单选题Greenstreak is an international non-profit agency dedicated to the preservation of natural habitats and the animals that rely on them. With offices in over 20 countries, Greenstreak is one of the leading organizations in the fight to preserve our world's precious resources. Since 1946, Greenstreak has worked with nonprofit groups, world leaders in politics, business and industry, and government organizations like the United Nations to change the way people think about conservation. As part of our mission, Greenstreak offers a number of courses for interested individuals and groups of all levels on a range of topics related to ecology, biology, green riving, and conservation. We have a great deal of experience speaking to youth groups, schools, university symposia, and government conferences. In the interest of spreading the important message about honoring our planet, Greenstreak can customize a presentation to the specific needs of any group. If your organization is interested in having Greenstreak show up at your next event, please call your local Greenstreak office or visit us on the Web at www.greenstreak.org. From: bartmanstead@schools.greenbrier.alberta.ca To: events@greenstreak.org.ca Date: April 13, 01:40.23 p.m. Good morning! My name is Bart Manstead, and I'm a science teacher at Greenbrier Middle School in Greenbrier, Alberta, Canada. We are arranging a special science fair for Earth Day this year at the school. I'm currently in the process of organizing guest speakers for the event, and I would like to extend an invitation to Greenstreak to be our Guest of Honor. We are a regional middle school for students in 5th through 8th grades (about 11-14 years old) for the city of Greenbrier and a number of surrounding districts. We have approximately 3,500 students at the school. In order to determine if Greenstreak can provide what we're looking for, I would appreciate it if you could send me more information about your presentations. Obviously, any kind of seminar would have to fit the needs of our students, the limits of our facilities, and the school budget. However, we would be delighted to arrange for you to be present at our science fair. Please reply at your convenience with the requested information. Thanks! Bart Manstead
