Penguins Affected by Tourism in Antarctica
December 29, 2014 09:16 AM - Alicia Graef, Care2

A trip to Antarctica might not be a dream vacation for everyone, but it’s on the list for many who are clearly willing to trek to there. While tourists are busy exploring the scenery and greeting the penguins who live there, scientists are raising concerns about how exposure to us could increase their risk of contracting infectious diseases. Scientists and disease experts believe the immune systems of penguins, and other species in the region, are less able to deal with pathogens that are commonplace in the rest of the world because they’ve been isolated for so long with few visitors.

New study analyzes sound sensitivity of marine invertebrates
December 22, 2014 02:57 PM - Woods Hole Oceanographic Institution

Noise pollution in the ocean is increasingly recognized as harmful to marine mammals, affecting their ability to communicate, find mates, and hunt for food. But what impact does noise have on invertebrates -- a critical segment of the food web? Very few studies have attempted to answer that question. The harder question to answer might be 'How do you measure hearing in ocean invertebrates'? A new study by researchers at Woods Hole Oceanographic Institution and their colleagues examined behavioral responses to sound by cuttlefish, a type of shell-less mollusk related to squid and octopi. The study is the first to identify the acoustic range and minimum sound sensitivity in these animals. Their findings, published in the Journal of Experimental Biology, can help decision makers and environmental managers better understand the impacts of noise in the ocean.

How the Credit Car Industry is Contributing to Pollution

Guest Contributor, Odysseas Papadimitriou

We all get far too much mail, especially from financial services companies.  Credit card companies alone send billions of pieces of paper mail each year, and most of that gets thrown right into the trash can.  Not only does this dynamic pose a threat from a fraud perspective – trash cans and mailboxes can be treasure troves for opportunistic fraudsters – but you have to figure the effect on the environment isn’t great either. Paper products aren’t as bad as most materials, according to North Carolina State University Professor Richard Venditti, because they’re renewable, recyclable and biodegradable and they motivate land owners to plant trees.  However, Venditti says, “inefficient use of paper does consume resources and have an impact on the environment.” While credit card direct mail is on the rise after hitting a two-year low in April 2012, long-term trends suggest a declining role for traditional paper mail in the years to come.  Not only are financial services companies increasingly offering paperless options to their account holders – even charging extra for paper statements, but they’re also learning how to better leverage digital means for marketing purposes.  These changes are largely based on the shifting preferences of the modern consumer as well as the overall technicalization of modern commerce – not some newfound corporate altruism – but does it really matter?
