虽然夏天即将结束，但现在收拾好装备，去户外探险还为时不晚。不知道该去哪里？那就去美国看看63个国家公园吧！1916年的今天，时任美国总统伍德罗·威尔逊签署《国家公园管理局组织法》，正式成立国家公园管理局，旨在“保护自然景观、野生动植物和历史遗迹，在供人们休闲娱乐的同时，不得破坏这些场所，并将之传诸后代”。无论是哪里的美景，只有小心呵护才能让这份美丽得以延续。

National Park Service anniversary

Though summer is winding down, it's not too late to pack some gear and head into the great outdoors. Unsure where to go? Look no further than our 63 national parks, which exist thanks to the National Park Service, created on this day in 1916 by President Woodrow Wilson. He ordered the service to preserve the landscape, wildlife, and history of the parks 'in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.' In other words, the park service was established for all of us! Just make sure that whether you're visiting the islands of American Samoa, the glaciers of the North Cascades, the waterways of the Everglades, or the 308-foot Lower Falls of Yellowstone in today's image, that you explore them with care and appreciation so that they can be preserved for centuries to come.
