules here tend to be tougher than they are elsewhere.

"We've set the highest standards, we've had the most aggressive program and we've blazed the way," Zichella said.

Many Californians who have pushed hard for federal legislation on climate change worry that the House bill is too weak. But Peter Darbee, chief executive officer of Pacific Gas and Electric Co., said the system it would create to cut greenhouse gas emissions could be honed and improved once it wins approval.

"My own view is that we need to get a basic platform in place, and it's important we do so sooner rather than later," said Darbee, who spent part of last week in Washington lobbying for the House bill. "Then when we have it in place, we can see how it works. We may see that it performs exactly as projected, which most things don't."

Suspending some programs
If the House bill, called the American Clean Energy and Security Act, survives the Senate, it would suspend some of the state climate-change programs but leave most of them running.

For example, the bill would set a minimum requirement for the renewable power each state must use - about 15 percent by the year 2020. But states with more stringent standards, such as California, would be able to enforce their higher limits.

"It doesn't say, 'Oh, California should dial back,' " said Energy Secretary Steven Chu, the former head of Lawrence Berkeley National Laboratory. "It certainly will not trump the more aggressive (states)."

There is one key exception. The bill would suspend for five years all state-run cap-and-trade systems. Cap-and-trade systems set a declining limit on greenhouse gas emissions and then force companies to buy and sell credits to emit specific amounts of gas.

California plans to start a cap-and-trade system in 2012, creating a carbon dioxide market that would include six other Western states and four Canadian provinces. Mary Nichols, head of the California agency charged with creating the market, said the state would push forward despite the federal bill. That way, California and its neighbors may be able to influence the rules of the proposed federal carbon market.

"For the time being, it's extremely important for all concerned that we continue to work on these issues because we've already seen how much our willingness to get out there and address these issues has benefited the nation as a whole," said Nichols, who chairs the California Air Resources Board.

Different goals
As outlined in the House bill, the federal cap-and-trade system would cut greenhouse gas emissions 17 percent from 2005's levels by the year 2020, while California's proposed system would cut roughly 15 percent. By 2050, the federal system would slash emissions more than 80 percent, compared with 83 percent under California's system.

There are other similarities. The House bill would require new buildings to be 30 percent more energy-efficient in 2012 and 50 percent more efficient by 2016. California has set, and continuously tightened, energy-efficiency standards for new buildings since the 1970s.

Under the federal plan, strict emission limits would be placed on new power plants burning coal. By 2020, all new coal plants would have to cut greenhouse gas emissions by 65 percent. From now to 2020, new coal plants would have to slash their emissions by 50 percent. Coal plants would not be able to comply with such limits without capturing emissions and storing them underground, experts say.

Stricter rules
California, by comparison, simply forbids new coal plants unless they reduce their greenhouse gas emissions to the level of a power plant burning natural gas.

Perhaps most critically, the House bill would not prevent states from exploring other ways to fight climate change, allowing them to continue innovating.

"This is the bright spot ... this bill does not take away their authority to impose regulations or policies to reduce greenhouse gas emissions," said Danielle Fugere, Western Regional Program Director of Friends of the Earth, an environmental group that opposed the bill as too weak. "You'll see continued motion in the East Coast and the West Coast."
