At one time, the river would dry up without the dams, but as hard surfaces channel more water into the river, along with treated wastewater now flowing in, that won't happen anymore. Now the dams just interfere with fish and boaters and degrade the ... Clean water, fewer dams: What's Des Plaines River coming to?

Anthropogenic climate change may not be a recent phenomenon, with researchers reporting ice cores from the first two centuries AD show big spikes in methane prevalence.
Those two centuries, the researchers note, co-incide with the most prosperous periods for the Roman Empire and Han Dynasty.
A Nature paper, Natural and anthropogenic variations in methane sources during the past two millennia, speculates that deforestation and use of charcoal as a fuel made for increases in methane emissions.
The methane was detected in ice cores from Greelanand. The cores also show methane levels tailed off around 200 AD, a time at which deforestation slowed as Rome declined and the Han Dynasty collapsed.
Lead author Celia Sapart of Utrecht University told Reuters the team behind the paper say they have spotted a spike in methane emissions that corresponds roughly to the end of the dark ages, and a dip not longer after the Black Death.
One possible fly in the ointment is a rise in methane prevalence before the Little Ice Age.
Sapart feels the results mean climate scientists need to rethink what is a "normal" state for Earth's climate.
"The pre-industrial time was not a natural time for the climate - it was already influenced by human activity," she told Reuters, adding that "When we do future climate predictions we have to think about what is natural and what did we add." ®

Question by : What does "fish out of water" mean in literature? I have to write a "fish out of water" scene (for a play) in my writing class. What does that mean? Examples? Best answer for What does "fish out of water" mean in literature?:
Answer by Mogo Answer by Kes Answer by Skechers
it just means out of place
A fish out of water is a fish out of its natural element. Perhaps a golfer with club in the middle of a football game would be a "fish out of water" as a simple example. In literature it would mean anyone in a role they are not well suited for and therefore inept.
A fish out of water means someone in a situation they are unsuited to. This metaphor is quite old. Chaucer used a version of it in The Canterbury Tales: Prologue: ...a monk, when he is cloisterless; Is like to a fish that is waterless The earliest reference that I can find to the present day wording of the phrase is in Samuel Purchas's Pilgrimage, 1613: "The Arabians out of the deserts are as Fishes out of the Water."
