People treat flimsy packaging as trash and heavier packaging as having value. A University of Georgia marketing study found that lightweight plastic bottles and cardboard boxes were up to 92% more likely to end up in landfill than sturdier versions. Over the past two decades manufacturers have thinned bottles and lightened packaging to cut cost and waste, and shoppers accepted it at the till. But the researchers found the feel of an item signals its worth, and we are reluctant to discard things that seem useful, even if we never reuse them. A light, crinkly bottle simply feels like rubbish already.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
