Oregon Shellfish Loaded With Chemicals
Researchers from Portland State University have found a worrying cocktail of drugs and other suspect chemicals in Oregon oysters. Although individually the substances fell within safety guidelines, little is known about the combined effects of these chemical agents. The Statesman has the story: http://www.statesmanjournal.com/story/tech/science/environment/2016/05/02/oregon-oysters-contain-drugs-toxins-researchers-say/83838580/

Ocean Oxygen Loss Quantified and Predicted 
The National Center for Atmospheric Research has crunched the data to measure and predict the loss of oxygen from the world’s oceans, due to global warming. A tipping point is now expected in the 2030s. This has powerful implications for all life in the oceans, as well as those, such as humans, which depend on the seas’ bounty.

Climate Change Threatens Crater Lake’s Waters 
Scientists are concerned that the dynamics climate change could bring to Crater Lake may turn its legendary crystalline waters murky. The Oregonian explains the reasons for concern: http://www.oregonlive.com/travel/index.ssf/2016/05/climate_change_could_threaten.html#incart_river_index

The Elephant in the Corner of the Global Warming Room 
In tackling the roots of climate change, and often other forms of pollution, agriculture is often passed by as too crucial, or too ensconced to address. An international team of scientists has concluded that’s just not good enough. The BBC has more on the dilemma posed by the growing of crops that is killing the planet: http://www.bbc.com/news/science-environment-36315952

Cruise Ships’ Dirty Secret 
As cruise ships get bigger, the environmental impact they have scales out of control. Consider this: The Royal Caribbean ship Harmony burns through some of the dirtiest diesel fuel out there at the rate of 66,000 gallons a day. And that’s just one tip of a multifaceted iceberg. Let the Guardian inform you: http://www.theguardian.com/environment/2016/may/21/the-worlds-largest-cruise-ship-and-its-supersized-pollution-problem

Testing Assumptions About Legal Hunts and Poaching 
Researchers recently put to the test the received wisdom that allowing legal hunts can reduce poaching. The results of their investigation draw the old assumptions very much into question. The BBC reports: http://www.bbc.com/earth/story/20160510-why-it-is-a-bad-idea-to-let-people-hunt-wolves
