Rhiannon Tomtishen and Madison Vorva, seventh-graders from Ann Arbor, Michigan, have been selling Girl Scout cookies for years. While researching a Bronze Award project on Indonesian orangutans, they were shocked to learn that the primate’s forest habitat is being replaced by palm oil plantations -- and Girl Scout cookies contain palm oil. This year the two girls will sell magazines instead. They’ve also launched a Web site, www.saveorangutan.bravehost.com.
