LED Lighting Could Have Major Impact On Wildlife

LED Lighting Could Have Major Impact On Wildlife

Environment, Latest News
LED street lighting can be tailored to reduce its impacts on the environment, according to new research by the University of Exeter. The UK-based study found predatory spiders and beetles were drawn to grassland patches lit by LED lighting at night, but the number of species affected was markedly reduced when the lights were dimmed by 50% and switched off between midnight and 4am. LEDs made up just 9% of the global lighting market in 2011, but forecasts suggest they will account for 69% by 2020. This has led to concerns about their effects on plants and animals, and the Exeter scientists say research is urgently needed to understand how best to prevent unforeseen ecological effects. "We are making fundamental changes to the way we light the night-time environment, with potent...
Plan To Reduce Air Pollution Chokes In Mexico City

Plan To Reduce Air Pollution Chokes In Mexico City

Environment, Latest News
Decades ago Mexico City's air quality was so poor, birds would fall out of the sky -- dead. Locals said living there was like smoking two packs of cigarettes a day, according to one report. In response, Mexico City took several steps to try to improve air quality including restricting driving one or two days during the weekdays. The program has had negligible results. In 2008, the city added driving restrictions on Saturdays in hopes of moving the needle but according to new research by Lucas W. Davis, an associate professor at UC Berkeley's Haas School of Business, extending the program one more day also isn't working. "Saturday driving restrictions are a flawed policy. It's a big hassle for people and does not improve air quality," says Davis, who is also the faculty director at ...

On Aug. 21, a total solar eclipse will be visible from the United States for the first time since 1979. Sky watchers in North America and Hawaii will be able to see at least a partial solar eclipse on that summer day, but most people will have to travel to see the sun completely eclipsed by the moon. If you're considering making a trip to see the total solar eclipse, here's a guide to which states and cities fall inside the path. On that third Monday in August, the sun will appear to be partially obscured by the moon to viewers across all of North America and in Hawaii. Just how much of the sun will be eclipsed by the moon will depend on where you're observing from. For most people in the U.S., the moon will appear to cover at least two-thirds of the sun and in many locations it will...

PWSA issues boil water advisory for eastern and central Pittsburgh

Environment, Health, Latest News
An estimated 100,000 Pittsburgh residents throughout eastern sections of the city were left without safe tap water on Tuesday night. PWSA released a statement on their website saying recent tests of the water at the Highland Park water filtration plant revealed low levels of chlorine. Since chlorine is typically used to disinfect Pittsburgh water, PWSA instructed locals to take precautionary measures until further notice. PWSA also said the lack of chlorine could cause an increase in digestive upset, vomiting and headaches, as well as other ailments. Schools in the affected areas are closed until tomorrow. PWSA is notifying the public out of an abundance of caution, and there is no evidence of any bacteria in the system. There is no direct evidence that PWSA’s water is unsafe, but the a

US President Donald Trump's administration has instructed the Environmental Protection Agency to remove the climate change page from its website. It is latest move by the new leadership to erase former president Barack Obama's climate change initiatives. The employees were notified by EPA officials yesterday that the administration had instructed EPA's communications team to remove the website's climate change page, which contains links to scientific global warming research, as well as detailed data on emissions. The page could go down as early as today, the sources said. "If the website goes dark, years of work we have done on climate change will disappear," one of the EPA staffers told Reuters. They said that some employees were scrambling to save some of the information...
