Comments Off on Air pollution may decrease eggs in women’s ovaries

Air pollution doesn’t only affect your lungs as new research suggests air quality may also be linked to a decrease in the number of eggs in women’s ovaries. It has long been known that environmental factors impact our reproductive systems, and multiple studies linked low sperm count with environmental indicators, but fewer examine the connection to ovaries. This newest study, presented at the European Society of Human Reproduction and Embryology is the first to look at the prevalence of eggs and not just fertility. Italian researchers collected hormone samples from 1,300 Italian women and compared their levels of the AMH hormone to air quality metrics. The AMH hormone typically signals a woman’s egg “reserves” but can also fluctuate depending on the woman’s age, genetics and if they are a smoker. Related: Almost all U.S. national parks have polluted air Researchers found that lower AMH hormone levels were associated with higher air pollution indices. This suggests that air pollution may be connected to lower egg count in ovaries. However, researchers also recognize that often air pollution is concentrated in areas with lower income and other environmental justice issues, therefore there are likely confounding factors that also impact women’s ovaries within these areas. The study also did not measure direct exposure to air pollution, only indirect exposure via the average air pollution index at the participants’ home address. “Living in an area associated with high levels of air pollutants in our study increased the risk of severely reduced ovarian reserve by a factor of two or three,” said Dr. Antonio La Marca, who led the research. Other studies have similarly linked air quality with womens’ reproductive health, including one study that links pollution with irregular menstrual cycles and another that connected ozone pollution with decreased fertility . More research is needed to clarify the findings and determine if this is a temporary or permanent effect for women. Via The Guardian Image via Ian MacNicol

Sustainably-sourced sunglasses built to last a lifetime rather than a season

Comments Off on Sustainably-sourced sunglasses built to last a lifetime rather than a season

Living a sustainable lifestyle is about more than backyard composting and prolific use of Mason jars in lieu of plastic. To truly reach any level of sustainability we need to be aware of every purchase we make including how the product was made and even the packaging used. Although our conscientious purchasing decisions carry weight, corporate responsibility is where the real change will occur — enter Just Human. Just Human feels the burden of that responsibility and has decided to do something about it in the form of long-lasting, quality sunglasses built to last a lifetime, not a season. Related: These sustainable sunglasses smell like coffee and decompose into fertilizer The creation of the sunglasses released earlier this year began with four principals: Focus on the entire system of product creation, from materials to manufacturing to packaging. Streamline the design so that there are only a few products in production, each with a unisex design to serve as many people as possible. Combine function and fashion with a high-performing lens. Focus on durability for a product that won’t end up in the landfill anytime soon. Rather than relying on cheap synthetic materials that have become mainstream in the industry, Just Human sources material for the frames from softwood trees that are sustainably harvested and have earned FSC certification. The glass lenses are made from sand and minerals instead of petroleum-based plastic. Even the cutoffs from lens production are recycled and used for the next round of lens material. Pineapple leaf fibers (we’re hearing a lot about these lately!) and recycled water bottles make up the material for the case that house the sunglasses. The included cleaning cloth is produced using fabric made from 2.5 plastic water bottles . Carrying the eco-friendly idea through to the packaging, Just Human uses 100 percent post-consumer cardboard, eco-friendly inks and compostable tape made from wood pulp. Just Human understands that a focus on sustainability is a mute point if the product doesn’t meet the needs of the consumer so they’ve aimed to combine that focus with function and fashion. Incorporating sports technology into the lens allows them to filter out damaging UVs and glare while providing heat and scratch resistance. In the end, the goal is to provide a luxury product that will endure decades of use without impacting the planet . Wouldn’t it be nice if more companies adopted this simple philosophy? + Just Human Images via Just Human

Comments Off on Virginia Utility Makes EV Charging Cheaper

Virginia utility Dominion Virginia Power has begun a pilot program that will allow EV owners to charge their batteries for half the cost as long as they do it overnight. The utility says that at off-peak rates, enough battery power for a 40-mile commute costs $0.86, but for the 750 EV owners who are part of the program, that cost will be lowered to $0.35.  The customers will use a specific charger installed for the program.

Comments Off on Help Create a Twitter Book for Copenhagen

Images from thisplace’09 We all can’t go to Copenhagen this week, but there are so many ways to make our voice heard nonetheless. ThisPlace09 is an art and Twitter project that conveys personal thoughts about climate change to the delegates and the rest of the participants so that they can see how the public feels about the importance of the issue. It’s a simple and effective idea: a selection of twitter comments about the environment are put together into a little book, together with lovely artwork, and given to delegates.
