Introduction to Persistent, Bioaccumulative, Toxic (PBT) Compounds in the Environment
October 24, 2013 05:03 PM - Robin Blackstone, ENN
Global chemical contamination is a worldwide concern affecting every being on earth. Chemical exposure, whether it is through air, water, plants, soil or our modern living environment is unavoidable. But certain chemicals and compounds having Persistent, Bioaccumulative, Toxic (PBT) characteristics are more dangerous to our environment than others because of their inability to break down easily, are easily transferred throughout all forms of environmental media, and posing risks to human health and the ecosystem due to their toxicity at low concentrations.
Ecology: Life's Connections
October 24, 2013 04:41 PM - Glen Barry, Ecologist
Ultimately, all humanity and all life have is the biosphere, the thin layer of life just above and below Earth’s surface, composed of ancient, miraculously evolved natural ecosystems. The natural Earth is a marvel - a complex coupling of species within ecosystems, whereby life begets life. Ecology is far more than the study of life and its environment. The word is used here as a synonym for ecosystems - the vibrant connections that emerge between species across scales, which cumulatively make life on Earth possible.

No More Trick to the Wrapped Treat

Halloween wouldn't be the same without a candy treat. Indeed we buy more candy at Halloween than we do for any other holiday. The National Confectioners Association estimates that consumers will spend $2.4 billion in candy this year for Halloween. The trick is that most of these candy wrappers will end up in a landfill.
Suggestions for restaurants to reduce food waste
October 18, 2013 06:48 AM - Jacquelyn Ottman, Triple Pundit
People care about food waste for all kinds of reasons, starting with moral issues such as global hunger, environmental reasons including carbon footprint (food waste decomposes in landfills into methane, a potent greenhouse gas), and even health concerns like obesity. Despite all the attention traditionally given to leftovers, food scraps, uneaten crusts of bread, our consumers seem to be especially concerned about food waste away from home, and they are willing to take steps to deal with it that have implications for restaurant branding and practices, particularly regarding portion control and choice of doggie bags.
