As the National Park Service celebrates its 100th anniversary （周年纪念）,President Barack Obama has announced the establishment of one new nationalmonument, and the expansion (扩大) of another. In Maine, more than 87,500 acres offorest will become government-protected parkland for the first time. In Hawaii, anational monument created by President George W. Bush in 2006 will expand toabout 582,578 square miles, four times its current size. 

Obama has now created or enlarged 26 national monuments during hispresidency. As a result, his administration says, Obama has protected more of thenation's land than any other president has. But some residents and officials, in bothMaine and Hawaii, object to the plans. (76) They say their local economies depend onthe use of these areas. 

In establishing this monument, Obama took the side of conservationists ( 自然资源保护者) who want laws to protect wild lands. Creating a national park usuallyrequires the approval of Congress. But a 1906 federal law allows the president toestablish national monuments on his own. 

The land's new status as a monument means that mining and drillingoperations are forbidden there. (77) It may also severely limit activities such aslogging, road-building, and hunting. Some of Maine's politicians who want to protectthe state's logging industries say Obama should not have acted alone. They sayWashington should not tell the states how to use their land, especially when people'sjobs are at stake. Maine politician Susan Collins said the president should havelistened to Maine lawmakers and residents, as well as to the U.S. Congress, beforemaking his decision. 

However, those who support the president's decision say the establishmentof the new monument will lead to new jobs through tourism.
