California, Nation’s Top User of Chlorpyrifos, Announces Ban on Brain-Damaging Pesticide
Chlorpyrifos, which is used on almonds, citrus, grapes, cotton, walnuts and other crops, has been shown to harm children's health and neurological development.
"Countless people have suffered as a result of this chemical," California EPA (Cal-EPA) Secretary Jared Blumenfeld told The Guardian. "A lot of people live and work and go to school right next to fields that are being sprayed with chlorpyrifos … It's an issue of environmental health and justice."
“This action represents a historic opportunity for California to develop a new framework for alternative pest manag… https://t.co/vpvqfH5Wlt— California EPA (@California EPA)1557340809.0
The ban will take effect between six months and two years, and is accompanied by $5.7 million in funds from Democratic California Gov. Gavin Newsom to help transition to safer alternatives, The Washington Post reported. California follows Hawaii and New York in approving a ban on the pesticide, and bills to ban chlorpyrifos are being considered by New Jersey, Connecticut and Oregon.
The EPA had recommended banning the pesticide during the Obama administration, but Trump's first pick for EPA Administrator, Scott Pruitt, walked back those efforts in 2017. Environmental groups then sued the agency. In the most recent development in the ensuing legal battle, a federal judge in April ordered the EPA to make a final decision on a ban by mid-July.
"Governor Newsom has done what the Trump administration has refused to do: protect children, farmworkers and millions of others from being exposed to this neurotoxic pesticide," Environmental Working Group President Ken Cook said in a statement reported by The Washington Post. "With the governor's action, California is once again showing leadership in protecting public health."

University of California, San Francisco medical professor and former Cal-EPA Deputy Secretary Dr. Gina Solomon told Time that chlorpyrifos was unique among pesticides in that scientists know a significant amount about how it harms humans.
"We know a lot about what it does to developing children and that science is the bedrock of the action that Cal-EPA is announcing," she said. "Many pesticides have been studied well in lab rats but in this case we actually know what it does to people."
Chlorpyrifos has been shown to harm brain development in fetuses and lead to reduced IQ and reading ability and increased hyperactivity, in children. Children exposed in utero even have smaller heads, Solomon said.
"The science is definitive," Blumenfeld told The Guardian. "This job really should have been done by the US EPA."
However, Solomon noted that since California grows the majority of fruits and vegetables in the U.S., its ban will have a positive impact on other states, too.

One reason activists say the Trump administration has stalled on banning chlorpyrifos is that the predecessor of the pesticide's current manufacturer, DowDuPont, donated to Trump, The Guardian reported. The company has promised to challenge California's ban.
"This proposal disregards a robust database of more than 4,000 studies and reports examining the product in terms of health, safety and the environment," DowDuPont spokesman Gregg Schmidt said in an email reported by The Washington Post. "We are evaluating all options to challenge this proposal."
Chlorpyrifos use has fallen in California from two million pounds in 2005 to 900,000 pounds in 2016, but the state is still the largest user of the pesticide in the U.S.

Trump Calls Fauci 'a Disaster,' Tries to Blame Science and Medical Experts for Failed Coronavirus Response
President Trump attacked the nation's top infectious disease specialist in a call with campaign staffers that several reporters were allowed to listen to on Monday. In the call, Trump said that Dr. Anthony S. Fauci was "a disaster." He added that despite the evidence that coronavirus cases are once again rising across the country, the public was tired of hearing so much news about the virus, especially from "these idiots" in the government and scientific community, as The Washington Post reported.

Colorado voters will decide on Nov. 3 whether the state should reintroduce gray wolves (Canis lupus) after a nearly 80-year absence. Ballot Proposition 114 would require the state to develop and oversee a science-based plan to restore wolves, focused in Western Colorado and initiated by the end of 2023.

