How to Make Your Home Smart and Energy Efficient
July 2, 2014 07:43 AM - Jessica Oaks, Triple Pundit
You may not realize it, but at this very moment, you’re probably wasting electricity. Don’t feel too bad though; the fact of the matter is, most people are using more electricity than they need. The home is filled with electronic devices, and keeping track of them all can be a real hassle. Most of us tend not to think about it. After all, what damage can possibly be done by leaving the lights on in a room or setting the thermostat a couple of degrees cooler? Well, more than you probably think. When it comes to electrical usage, one should think of the age-old economic theory, the Tragedy of the Commons. The principle is simple: Individuals acting rationally and in their own self-interest can actually act against the best interests of the group, by wasting a common resource needed by the collective whole. You may not believe that you’re using an exorbitant amount of electricity, but over time, this usage adds up. And this usage burdens the electrical grid and increases your spending. Thankfully, by being conscious of this fact, you can make changes that benefit your wallet, and the community as well.
Is Oceanic Plastic being eaten by fish?
July 1, 2014 07:38 AM - ANGUS CHEN, ScienceNOW
Millions of tons. That's how much plastic should be floating in the world's oceans, given our ubiquitous use of the stuff. But a new study finds that 99% of this plastic is missing. One disturbing possibility: Fish are eating it. If that’s the case, "there is potential for this plastic to enter the global ocean food web," says Carlos Duarte, an oceanographer at the University of Western Australia, Crawley. "And we are part of this food web."
World’s Protected Areas Not Protecting Biodiversity
June 30, 2014 02:53 PM - Wildlife Conservation Society
Scientists from James Cook University, the Wildlife Conservation Society, the University of Queensland, Stanford University, BirdLife International, the International Union for Nature Conservation, and other organizations have warned that the world's protected areas are not safeguarding most of the world's imperilled biodiversity, and clear changes need to be made on how nations undertake future land protection if wildlife is going to be saved. These findings come at a time when countries are working toward what could become the biggest expansion of protected areas in history. The authors of the new study found that 85 percent of world's 4,118 threatened mammals, birds, and amphibian species are not adequately protected in existing national parks, and are therefore vulnerable to extinction in the near term. The new study appears in the esteemed international journal PLOS Biology.
Why can't we recover precious metals from landfills?
June 30, 2014 08:17 AM - CleanTechies, Clean Techies
Mining for precious metals like gold, silver, and copper is extremely costly. Not only does it require a huge amount of energy and have a devastating impact on the environment, it also puts human life at risk. Still, these metals are what enable our precious smartphones and tablets to work so efficiently, so we have to get them from somewhere. But what if that somewhere was old gadgets we no longer want instead of deep within the Earth?
Endangered Species Act may be significantly weakened by new policy
June 28, 2014 07:52 AM - Center for Biological Diversity
The Center for Biological Diversity will file a legal challenge to an Obama administration policy, finalized today, that severely limits when a species qualifies for protection under the Endangered Species Act - a change that ignores both broad legal precedent and congressional intent. Under the Act a species qualifies for protection when it is "in danger of extinction in all or a significant of portion of its range." Both Congress and the courts have explained that the "significant portion of range" provision is vital for important conservation because it allows federal wildlife agencies to protect species before they are at risk of going extinct globally. But the newly finalized policy sharply restricts the use of this part of the Act, defining "significant" to mean that only when the loss of a part of a species' range threatens the survival of the whole species would wildlife agencies protect that species under the Act.
EPA Proposes Approval of New Climate-Friendly Refrigerants
June 27, 2014 03:56 PM - USEPA Newsroom
In support of President Obama's Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is proposing to increase the options for refrigerants in the United States that offer better climate protection without harming the ozone layer. This is the agency's first action that addresses refrigerants under the Climate Action Plan, which calls on EPA's Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals.
Connecting population growth and biodiversity decline
June 27, 2014 08:11 AM - Jeremy Hance, MONGABAY.COM
It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billion—for a total of 11 billion—by century's end. Despite this few scientists, policymakers, or even environmentalists are willing to publicly connect incredible population growth to worsening climate change, biodiversity loss, resource scarcity, or the global environmental crisis in general.
Farmed fish, the dark side
June 27, 2014 06:24 AM - Roger Greenway, ENN
It seems as more and more of the fish available to us in the supermarket and in restaurants is farmed. Is this good or bad? Probably a bit of both. Raising fish in fish farms doesn't impact the wild fish to any great extent, but fish farms must be well situated, and well run to prevent problems. They are not natural ecosystems! Aquaculture has become a booming industry in Chile, with salmon and other fish farmed in floating enclosures along the South Pacific coast. But as farmers densely pack these pens to meet demand, diseases can easily pass between fish — for example, an outbreak of infectious salmon anemia that emerged in 2007 caused the deaths of more than a million fish and threatened to cripple the industry. And unsustainable aquaculture methods can have a wider impact, spreading disease to the world’s already vulnerable ocean fisheries and contaminating the environment.
Choosing the Right Path: How Air Travel Affects Climate Change
June 26, 2014 10:40 AM - Winfield Winter, ENN
It has been well documented that one negative of air travel — besides the food — is the emission of CO2 from jet engines. But what about contrails? Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishing’s journal Environmental Research Letters. According to their report, contrails may have a greater radiative forcing (the capacity for an agent to enact climate change via warming) than CO2.
Solar Power Meets Half of Germany's Energy Demand
June 26, 2014 10:00 AM - Andrew Burger, Triple Pundit
A core facet of Chancellor Merkel's historic "Energiewende" clean energy transition, Germany has led the world in driving adoption of solar energy technology and systems. Although it is now pulling back hard on incentives, the market momentum created by its precedent-setting solar energy feed-in tariff (FiT) persists.
