With supermarket milk cheaper than spring water, it's time to rethink the modern dairy industry. It's not just the milk that's become a throwaway product - the high-octane Holstein cows that produce it are also in the knackers yard after just two or three lactations, the living waste of a loss-making, environment-trashing industry.

Sandy Oliviera has raised monarch butterflies in her East Providence backyard for 25 years. In 1998, she helped 125 monarch caterpillars transform into butterflies, and then released them to the wind.
"I began to feel like a butterfly factory that year," Oliviera said. Each time her husband or daughter collected milkweed to feed their captive caterpillars, they returned with more eggs or caterpillars to raise. Some days, Oliviera released a dozen newly emerged butterflies, to the pleasure of her 8-year-old grandson who let them rest on his head before they flew away.
This summer, for the first time, Oliviera hasn't found a single monarch egg or caterpillar, and hasn't seen any monarch butterflies.

Deepwater Wind has received the final federal approval needed to build the Block Island Wind Farm — a project that remains on-track to be the nation’s first offshore wind farm.
The project’s lead federal permitting agency, the Army Corps of Engineers, granted its approval Sept. 5. With the Corps’ permit, the Block Island Wind Farm has now been completely reviewed, and approved, by nine state and federal agencies: Army Corps of Engineers, Federal Aviation Administration, U.S. Fish & Wildlife Service, National Oceanic and Atmospheric Administration, Environmental Protection Agency, Coast Guard, Rhode Island Coastal Resources Management Council, Rhode Island Department of Environmental Management and the Rhode Island State Historic Preservation Office.

The food chain is a hierarchical series of organisms that are interrelated in their feeding habits. The chain starts when the smallest being like an insect is fed upon a larger prey species, which in turn feeds an even larger species. So if a species among the lower ranks of the chain has accumulated toxins such as pesticides or other organic chemicals, there is potential for these toxic substances to affect the species that prey upon them. This is the subject of new research conducted by the US Geological survey that found when fish feed on insects and when other wildlife species feed on fish, harmful contaminants are transferred up the line.

Residential geography, time spent in the sun, and whether or not sunglasses are worn may help explain why some people develop exfoliation syndrome (XFS), an eye condition that is a leading cause of secondary open-angle glaucoma and can lead to an increased risk of cataract and cataract surgery complications, according to a study published on Sept. 4 in JAMA, Ophthalmology.
Despite improvements in understanding the cause of this common yet life-altering condition, more work needs to be done. "The discovery that common genetic variants in the lysyl oxidase-like 1 gene (LOXL1) are associated with 99 percent of XFS cases represented a significant advance in our understanding of this condition," said the study's lead author, Louis Pasquale, M.D., Associate Professor of Ophthalmology at Harvard Medical School (HMS), and director of the HMS Glaucoma Center of Excellence and Mass. Eye and Ear Glaucoma Service and Telemedicine Service. "However, 80 percent of control individuals also harbor these variants and that ratio of cases to control individuals with trait-related variants is fairly similar in regions where XFS is very prevalent and in regions where the condition is relatively rare; this suggests that other genetic or environmental factors contribute to XFS."

The International Seabed Authority (ISA) has begun issuing exploration licenses for mining the yet untouched floor of international waters raising concerns about potential environmental impacts. The licenses, issued on 21 July, grant prospecting rights for underwater minerals to private and state-owned companies from Brazil, Cook Islands, Germany, India, Russia, Singapore and the United Kingdom.

In one year, India's ozone pollution damaged millions of tons of the country's major crops, causing losses of more than a billion dollars and destroying enough food to feed tens of millions of people living below the poverty line. These are findings of a new study that looked at the agricultural effects in 2005 of high concentrations of ground-level ozone, a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. Able to acquire accurate crop production data for 2005, the study's authors chose it as a year representative of the effects of ozone damage over the first decade of the 21st century.

Mothers who live in neighborhoods with plenty of grass, trees or other green vegetation are more likely to deliver at full term and their babies are born at higher weights, compared to mothers who live in urban areas that aren’t as green, a new study shows.
The findings held up even when results were adjusted for factors such as neighborhood income, exposure to air pollution, noise, and neighborhood walkability, according to researchers at Oregon State University and the University of British Columbia.

How can a manufacturer reformulate a cleaning product to contain fewer harmful chemicals, and how can a retailer stock its shelves with more eco-friendly merchandise? UL (Underwriters Laboratories), a product safety testing and certification company, thinks it may have a solution: a set of data tools that helps businesses search and choose ingredients and products based on their environmental and social responsibility profiles.
