Why Are Traffic Deaths Rising?

The battle to reduce traffic fatalities may have hit a roadblock after showing impressive results over the past several years. The latest federal estimates show an 8 percent uptick in traffic deaths over the first half of 2015 compared to the prior year. While the projection covers a short time period, it’s the highest first-half tally since 2009.Traffic safety advocates point to two main factors behind the increase. One is the improving economy, as Americans are traveling more. The other likely culprit is the wide variance in state laws that, according to advocates, aren’t doing nearly enough to curb fatalities.When the economy took a downturn, so too did traffic deaths. But economic recoveries generally coincide with higher fatality rates because families have more discretionary income, take extra vacations and travel more on weekends. Parents also tend to purchase more cars for teenagers, who face the highest risk of accidents.

World Water Day 2016: About

World Water Day is an international observance and an opportunity to learn more about water related issues, be inspired to tell others and take action to make a difference. World Water Day dates back to the 1992 United Nations Conference on Environment and Development where an international observance for water was recommended. The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day. It has been held annually since then. Each year, UN-Water — the entity that coordinates the UN’s work on water and sanitation — sets a theme for World Water Day corresponding to a current or future challenge. The engagement campaign is coordinated by one or several of the UN-Water Members with a related mandate.

To save the climate, use more energy? : TreeHugger

We’ve written a lot about demand response schemes where businesses power down when energy is scarce. It’s an approach that makes sense. And it can help allay fears about the intermittency of many renewable sources.Now Business Green reports on a related, but perhaps somewhat counterintuitive, idea. A company called Flexitricity is working with companies to turn up their demand at times when wind energy is plentiful. The service gives businesses a heads-up when wind production is likely to outstrip demand, and if those companies can make use of the energy by ramping up production, they receive a payment in addition to the electricity they receive.Here’s how Dr Alastair Martin, chief strategy officer at Flexitricity, explained the value in a press release:”Footroom, or demand turn-up, offers tremendous potential to the UK—not only does it put the country at the very forefront of developing and implementing the grid of tomorrow, but it opens up a world of possibilities for business and for renewables developers, With Footroom, businesses can boost productivity for minimal extra cost and are incentivised to do so. In turn, the grid can increase the amount of electricity distributed to homes from clean, renewable energy sources.”

Midwestern geothermal greenhouse provides local citrus year round for $1 a day : TreeHugger

Greenhouse in the Snow, built by a former mailman, grows an abundance of local produce high on the Nebraska plains.”We can grow the best citrus in the world, right here on the high plains,” says Russ Finch, the former mailman (pictured above) who is the creative superstar genius responsible for building the Greenhouse in the Snow. And he can do it spending only $1 a day in energy costs.For Midwesterners (and many of the rest of us) produce in the winter means things imported form warmer climes or grown in greenhouses, which typically have a prodigious hunger for energy and are fed by burning fossil fuels.But by harnessing the Earth’s natural internal heat to warm a greenhouse, oranges and other tropical treats thrive without the waste and pollution typically found in so much agriculture. Finch’s structure is a take on a walipini – a brilliant design that TreeHugger has written about (and which remains one of our most popular posts: Build a $300 underground greenhouse for year-round gardening).As Grant Gerlock writes at NPR, the floor is dug 4 feet below the surface, the roof is slanted toward the south to harness as much sun as it can. In the daytime it can warm well into the 80s inside, but at night the temperature drops, which is when the geothermal heat is called in.
