Environmental Dangers/ Benefits

Mt. Hood's Hood River Valley is known for its fertile soil because of the lush forests around its area and some fruit industries that have set up there. But, there its danger to these industries and the environment around them. If the volcano was to go off lahars, mudflows and pyroclastic flows could damage Mt.Hood Highway and Warmsprings Highway, local ski lodges, Rooster Rock national park, and these forests and fruit industries, and anything along the Columbia River and Mt. Hood River. Also, on a regular basis Mt. Hood will occasionally emit carbon dioxide and sulfur dioxide which are poisenous when exposed to for long periods of time and add carbon dioxide to the atmosphere which in some mindsets adds to "global warming".
