Bubbling brooks and streams are a scenic and much loved feature of forest ecosystems, but long-term data at Hubbard Brook Experimental Forest suggests that more productive forests might carry considerably less water.
Though not in the news as much as it once was, acid rain remains a problem. Power plants, factories, and vehicles give off sulfur and nitrogen oxide emissions, which react in the atmosphere to form sulfuric and nitric acids. These acids are then deposited back onto the landscape in rain, snow, fog, or particles.
