Fracking Linked to Cancer-Causing Chemicals, Yale Study Finds
Yet another study has determined that hydraulic fracturing, or fracking, might be a major public health threat. In one of the most exhaustive reviews to date, researchers from the Yale School of Public Health have confirmed that many of the chemicals involved and released by the controversial drilling process can be linked to cancer.

"Previous studies have examined the carcinogenicity of more selective lists of chemicals," lead author Nicole Deziel, Ph.D., assistant professor explained to the school. "To our knowledge, our analysis represents the most expansive review of carcinogenicity of hydraulic fracturing-related chemicals in the published literature."
For the study, published in Science of the Total Environment, the researchers assessed the carcinogenicity of 1,177 water pollutants and 143 air pollutants released by the fracking process and from fracking wastewater. They found that 55 unique chemicals could be classified as known, probable or possible human carcinogens. They also specifically identified 20 compounds that had evidence of leukemia/lymphoma risk.
One of the scarier parts from this study is that the researchers could not completely unpack the health hazards of fracking's entire chemical cocktail. More than 80 percent of the chemicals lacked sufficient data on cancer-causing potential, "highlighting an important knowledge gap," the school noted.
The unconventional drilling rush in the U.S. has expanded to as many as 30 states, spelling major consequences to the air we breathe and the water we drink. The Wall Street Journal reported in 2013 that more than 15 million Americans lived within a mile of a well.
The biggest concern is for people and especially children with fracking operations right in their backyards. In fact, Environment America found that more than 650,000 kindergarten through 12th grade children in nine states attend school within one mile of a fracked oil or gas well.
“Because children are a particularly vulnerable population, research efforts should first be directed toward investigating whether exposure to hydraulic fracturing is associated with an increased risk," Deziel said.
Per the study, "Childhood leukemia in particular is a public health concern related to [unconventional oil and gas] development, and it may be an early indicator of exposure to environmental carcinogens due to the relatively short disease latency and vulnerability of the exposed population."
According to the school, the researchers are now taking air and water samples in a community living near a fracking operation. They are testing for the presence of known and suspected carcinogens and will determine whether these people have been exposed to these compounds, and if so, at what concentrations.
Monsanto, the maker of the glyphosate-based herbicide Roundup, filed a motion June 16 in U.S. District Court, Northern District of California to reconsider the chemical's addition to California's Proposition 65 list of agents known to cause cancer.
The agrochemical giant made this move based on a June 14 Reuters investigation of Dr. Aaron Blair, a lead researcher on the World Health Organization's International Agency for Research on Cancer (IARC) committee, that classified glyphosate as a "2A probable human carcinogen" in March 2015.

Algae is often considered a nuisance, but for Sweden, the rapidly growing sea plant is now an asset.
As the Scandinavian country works to cut all of its greenhouse gas emissions by 2045, it's using algae to sop up the carbon emissions from cement.

A recent intensification in protests against Williams Partners' planned Atlantic Sunrise pipeline in Pennsylvania prompted a state senator to propose legislation aimed at limiting demonstrations.
Last month, Pennsylvania Sen. Scott Martin (R-Norman) announced his intention to introduce legislation that would pass the costs of law enforcement responding to protests onto the demonstrators. Martin also helped introduce a different bill that would criminalize protests at natural gas facilities.
The so-called "first and last mile" problem is one of the biggest hurdles with public transportation. How do you encourage more people to take Earth-friendlier commutes when their homes are miles away from the train or bus station?
One solution, as this Estonian electric scooter company proposes, is to simply take your commute with you—literally. Tallinn-based Stigo has developed a compact e-scooter that folds to the size of a rolling suitcase in about two seconds.
[Editor's note: I'm still in shock after hearing the news that Lucia Grenna passed away in her sleep last week. When we first met in April of 2014 at a Copenhagen hotel, I was immediately taken by here powerful presence. We spent the next couple days participating in a Sustainia climate change event where Lucia presented her audacious plans to connect people to the climate issue. I had the chance to partner with Lucia on several other projects throughout the years and work with her incredible Connect4Climate team. I was always in awe of her ability to "make the impossible possible." Her spirit will live on forever. — Stefanie Spear]
It is with a heavy heart that Connect4Climate announces the passing of its founder and leading light, Lucia Grenna. Lucia passed peacefully in her sleep on June 15, well before her time. We remember her for her leadership and extraordinary ability to motivate people to take on some of the greatest challenges of our time, not least climate change.

Neil deGrasse Tyson has inspired millions of people to care about science and imagine themselves as participants in the scientific process. What a hopeful sign it is to see young girls wearing t-shirts emblazoned with the words, "Forget princess, I want to be an astrophysicist."
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."
