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.
Just look at the labels or the bottled water ads: deep, pristine pools of spring water; majestic alpine peaks; healthy, active people gulping down icy bottled water between biking in the park and a trip to the yoga studio. In reality, bottled water is just water. That fact isn't stopping people from buying a lot of it.Estimates variously place worldwide bottled water sales at between $50 and $100 billion each year, with the market expanding at the startling annual rate of 7 percent. Bottled water is big business.But in terms of sustainability, bottled water is a dry well.
