"Sewage treatment is the process of removing contaminants from wastewater and household sewage, both runoff (effluents), domestic, commercial and institutional. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Using advanced technology it is now possible to re-use sewage effluent for drinking water, although Singapore is the only country to implement such technology on a production scale in its production of NEWater."

"Before the riot of 2001, Cincinnati's overall crime rate was dropping dramatically and had reached its lowest point since 1992. After the riot violent crime increased. Reflecting national trends, crime rates in Cincinnati have dropped in all categories from 2006 to 2010." [Crime in Cincinnati. Wikipedia]

This line graph sample shows the relative price changes for fresh fruits and vegetables, sugars and sweets, and soft drinks, using the period 1982–84 as the baseline (index = 100), 1978–2002. It was designed on the base of line chart from the website of the U.S. National Center for Chronic Disease Prevention and Health Promotion.
"The number of overweight and obese youth has increased in recent decades, yet few data assess how the lives of children have changed during the “obesity epidemic.” ...
Eating as a primary activity declined, suggesting a shift toward snacking or eating as a secondary activity. Statistically significant trends exist for carbohydrate intake, especially for chips/ crackers/ popcorn/ pretzels (intake tripled from the mid-1970s to the mid-1990s) and soft drinks (intake doubled during the same period). Price and income data suggest possible economic reasons for these changes. The percentage of disposable income spent on food has declined continuously, and almost all of the decline has been represented by food consumed at home, yet today’s disposable income buys more calories than it has in the past. Relative prices have encouraged shifts across food types. From a baseline of 100 during 1982–84, the price index for fresh fruit and vegetables increased to 258 by 2002 (far exceeding general inflation), whereas the price index for soft drinks increased only to 126 by 2002 (below general inflation)."
