Nearly half of US seafood supply is wasted
September 24, 2015 03:13 PM - Johns Hopkins University Bloomberg School of Public Health
As much as 47 percent of the edible U.S. seafood supply is lost each year, mainly from consumer waste, new research from the Johns Hopkins Center for a Livable Future (CLF) suggests. The findings, published in the November issue of Global Environmental Change, come as food waste in general has been in the spotlight and concerns have been raised about the sustainability of the world’s seafood resources.
Just how much waste are Americans creating?
September 23, 2015 09:09 AM - Tex Dworkin, Care2
A new Yale-led study reveals that we’re disposing of more than twice as much solid waste as we thought we were here in the good ol’ U.S. of A.
Published on Sept. 21 in the Nature Climate Change journal and co-authored by Yale professor Julie Zimmerman and University of Florida professor Timothy G. Townsend, this study found that based on landfill measurements instead of government estimates, analysis of figures revealed that America tosses five pounds of trash per person per day.
Let that soak in for a moment. Five pounds of garbage. Per day. Per person. But it gets better, and by better, I mean worse.
Feds Set Food Waste Reduction Goals
September 22, 2015 08:49 AM - Gina-Marie Cheeseman, Triple Pundit
Food waste in the U.S. is a big problem, accounting for about 31 percent of the nation’s food supply, or 133 billion pounds. It makes up 21 percent of U.S. municipal solid waste in landfills, and as a result it accounts for the lion’s share of landfill methane emissions. Methane is a greenhouse gas with a warming potential 21 times that of carbon dioxide — and landfills are the third largest source of methane emissions in the U.S.
Alarming report on the health of our oceans
September 20, 2015 06:29 AM - Alicia Graef, Care2
The sheer vastness of the oceans on this planet make it seem almost impossible that our actions could bring them to the point of no return, but a new report has found that we are causing an alarming decline of marine ecosystems and the species who rely on them.
According to the World Wildlife Fund‘s (WWF) recently released Living Blue Planet Report, marine populations have declined by an astonishing 49 percent between 1970 and 2012, with with some fish species, including tuna, declining by almost 75 percent.
Are "sustainable" pet foods better?
September 17, 2015 06:43 AM - Leon Kaye , Triple Pundit
Many of its brands — and commercials — may be iconic, from Meow Mix to Alpo, but the fact is that the pet food industry is a relatively new business. For millennia, cats and dogs were simply fed unwanted table scraps. Go to a timeless fish market like the Besiktas in Istanbul, and the chances are high that visitors will see a fishmonger feeding a feline the day’s scraps. Wander through the timeless Central Market in Athens and observers will watch the same thing, only with tidbits of beef and lamb.
Fast forward to the post-World War II era, however, and it was then that many food companies saw the benefits of marketing formulated pet foods to dog and cat owners. Growing affluence and the demand for convenience together inspired companies including General Foods, Nabisco and Purina (now owned by Nestlé) to enter the pet food sector. The profit margins were huge, as food waste that previously would have been discarded was recycled into what quickly became a lucrative new business.
World's First Solar-Powered Airport
September 14, 2015 03:51 PM - Tex Dworkin, Care2
Aviation history has just been made. Earlier this summer I told you about the record breaking solar plane flight, and now the solar eagle has landed again—this time at an airport in India that just became the first airport in the world to completely operate on solar power.
Diesel cars in the EU having trouble meeting emissions standards on the road
September 14, 2015 02:19 PM - ClickGreen Staff, ClickGreen
Every major car manufacturer is selling diesel cars that fail to meet EU air pollution limits on the road in Europe, according to data obtained by sustainable transport group Transport & Environment (T&E).
All new diesel cars should have met the Euro 6 autoemissions standard from 1 September – but just one in 10 tested complied with the legal limit.
On average new EU diesel cars produce emissions about five times higher than the allowed limit. The results are compiled in a new report, Don’t Breathe Here, in which T&E analyses the reasons for and solutions to air pollution caused by diesel machines and cars – the worst of which, an Audi, emitted 22 times the allowed EU limit.
Why are some people so negative about electric cars?
September 13, 2015 07:46 AM - MARK BENSON, Electric Forum
Sometimes it is good to take stock, sit back and take a look at the wider picture in relation to the electric car market. Each day seems to bring yet another raft of criticism, concerns and cheap shots at an industry which has come on in leaps and bounds over the last decade. While where we are today is certainly some way from the finish line there is no doubt that amazing progress has been made with the likes of Tesla pushing the industry to new highs.
So, why are people so negative about electric cars and unable or unwilling to appreciate the technology which it has created?
MIT study shows climate change mitigation potential of geoengineering the oceans
September 9, 2015 07:23 AM - Mark Dwortzan | Joint Program on the Science and Policy of Global Change, MIT
Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl sulfide (DMS) into the atmosphere, where it forms sulfate aerosols, which can directly reflect sunlight or increase cloud cover and reflectivity, resulting in a cooling effect. The ability of phytoplankton to draw planet-warming carbon dioxide (CO2) from the atmosphere and produce aerosols that promote further cooling has made ocean fertilization — through massive dispersal of iron sulfite and other nutrients that stimulate phytoplankton growth — an attractive geoengineering method to reduce global warming.
Coastal management strategies in the age of climate change
September 4, 2015 05:52 AM - ClickGreen staff, ClickGreen
Coastal decision-makers must move away from considering physical and economic forces in isolation to fully recognise and explain changes to coastlines, according to new research from Cardiff University.
The coastlines where we live, work and play have long been altered by people, but now researchers have investigated why developed coastlines change over time in ways that are fundamentally different from their undeveloped, natural counterparts.
