Public Health Suffers under Factory Farm Sponsored Air Pollution Study
The Center for Food Safety, Environmental Integrity Project, Center on Race, Poverty & the Environment, Sierra Club and others submitted recommendations to the U.S. Environmental Protection Agency (EPA) on June 12, commending its first step towards measuring and regulating air pollution from factory farms, and suggesting improvements to make those measurements more accurate and more protective of public health and quality of life in rural areas.
The draft measurement tools, referred to as “Emissions Estimating Methodologies,” are EPA’s first attempt to estimate the quantities of toxic gases—including ammonia, hydrogen sulfide, particulates and volatile organic compounds—emitted by large livestock operations. EPA based the methodologies on an industry-sponsored study of 21 operations. The factory farm industry proposed the study in 2002, and EPA agreed to grant amnesty from enforcement of clean air laws to nearly 14,000 facilities in exchange for each facility’s contribution to study costs and agreement to participate in the study if selected. This first set of draft methodologies covers emissions from broiler houses and open waste pits at mega-dairy and hog operations.
Environmental Integrity Project Attorney Tarah Heinzen said: “Establishing estimates for factory farm air pollution is a step in the right direction to regulating air emissions to protect public health and the environment. In order to make this a truly effective reform, however, EPA must clarify that all factory farms—not only those that signed up for EPA’s sweetheart deal in 2005—will be required to report emissions estimates and comply with clean air laws without further delay.”
The draft methodologies for the broiler chicken sector indicate that a typical facility with at least 4 chicken houses will exceed the 100 pound per day reporting threshold for ammonia, a requirement that would likely apply to hundreds of facilities in the Chesapeake Bay watershed. In addition to providing data and reducing health impacts, the estimates will help EPA measure and reduce ammonia emissions that re-deposit into waterways—a major source of nitrogen pollution in the Chesapeake Bay and other critical water resources.
Despite the small scale of EPA’s emissions study, the agency has refused to consider other peer-reviewed data. “EPA agreed to consider all relevant information in drafting the EEMs, and it has not,” said Elisabeth Holmes, attorney for the Center for Food Safety. “By neglecting existing, reliable science, the government appears to be willfully ducking documentation that would improve the accuracy and usefulness of its emissions estimates, benefiting public health and the environment. EPA can do better.”
The groups also expressed concern over the complexity of the proposed methods, noting that factory farm operators will have to use the tools and report their own emissions. EPA’s Science Advisory Board established an expert committee to review the highly technical draft methodologies, but the report had not been finalized before the end of public comment. The environmental groups urged EPA to re-open the comment period once this information becomes available.

When Europeans first arrived in North America, Atlantic puffins were common on islands in the Gulf of Maine. But hunters killed many of the birds for food or for feathers to adorn ladies' hats. By the 1800s, the population in Maine had plummeted.

The temperature of the Arctic matters to the entire world: it helps to keep the global climate fairly cool. Scientists now say that by 2035 there could be an end to Arctic sea ice.
Melt Ponds Crucial<p>"The prospect of loss of sea ice by 2035 should really be focusing all our minds on achieving a low-carbon world as soon as humanly feasible."</p><p><a href="http://www.reading.ac.uk/search/search-staff-details.aspx?id=10813" target="_blank">Dr. David Schroeder from the University of Reading</a>, UK, who co-led the implementation of the melt pond scheme in the climate model, says, "This shows just how important sea ice processes like melt ponds are in the Arctic, and why it is crucial that they are incorporated into climate models."</p><p>The extent of the areas <a href="https://nsidc.org/cryosphere/seaice/characteristics/formation.html" target="_blank">sea ice</a> covers varies between summer and winter. If more solar energy is absorbed at the surface, and temperatures rise further, a cycle of warming and melting occurs during summer months.</p><p>When the ice forms, the ocean water beneath becomes saltier and denser than the surrounding ocean. Saltier water sinks and moves along the ocean bottom towards the equator, while warm water from mid-depths to the surface travels from the equator towards the poles.</p><p>Scientists refer to this process as the ocean's global "conveyor-belt." Changes to the volume of sea ice can disrupt normal ocean circulation, with consequences for global climate. </p>

Russia's Health Ministry has given regulatory approval for the world's first COVID-19 vaccine after less than two months of human testing, President Vladimir Putin said on Tuesday.
Putin's Daughter Among Vaccinated<p>The Russian leader also said that one of his daughters has already been inoculated and is feeling well.</p><p>"One of my daughters got vaccinated, so in this sense, she took part in the testing," Putin said.</p><p>After the first vaccine shot, his daughter experienced a slight fever, 38 degrees Celsius (100.4°F). Her temperature came down to just slightly above normal the next day. </p><p>"After the second shot, she had a slight fever again, and then everything was fine. She is feeling well and has a high antibody count," Putin said. </p><p>He didn't specify which of his two daughters, Maria or Katerina, received the vaccine.</p><p>Russian health authorities have said that medical workers, teachers and other risk groups will be the first to receive shots of the vaccine.</p>
Years of Work Reduced to Weeks<p>Russia is the first country to register a COVID-19 vaccine. As <a href="https://www.dw.com/en/germany-coronavirus-vaccine-may-only-be-available-in-mid-2021/a-54362065" target="_blank">countries worldwide race to produce the first vaccine</a>, health experts warn that speed and national pride could compromise safety.</p><p>Scientists in Russia and abroad have questioned Moscow's decision to register the vaccine before Phase 3 trials that normally last for months and involve thousands of people, but Putin emphasized that the vaccine underwent the necessary trials and that vaccination will be voluntary.</p><p>Russian officials have said that large-scale production of the vaccine will begin in September, and mass vaccination may start as early as October.</p><p>Philippine President Rodrigo Duterte, meanwhile, has <a href="https://www.dw.com/en/philippines-duterte-volunteers-to-be-putins-russian-coronavirus-vaccine-guinea-pig/a-54523030" target="_blank">lauded Russia's efforts in developing the vaccine</a> and said that the Philippines is ready to work with Moscow on vaccine trials, supply and production. Duterte volunteered to "be the first they can experiment on."</p><p>"I will tell President Putin that I have huge trust in your studies in combating COVID and I believe that the vaccine that you have produced is really good for humanity," Duterte said, adding that he thinks Russia's vaccine will be ready for the Philippines by December.</p>
