Mount Hood last erupted more than 200 years ago, but at Crater Rock, not far from the summit, the signs of volcanic activity are unmistakable. Gas vents and hot springs emit sulfur fumes. Vapors rising from deep under the mountain carve snow caves, which can seem like sanctuaries for climbers but often hold deadly concentrations of CO2 and other gases. Rocks fall frequently from the steep unstable cliffs of the partially collapsed crater.

When the Earth burps, WeiLi Hong listens. Whether Earth’s gaseous emissions bubble up from “mud volcanoes” on the planet’s surface or seep out of fissures on the ocean floor, the Oregon State University Ph.D. student has his monitoring gear to the ground.
Green mulch
Plastic mulch — those shiny sheets spread across row upon row of veggies, strawberries and other crops — enables farmers to produce more types and greater quantities of food. It makes farming more profitable, preserves soil moisture, reduces weeds and saves on labor costs. But this type of mulch lasts for only a single growing season. After that, it gets dumped in landfills or is torched in the field — right here in the Willamette Valley and as far away as China.
