Opening• De 8:7 For the LORD your God is bringing you into a good
land, a land of brooks of water, of fountains and springs,flowing forth in valleys and hills,
• Eze 12:19 and say of the people of the land, Thus says theLord GOD concerning the inhabitants of Jerusalem in the landof Israel: They shall eat their bread with fearfulness, anddrink water in dismay, because their land will be stripped ofall it contains, on account of the violence of all those whodwell in it.
• Eze 34:18 Is it not enough for you to feed on the goodpasture, that you must tread down with your feet the rest ofyour pasture; and to drink of clear water, that you must foulthe rest with your feet?
What's in your
water?

Case 2: Cuyahoga River
The Cuyahoga River is located in northeast Ohio. Itbegins its 100-mile journey in Geauga County,then flows south to Cuyahoga Falls where itturns sharply north until it empties into Lake Erie.The river drains 813 square miles of land inportions of six counties. Native Americansreferred to the U-shaped river as the Cuyahogaor "crooked river."Fires plagued the Cuyahogabeginning in 1936 when a spark from a blowtorch ignited floating debris and oils. Fireserupted on the river several more times beforeJune 22, 1969, when a river fire capturednational attention when Time magazinedescribed the Cuyahoga as the river that "oozesrather than flows" and in which a person "doesnot drown but decays." This event helped spuran avalanche of pollution control activitiesresulting in the Clean Water Act, Great LakesWater Quality Agreement , and the creation of thefederal and state Environmental ProtectionAgencies.http://www.epa.gov/glnpo/aoc/cuyahoga.html
