Waste Not, Want Not — Reducing Food Waste in America

In the United States, 40 percent of all food produced remains uneaten. Some of this food has spoiled, some of it was left in the fields to rot, and some of it never made it to market after being harvested. According to the United Nations Food and Agriculture Organization (FAO), Americans routinely throw away about 20 pounds of food per month, which equates to about $28-43 worth of food. In all, it is estimated that $165 billion are squandered each year when perfectly edible food goes uneaten. Why is there so much food waste? And what can you do about it?

Every month, an average of 40 volcanoes erupt on land into the atmosphere, and hundreds of others on the seafloor erupt into the ocean. Predicting when these eruptions will occur is nearly impossible. Scientists associated with the Deep Carbon Observatory (DCO) and Deep Earth Carbon Degassing (DECADE) initiative are setting the stage to make accurate volcanic eruption forecasts a reality.

Scientists Solve Mystery of Deadly 1952 London Fog

Though London is well known for its overcast and foggy weather, the fog that enveloped the city for four days in 1952 was a fog like no other. By the time the fog lifted, at least 4000 people were dead and more than 100,000 people had been hospitalized. In addition, thousands of animals, including many livestock, also died. What caused this particularly deadly fog has long been unknown. Now scientists think they have finally solved the mystery behind the killer fog. Their findings may help prevent a similar event from occurring in modern-day China, which is home to 16 of the 20 most polluted cities in the world. [Read more…]

New research indicates that six of seven native forest birds found on the island of Kauai in Hawaii are quickly disappearing from the landscape and their range is rapidly contracting. All six of these species are honeycreepers, and four are only found in small, remote locations. The reason for this collapse, as reported in an article in the journal Science Advances, is the spread of avian malaria by mosquitoes. The mosquitoes have been able to expand their territory upward due to climate change and global warming. [Read more…]
