trust in a suspicious world

My bottle of water tastes good, but how can I trust the claim that it was sourced from a mountain spring? It’s reported that nearly 40 percent of bottled water is ordinary tap water. Also, many in the UK and Europe are waking up to the growing probability that their breakfast beef sausage is likely breakfast horsemeat sausage. Tests on meat labeled “beef” have exposed widespread fraud in the food industry as horse DNA has been identified. Stories like these breed cynicism, fear, and mistrust.
