Given Antarctica’s geographic isolation and extreme climate conditions, is has long been an area of interest to scientists. But what happens to all the waste generated by the annual influx of scientists and their support staff? [Read more…]

Waste Not, Want Not — Reducing Food Waste in America

Food waste is a major component of solid waste in landfills. Decomposing food creates methane, a potent greenhouse gas. (Photo credit: g215/Shutterstock)

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.

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…]

Home gardening has grown greatly in popularity over the past five years. According to research gathered by the National Gardening Association, 42 million households grow food at home or in a community garden. The greatest surge in home gardeners is among millennials (those between 18 and 34 years of age); over the past five years, food gardening among this age group has increased 63 percent. [Read more…]

Coral reef bleaching is occurring at an unprecedented rate on Australia’s Great Barrier Reef. A recent aerial survey of 911 reefs by Australia’s National Coral Bleaching Task Force found evidence of bleaching on 93 percent of the reefs. The damage is most severe in the Great Barrier Reef’s northern section, where no reef has escaped bleaching. To put this in perspective, the bleaching is currently affecting an area about the size of the state of Maine. [Read more…]
