"Boxed Water is Better, an upstart company based in Grand Rapids, Michigan, is trying to think inside the box to address the ecological concerns presented by the bottled-water industry. The company seals carbon-filtered water in cartons not unlike those you might find your milk or orange juice in. The packaging itself is, at first glance, quite impressive. Any given Boxed Water carton is made from 76 percent renewable resources-meaning trees-that come from well-managed forests, according to the company. Before filling they are shipped flat to cut down on transportation waste. Cartons are even recyclable, but not all recycling facilities are able to handle them."

a good example of prime numbers in nature -- and why they are important, e.g., for a kind of cicada which has a 13-year cycle... "Because 13 and 17 are both indivisible this gives the cicadas an evolutionary advantage as primes are helpful in avoiding other animals with periodic behaviour. Suppose for example that a predator appears every six years in the forest. Then a cicada with an eight or nine-year life cycle will coincide with the predator much more often than a cicada with a seven-year prime life cycle. These insects are tapping into the code of mathematics for their survival. The cicadas unwittingly discovered the primes using evolutionary tactics but humans have understood that these numbers not just the key to survival but are the very building blocks of the code of mathematics."
