Name as many general strategies from this chapter as you can for using the semiattachedfigure. (I count roughly half a dozen.)3. Here is an excerpt from a guest commentary column in the Santa Maria Times byRon Fink (May 17, 2005). See how many semi-attached figures you can spot.The North [Santa Barbara] County routinely meets state air quality standardsand the South Coast does not. Why is that? ... The South Coast doesn’t have anymore industrial pollution emitters than does the north. Failure to meet the standardmay be connected to the 71 tons of methane that is released daily from natural seepsoff of our coastline, not any human activities. You see, the instruments used tomeasure air contaminates [sic] cannot discriminate between natural and man-madepollutants.Nature is not perfect when judged by man’s rules for polluting theenvironment. Anyone with a pollen-associated sinus problem can readily attest to theimpact that nature has on our daily lives.And what about those greenhouse gases, the purported cause of globalwarming, where do they come from? A major source is volcanoes…. Satellite dataafter the 1991 eruptions of Mt Pinatubo (the Philippines) and Mt Hudson (Chile)showed a 15-20 percent ozone loss at high latitudes and a greater than 50 percent lossover the Antarctic! … The U.S. Geological Survey determined that: globally, largevolcanic explosive eruptions that inject a tremendous volume of sulfur aerosols intothe stratosphere can lead to lower surface temperatures and promote depletion of theEarth’s ozone layer. Ash from such events [as the Mt St Helens eruptions] can travel100 miles or more downwind!
