&2008中国知网(cnki) 中国学术期刊(光盘版)电子杂志社游人涌入垃圾问题太头疼 Great Barrier Island发呼吁

图片来源：网络&&& 天维网12月20日综合报道 假期即将到来，居民出游的热潮也即将到来，而Great Barrier Island则向来是备受游客和游艇爱好者们青睐的出游地。不过，大批游客涌入，却留下大量垃圾，这样的状况，令当地居民不堪其扰。近日，Great Barrier Island居民就发出呼吁，希望游客能在离岛时将垃圾处理好或是带走。&&& 届时，Great Barrier Island将在主要的交通枢纽置放垃圾桶，负责收纳含塑料、铝、玻璃、纸张和纸板在内的可回收垃圾。&&& Great Barrier Island固体垃圾经理Ian Stupple表示，这些可回收垃圾将需要从岛上被运往奥克兰进行处理，而这笔费用，将由奥克兰的纳税人们支付。“而游客遗留下来的不可回收垃圾将被运往当地的垃圾填埋场。如果游客能够将垃圾进行正确分类，并在可能的情况下自己将垃圾带离，将会大有帮助。”&&& 而对于那些游艇爱好者们来说，将于12月20日至2月5日之间在Fitzroy Harbour港口停泊的一条驳船将成为他们的“最佳选择”，游艇爱好者们可以将少量混杂的垃圾运送至驳船之上。&&& 需要注意的是，在高峰时段，游客丢弃垃圾的数量很有可能会被限制，因此，游客需要配合不同垃圾收集地的相关规定。&&& 据预计，在即将到来2周圣诞假期内，将有约700艘船此驶往Great Barrier Island，此外，在整个夏季，都会有大量游客开船、搭乘渡轮或是飞机前往岛上度假，而这无疑将为当地公共服务和社会资源带来巨大压力。&&&

The Barrier Island Sanctuary Management and Education Center (Barrier Island Center) is an educational center is located in the heart of the Archie Carr Refuge, a major nesting site for sea turtles. Through a partnership with the Brevard County Environmentally Endangered Lands Program (EELS), the Sea Turtle Conservancy manages and conducts the educational programs offered at the Barrier Island Center.

In North America, sea turtles primarily nest from North Carolina through Florida, with over 90% occurring in Florida. Within that range is the Archie Carr National Wildlife Refuge, a 20.5-mile section of shoreline between Melbourne Beach and Wabasso, along Florida's east central coast. Since its establishment by Congress in 1989, the Carr Refuge, named after STC's founding scientific director, has been a major success. The stretch of beach within the Refuge boundary is home to the most important sea turtle nesting habitat in the United States. More loggerheads nest within the Carr Refuge than anywhere else in the Western Hemisphere. In addition, over the past several years there has been a significant increase in both green turtle and leatherback nesting. Protection of these beaches is essential to the survival and recovery of these three species.
Displays and Activities in the BICSTC has led efforts to increase awareness and support for the Carr Refuge by distributing educational materials, generating media attention about the Refuge, conducting guided sea turtle walks and giving presentations to local groups and schools. While these efforts have been effective, STC's ability to sustain broad outreach programs in the Carr Refuge has been limited without a permanent educational facility located within the Refuge itself. The new Barrier Island Center will greatly improve outreach capabilities in the area.
As the Carr Refuge has demonstrated, people can live and play on important sea turtle nesting beaches without significantly affecting nesting success. But it requires a well informed public that is committed to behaving in a manner that doesn't harm nesting turtles or their nests. As the human population on Brevard County's coast continues to grow, STC and the Barrier Island Center will play an increasingly important role Displays and Activities in the BIC in protecting the fragile barrier island and its globally important sea turtle nesting beaches.
The Barrier Island Center is a focal point for the Archie Carr National Wildlife Refuge and the associated barrier island by providing exhibit space, a presentation hall, a small research library and ongoing educational programs that promote stewardship of the area's fragile natural resources. The Barrier Island Center hosts visiting school groups from throughout Brevard County, as well as local residents and tourists. The facility, its gift shop and its exhibits are open to the public.
The Barrier Island Center would not have been possible without the generous support of the Richard K. Mellon Foundation. The Mellon Foundation purchased the abandoned "Chuck's Steakhouse" and donated the parcel to Brevard County for the purpose of building and operating an educational facility. The County also owns two adjacent parcels stretching across the narrow barrier island梖rom the Indian River Lagoon to the Atlantic Ocean. The proximity of these adjacent public lands will allow visitors a unique interpretive hiking trail that weaves through a cross section of all the barrier island habitats.
