In 1990, volunteers hatched an idea to kindle ecological understanding and stewardship among people in the neighborhood near Milwaukee’s Riverside Park. Their idea involved the environment, but their goal was to reduce the crime that gripped the neglected park.

That vision resulted in not just the flagship Urban Ecology Center, but two additional centers in Washington Park and the Menomonee Valley, which all play pivotal roles in their respective neighborhoods.

In the five years since earthquakes first began blitzing Oklahoma, state officials have been hesitant to agree with scientists who blamed the oil and gas industry.

The shaking doesn't appear to be slowing, but the regulatory response is ramping up as more state officials acknowledge the link between increased seismic activity and waste fluid pumped into the disposal wells of oil fields.

To show how an oil and gas boom fueled a massive surge of earthquakes, scientists used algorithms, statistics and computer models of fluid flow and seismic energy.

Word that Americans throw away about one-third of our available food has been getting around.

Now there's an official goal aimed at reducing that waste.

Today, the U.S. Department of Agriculture and the Environmental Protection Agency — along with many private-sector and food-bank partners — announced the first ever national target for food waste.

"[We're] basically challenging the country to reduce food waste by 50 percent by the year 2030," Agriculture Secretary Tom Vilsack tells The Salt.

It's difficult to keep up with the status of the dam, but probably not for the citizens of Glendale. It's where the dilapidated 70-plus-year-old structure stands in the Milwaukee River. Tuesday night, Glendale held a public information session to bat around the issue yet again.

Milwaukee County Board Chairman Theodore Lipscomb says many people don’t realize the dam has restored the Milwaukee River upstream to its more natural state.

Mount Aso — a volcano on Japan's southern main island of Kyushu — has erupted, spewing black smoke and ash more than a mile into the air, the Japanese Meteorological Agency says.

So far, there have been no reports of injuries or damage, but ash fell as far as 2.5 miles from the crater.

Mount Aso, which stands 5,222 feet high, is the country's largest active volcano.

Scientists today laid out a truly worst-case scenario for global warming — what would happen if we burned the Earth's entire supply of fossil fuels.

Virtually all of Antarctica's ice would melt, leading to a 160- to 200-foot sea level rise.

"If we burn it all, we're going to melt it all," says Ken Caldeira, a climate scientist at the Carnegie Institution for Science.
