How Farm Pests Can Threaten Food Security
September 2, 2014 12:49 PM - Tim Radford, The Ecologist
Agricultural pests - viruses, bacteria, fungi, blights, mildews, rusts, beetles, nematodes, flies, mites, spiders and caterpillars - are spreading thanks to trade, travel and global warming, writes Tim Radford. The world faces a dire future of increased crop losses and growing insecurity. Coming soon to a farm near you: just about every possible type of pest that could take advantage of the ripening harvest in the nearby fields.
Reducing Water Scarcity
August 29, 2014 02:53 PM - McGill University
Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials last year warned residents of Arizona and Nevada that they could face cuts in Colorado River water deliveries in 2016. Irrigation techniques, industrial and residential habits combined with climate change lie at the root of the problem. But despite what appears to be an insurmountable problem, according to researchers from McGill and Utrecht University it is possible to turn the situation around and significantly reduce water scarcity in just over 35 years.
"Global Roadmap" Created to Balance Development with Environmental Protection
August 28, 2014 11:49 AM - Morgan Erickson-Davis, MONGABAY.COM
Roads make it possible to bring goods to market, to get to the office, to log a forest, to hunt its wildlife. Without roads, human society as we know it could not exist. However, to build roads, trees must be cleared and swamps drained, shrinking valuable wildlife habitat and fragmenting populations in the process. A new study, published today in Nature, unveils an innovative map that defines which areas of the world would best be used to build roads — and which should be left alone. Scientists estimate more than 25 million kilometers of new roads will be built worldwide by 2050, representing a 60 percent increase over 2010 numbers. Many of these are slated for environmentally valuable places with high numbers of unique species and pristine forest, such as the Amazon Basin.
Uncontrolled Trash Burning Significantly Worsens Air Pollution
August 26, 2014 04:20 PM - UCAR AtmosNews
Unregulated trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research estimates that more than 40 percent of the world's garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.
Levels of Air Toxics decreasing across US Cities
August 23, 2014 07:07 AM - Roger Greenway, ENN
More and more people are living in our cities. They are great places to live, exciting, good jobs, great night life, but also sometimes congestion and unhealthy air quality. The latter problems are improving, however. Efforts to make cities livable without driving are paying off. Bike lanes, bike sharing, and efforts to reduce auto traffic and congestion are helping to improve the air quality in our cities. The U.S. Environmental Protection Agency (EPA) this week released its Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics. "This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we have been protecting Americans — preventing illness and improving our quality of life by cutting air pollution - all while the economy has more than tripled," said EPA Administrator Gina McCarthy. "But we know our work is not done yet. At the core of EPA's mission is the pursuit of environmental justice - striving for clean air, water and healthy land for every American; and we are committed to reducing remaining pollution, especially in low-income neighborhoods."
The cost of marine debris
August 12, 2014 03:53 PM - NOAA
Marine debris has many impacts on the ocean, wildlife, and coastal communities. A NOAA Marine Debris Program economic study released today shows that it can also have considerable economic costs to residents who use their local beaches. The study found that Orange County, California residents lose millions of dollars each year avoiding littered, local beaches in favor of choosing cleaner beaches that are farther away and may cost more to reach. Reducing marine debris even by 25 percent at beaches in and near Orange County could save residents roughly $32 million during three months in the summer.
Bottling Water from Drought Stricken Areas
August 12, 2014 07:55 AM - Leon Kaye, Triple Pundit
The bottled water industry has grown exponentially the past few decades despite the fact tap water in the United States is generally safe. Never mind the fact bottled water producers have had more than their fair share of safety issues: bottled water has become accepted by consumers. While companies such as Nestlé insist they are taking responsibility for water stewardship and recycling, they also bottle their water at dubious sources, including those in drought stricken regions.
The Danger of Solar "Super-Storms"
August 5, 2014 01:45 PM - Winfield Winter, ENN
Watch out George Lucas fans, a Death Star may be in our horizons — and one would only have to look as far as our nearest stellar neighbor: the Sun. According to Mr. Ashley Dale of the University of Bristol, solar "super-storms" pose an imminent threat to the earth by disabling electricity and communication system — or worse. Thus, the celestial body that illuminates the world may very well be responsible for sending it into darkness. In this month's issue of PhysicsWorld, Mr. Dale writes: "Without power, people would struggle to fuel their cars at petrol stations, get money from cash dispensers or pay online. Water and sewage systems would be affected too, meaning that health epidemics in urbanized areas would quickly take a grip, with diseases behind centuries ago soon returning."
Survey Ranks U.S. as Biggest Climate Change Denier
August 5, 2014 08:27 AM - RP Siegel, Triple Pundit
This may confirm suspicions that many of us have already had. Besides leading the world in consumer debt and military spending, the U.S. can now add climate denial to that list. That is, according to a Global Trends survey by the U.K.-based market research firm Ipsos MORI. The study polled 16,000 people in 20 leading countries on eight different topics, including the environment. Not only was the U.S. last, but it was last by a considerable margin.
Co-evolution Benefits Aborigines and Kangaroos
August 4, 2014 09:01 AM - University of Utah
Australia's Aboriginal Martu people hunt kangaroos and set small grass fires to catch lizards, as they have for at least 2,000 years. A University of Utah researcher found such man-made disruption boosts kangaroo populations — showing how co-evolution helped marsupials and made Aborigines into unintentional conservationists. "We have uncovered a framework that allows us to predict when human subsistence practices might be detrimental to the environment and when they might be beneficial," says Brian Codding, an assistant professor of anthropology.