Clashing Values<p>Proposition 114 has strong support in Colorado. <a href="https://extension.colostate.edu/topic-areas/people-predators/public-perspectives-on-wolves-and-wolf-reintroduction-8-004/" target="_blank">Statewide surveys </a> conducted by phone, by mail and online over the past two decades have found that 66% to 84% of respondents supported reintroducing wolves. This support is consistent across different regions of the state and diverse demographic groups.</p><p>In a <a href="https://doi.org/10.7717/peerj.9074" target="_blank">survey of Colorado residents</a> that we conducted in 2019, the prospect that wolves could contribute to a balanced ecosystem was the most commonly cited reason for supporting reintroduction. Other arguments included people's cultural and emotional connections to wolves, and <a href="https://extension.colostate.edu/topic-areas/people-predators/moral-arguments-related-to-wolf-restoration-and-management-8-011/" target="_blank" rel="noopener noreferrer">moral arguments</a> that restoring a species humans had eradicated was the right thing to do.</p><p>While overall public support is strong, over half of Colorado's 64 counties have passed <a href="https://www.drovers.com/article/wolf-reintroduction-ballot-colorado" target="_blank" rel="noopener noreferrer">resolutions against restoring wolves</a>. Many ranching and hunting associations are actively campaigning against the ballot measure.</p><p>In our 2019 study, we found that media coverage in the state focused more strongly on <a href="https://doi.org/10.7717/peerj.9074" target="_blank" rel="noopener noreferrer">perceived negative impacts</a> associated with wolf reintroduction than on beneficial effects. Surveys show that resident concerns include threats to <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-and-human-safety-8-003/" target="_blank" rel="noopener noreferrer">human safety and pets</a>; <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-and-livestock-8-010/" target="_blank" rel="noopener noreferrer">wolf attacks on livestock</a>; and the potential for wolves to <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-big-game-and-hunting-8-001/" target="_blank" rel="noopener noreferrer">reduce deer and elk populations</a>, threatening hunting opportunities.</p>
Who Decides?<p>This measure is the first giving voters in the U.S. an opportunity to weigh in on bringing back a native species. Addressing the issue through a ballot measure adds a unique twist to public and media discussions about wolves.</p><p>Supporters call it a democratic way to ensure that the <a href="https://www.cpr.org/2020/09/29/should-wolves-be-brought-back-to-colorado-a-rancher-and-a-biologist-have-their-say/" target="_blank">public's values are recognized</a>.

Finding Consensus<p>Studies suggest that ballot initiatives like 114 will <a href="https://doi.org/10.1016/j.biocon.2017.07.032" target="_blank">become more common</a> as public values toward wildlife change and more diverse groups seek to influence wildlife management.

Fostering dialogue between groups that value wildlife differently can build empathy and mutual understanding and <a href="https://doi.org/10.1016/j.biocon.2014.07.015" target="_blank" rel="noopener noreferrer">foster compromise</a>. Broadening the conversation in this way is essential for coexisting with carnivores with minimal impacts on predators and people.</p>

Fish exposed to endocrine-disrupting compounds pass on health problems to future generations, including deformities, reduced survival, and reproductive problems, according to a new study.
Low Levels Lead to Generational Impacts<p>Researchers exposed inland silverside fish to bifenthrin, levonorgestrel, ethinylestradiol, and trenbolone to levels currently found in waterways.</p><p>"Our concentrations were actually on the low end" of what is found in the wild, DeCourten said, adding that it was low amounts of chemicals in parts per trillion.</p><p>Bifenthrin is a pesticide; levonorgestrel and ethinylestradiol are synthetic hormones used in birth controls; and trenbolone is a synthetic steroid often given to cattle to bulk them up.</p><p>Such endocrine-disruptors have already been linked to a variety of health problems in directly exposed fish including altered growth, reduced survival, lowered egg production, skewed sex ratios, and negative impacts to immune systems. But what remains less clear is how the exposure may impact future generations.</p><p>For their study, DeCourten and colleagues started the exposure when the fish were embryos and continued it for 21 days.</p><p>They then tracked effects on the exposed fish, and the next two generations.</p>
Inherited Problems<p>DeCourten said the altered DNA methylation is one of the plausible ways that future generations would experience health impacts from previous generations' exposure. Hormone-disrupting compounds have been shown to impact DNA methylation, which is an important marker of how an organism will develop.</p><p>"Methyl groups are added to specific sites on the genome, [the exposure] is not changing the genome itself, but rather how the genome is expressed," she said. "And that can be inherited throughout generations."</p><p>In addition, Brander said there are essentially different "tags" that exist on DNA molecules, which tell genes how to turn on and off. She said the exposure to different compounds may be "influencing which methyl tags get taken on or off as you proceed through generations."</p><p>The researchers said the study should prompt future toxics testing to consider impacts on future generations.</p><p>"The results … throw a wrench in the current approach to regulating chemicals, where it's often short-term testing looking at simple things like growth, survival, and maybe gene expression," Brander said.</p><p>"These findings are telling us we really at least need to consider" the next two generations, she added.</p>
