From Akanksha Singh for JSTOR Daily: “Before ice dispensed at the press of a button or the twist of an ice cube tray, ice was a luxury. An iced drink was indicative of wealth, and the ice industry was a multi-million-dollar employer. Norway—a hub for natural ice—exported one million tons of it per year. The US market overshadowed that effort manifold. At its peak in the nineteenth century, an estimated 90,000 people and 25,000 horses were involved in the natural ice trade in the States. In fact, such was the demand for American ice in London at one point, Lake Oppegård in Norway was rechristened “Wenham Lake” (after a lake in a Massachusetts town) to compete with American ice imports in England. By 1856, American ice was shipped to South America, the Caribbean, Southeast Asia and Australia, the Persian Gulf, and its biggest market–India.”
Why you should stop putting plastic in the microwave
From Celia Ford for Wired: “In a study published in June in Environmental Science & Technology, Kazi Hussain and his colleagues reported that, when microwaved, plastic containers released millions of bits of plastic, called microplastics, and even tinier nanoplastics. Plastics are complex cocktails of long chains of carbon, called polymers, mixed in with chemical additives, small molecules that help mold the polymers into their final shape and imbue them with resistance to oxidation, UV exposure, and other wear and tear. Microwaving delivers a double whammy: heat and hydrolysis, a chemical reaction through which bonds are broken by water molecules. All of these can cause a container to crack and shed tiny bits of itself as microplastics, nanoplastics, and leachates, toxic chemical components of the plastic. The human health effects of plastic exposure are unclear, but scientists have suspected for years that they aren’t good.”
