Time to re-think the diesel
March 11, 2016 08:00 AM - Richard Howard / Policy Exchange, The Ecologist
Low Emissions Zones have their place in cleaning up the UK's worst air pollution hotspots, writes Richard Howard. But we also need to adopt fiscal measures to encourage a shift away from diesel vehicles, at once delivering cleaner air, increased tax revenues, and lower carbon emissions.
If we are to clean up air pollution in London and the rest of the UK, then Government needs to recognise that diesel is the primary cause of the problem, and to promote a shift away from diesel to alternatives.
There is an air pollution crisis taking place in London and many of the UK's other major cities.
'Ugly' fruits and vegetables will get a chance to be sold
March 11, 2016 07:09 AM - Leon Kaye, Triple Pundit
Depending on the source, anywhere from 20 to 40 percent of produce in America ends up wasted. One reason why so many fruit and vegetables are thrown out is because they do not conform to what retailers and consumers believe fresh food should look like. Tomatoes too wide for a hamburger bun, carrots that look like something out of an anatomy textbook, and cucumbers that dare to be curved almost never make the shelves at grocery chains from Walmart to Whole Foods. But Whole Foods, the supermarket that has arguably made organic and socially-conscious foods mainstream, announced that it will start selling “ugly” fruits and vegetables.
Record year for rhino poaching in Africa
March 10, 2016 07:19 AM - WWF Global
The number of African rhinos poached in 2015 is higher than previously thought with new figures from the International Union for Conservation of Nature (IUCN) showing that a record 1,338 were killed across the continent last year – 33 higher than earlier estimates.
This is the highest level since the current poaching crisis began in 2008 and takes the number of African rhinos killed since then to at least 5,940.
Study suggests impact of climate change on agriculture may be underestimated
March 8, 2016 07:10 AM - Brown University
Studies of how climate change might affect agriculture generally look only at crop yields — the amount of product harvested from a given unit of land. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.
Scientists fight deadly banana fungus
February 29, 2016 07:11 AM - Editors, SciDev.Net
Around the world, banana farmers are fighting a losing battle against Tropical Race 4, a soil fungus that kills Cavendish bananas, the only type grown for the international market. The disease was first spotted in the early 1990s in Malaysia, but has now started to wipe out crops in large parts of South-East Asia as well as in Africa and the Middle East.
Consumers have huge environmental impact
February 25, 2016 07:46 AM - Norwegian University of Science and Technology via EurekAlert!
The world's workshop -- China -- surpassed the United States as the largest emitter of greenhouse gases on Earth in 2007. But if you consider that nearly all of the products that China produces, from iPhones to tee-shirts, are exported to the rest of the world, the picture looks very different.
VW Emissions cheating scandal update
February 25, 2016 07:36 AM - Leon Kaye , Triple Pundit
Volkswagen is still struggling to move past the emissions-software scandal that has plagued its reputation for the better part of a year. Ever since the news officially broke that an array of its diesel passenger cars were outfitted with deceptive software, VW’s reputation has been pretty much at bottom ratings.
It’s not like the company hasn’t tried to regain public trust: To disgruntled consumers who bought one of the affected cars, it’s offered a combo of Visa cards and credit at dealerships. To dealers stuck with stock frozen by the publicity, the company offered to buy back used vehicles at full price. And in response to hundreds of class-action suits coming up on the horizon, the company recently suggested that it may be willing to buy back those vehicles that can’t be fixed. Fixing, VW lawyer Robert Giuffra explained in court in January, requires coming up with new software, and that may still be a long way off — too long for some earlier vehicles caught in the debacle.
Scientists unlock key to turning wastewater and sewage into power
February 23, 2016 07:16 AM - Virginia Tech
As renewable energy sources goes, solar rays have historically hogged the limelight.
But two Virginia Tech researchers have stolen the spotlight from the sun by discovering a way to maximize the amount of electricity that can be generated from the wastewater we flush down the toilet.
Can ecotourism save threatened species?
February 19, 2016 06:09 AM - Griffith University
Ecotourism can provide the critical difference between survival and extinction for endangered animals, according to new research from Griffith University.
Using population viability modelling, the Griffith team of Professor Ralf Buckley, Dr Guy Castley and Dr Clare Morrison has developed a method that for the first time quantifies the impact of ecotourism on threatened species.
The differences between organic and non-organic milk and meat
February 16, 2016 07:13 AM - Newcastle University
A new study has shown that both organic milk and meat contain around 50% more beneficial omega-3 fatty acids than conventionally produced products. Analysing data from around the world, the team led by Newcastle University, reviewed 196 papers on milk and 67 papers on meat and found clear differences between organic and conventional milk and meat, especially in terms of fatty acid composition, and the concentrations of certain essential minerals and antioxidants.
