A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on characteristics that distinguish it as a distinct ecosystem. The primary factor that distinguishes wetlands is the characteristic vegetation that is adapted to its unique soil conditions: Wetlands are made up primarily of hydric soil, which supports aquatic plants.
The water found in wetlands can be saltwater, freshwater, or brackish. There are four major kinds of wetlands, swamps, marshes, bogs and fens. Some experts add wet meadows and aquatic systems as added wetland types, although others consider both of these to be simply marsh. In addition, there are many sub-types of wetlands; a few examples include mangrove, carr, pocosin, and varzea.
Wetlands play a number of roles in the environment, principally water purification, flood control, and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life.
William Sanford "Bill" Nye (born November 27, 1955), popularly known as Bill Nye the Science Guy, is an American science educator, comedian, television host, actor, mechanical engineer, and scientist. He is best known as the host of the Disney/PBS children's science show Bill Nye the Science Guy (1993–1998) and for his many subsequent appearances in popular media as a science educator.
William Sanford Nye was born in Washington, D.C., the son of Jacqueline (née Jenkins; c. 1920–2000), a codebreaker during World War II, and Edwin Darby "Ned" Nye (died 1997), also a World War II veteran whose experience in a Japanese prisoner of war camp led him to become a sundial enthusiast. Nye is a fourth-generation Washington, D.C. resident on his father's side of the family. After attending Lafayette Elementary and Alice Deal Junior High in the city, he was accepted to the private Sidwell Friends School on a partial scholarship, graduating in 1973. He studied mechanical engineering at Cornell University, where one of his professors was Carl Sagan, and graduated with a Bachelor of Science in 1977. He was awarded an honorary doctorate by The Johns Hopkins University in May 2008. In May 2011, Nye was awarded an Honorary Doctor of Science degree from Willamette University where he was the keynote speaker for that year's commencement exercises.
Far, where dawn never ends
Away, are echoes the old lady sings
Crying that years
Years I've been trapped in this cave
Inside, a candle consumed by its flame
And all of the repenting words aside
I desire to hurt you
Desert the world you belong to
In the forest where I lay
My hungry heart
My mellow mind
All my thoughts
They're weak in kind
They're dreams
Red is the mountain of mice
Rotten on the hour of demise
The pile, it resembles a crown
And every roaring squel
Is shame in disguise
Coming clear
And all that you wished for
Is becoming right now
Still it stays, in troubling ways
The ire
Far, where dawn never ends
Away, the old lady sings
For years I've been trapped in this cave
