After calving, it takes 60 to 90 days for cows to resume cycles. This period is called postpartum anestrous. In first calf heifers, postpartum anestrous lasts longer than mature cows. It normally takes 90 to 120 days for first calf heifers to resume cycles.
The Story of Bottled Water. The Story of Bottled Water, released on March 22, 2010 (World Water Day), employs the Story of Stuff style to tell the story of manufactured demandâhow you get Americans to buy more than half a billion bottles of water every week when it already flows virtually free from the tap.
Eighteen percent of bottled waters do not tell you where their water comes from, and 32 percent do not disclose anything about the treatment or the purity of the water. About 40 percent of bottled water is regular tap water, which may or may not have received any additional treatment. Another independent test performed by the EWG in 2009 revealed 38 low-level contaminants in bottled water, with each of the 10 tested brands containing an average of eight chemicals.
