城市中心的绿色天堂 'A haven of greenery in the heart of the city
Labor Day is a well-earned day of rest for many workers across America. The food we eat, the shelter over our heads, and the transportation that moves us around all exist thanks to our collective labor. Organized labor movements grew in the 19th century, along with calls for a day to honor workers' contributions. The first Labor Day was celebrated with a parade in New York City in September 1882 and similar events spread throughout the country. In 1894, President Grover Cleveland signed a bill declaring the first Monday in September as Labor Day. Today, Labor Day marks the unofficial end of summer, but let's not forget to take a moment to give thanks for the work we all put in to take care of our communities, our families, and ourselves.
你是否有勇气进入这片茂密的沼泽 Dare to delve into this dense swamp
The Okefenokee Swamp, on the border of Georgia and Florida, is the largest intact freshwater swamp in the US. Its slow-moving blackwaters are stained by tannins from decaying organic matter and this vast ecosystem, covering 700 square miles, is packed with wildlife. Herons, cranes, bitterns, American alligators, turtles, snakes, frogs, and Florida black bears are among creatures who roam the swamp, which is largely protected by the Okefenokee National Wildlife Refuge. In the early years of the 20th century, part of the swamp was logged, and its peat deposits were mined for use as fuel. Remnants of railroad lines can still be seen crossing swamp waterways as well as other equipment dating from its time as a logging area.

Marshland, Gloucester, MA
Lit by bright New England sunshine, this salt marsh shows a strong contrast of color between the sea water and the salt-tolerant grass that grows there. Salt marshes serve as a major contributor to the aquatic food web and a nursery for wildlife, both terrestrial and aquatic.
These marshes are located in Gloucester, Massachusetts, America's oldest seaport. Tourists frequenting this tranquil summer vacation spot enjoy freshly caught delicious seafood, stunning beaches, marshes, museums, and boating. Though Gloucester may have a sleepy, small-town feel, it's only 45 minutes away from the bustling state capital city of Boston. Oh, and it's pronounced 'glosster' unless you're from Massachusetts—then it's 'glosstah.'
When does the tide come in?
From the air, this tract of Mockhorn Island on the Atlantic coast of Virginia's Eastern Shore could pass for gentle farmland. But what you're really looking at is rugged tidal marshland, visible when the tide is out—the rest of the time, much of this area is underwater. Mockhorn is itself part of Virginia's coastal island chain called the Barrier Islands, which run down the east coast of the state from the Maryland-Delaware border for about 70 miles, stretching to the mouth of Chesapeake Bay. The green vegetation you see is grass, although not the kind you'll find in a suburban lawn. Instead, it's saltmarsh cordgrass, a type of perennial deciduous species that grows in wetlands and salt marshes like this one.
The only way to access the tidal channels of Mockhorn Island is by boat, and plenty of kayakers, hunters, and sport fishers are willing to brave the fickle, windy weather to enjoy the island's labyrinth of sloughs, bays, and inlets. The area's also a great destination for bird watchers, as many bird species fly directly overhead while migrating. Historically, the rugged terrain and remote location of the Barrier Islands made them a great place for those running from the authorities—it's said that pirates, including Blackbeard himself, spent time in hiding in the backwaters of this rugged coast.
