To spray or Not to spray
According to the U.S.Fish & Wildlife service,silversword (Argyroxiphium sandwicense)plants,located in Haleakala National Park on Maui,Hawaii,have been a threatened species since 1922.Over the years,human vandalism along with browsing by domestic cattle and feral goats have reduced the number of silverswords to a fraction of their former abundance.Recently,park staff members have become concerned about the damage that insects appear to be doing to the park's silversword.An entomologist suggests that insects may be damaging the plants to the point that almost no seeds are being produced.
The park's superintendent is being pressured to start a program for spraying the silverswords with a pesticide to take the stress of insect predation off the plants and increase their chances of reproducing.Do you think the superintendent should begin a spraying program
