Buffy is known for its cruelty-free and environmentally friendly practices. In an industry known for waste, Buffy says, it uses "botanic dyes, biodegradable fabrics and recyclable materials that are home-safe and earth-friendly." When it comes to bedding that's cozy and good for the environment, you really can't go wrong with Buffy.
Many people around the world use rare earth elements, or REE, every day -- without even knowing it since they're hidden in common personal electronics. If you use an iPhone, an REE called lanthanum helps make sure the screen has a vivid color pop, while neodymium and dysprosium are credited for helping the device vibrate, among other uses. In electric cars, magnets, which are used to help power the vehicle, rely heavily on rare earths such as neodymium.

Long before iPhones roll off the assembly lines in Zhengzhou, minerals are pulled from the earth from around the globe, the very first step in an iPhone's life. This is the US's only rare-earth mineral mine. It's located in Mountain Pass, Calif., and was run by Molycorp before it filed for bankruptcy in 2015.
With names like dysprosium, neodymium and praseodymium, rare earth elements aren't exactly household names. But the products they're used in -- including iPhones and Tesla cars -- certainly are.
In smartphones, REEs tend to comprise only a fraction of the device's mass, yet rare earths mining is a massive and lucrative global business. That's partly because of the global ubiquity of high-tech devices like smartphones, which require the minerals' conductive and magnetic properties to help them function at the cutting-edge. Statista estimates the number of smartphone subscriptions globally have exceeded 6 billion, and that number is projected to rise by several hundred million in the coming years.
Perhaps the most important use for the rare earth metal neodymium is in an alloy with iron used to make very strong permanent magnets. This makes it possible to miniaturize many electronic devices, including mobile phones, microphones, loudspeakers and electronic musical instruments. It is also used in electric vehicles and wind turbines.
According to a 2021 report by the International Energy Agency, the world will be unable to combat the climate crisis unless there is a drastic increase in the supply of rare earths as well as other so-called "green metals" (like lithium, copper, and cobalt). These metals, used in smartphones and other consumer electronics, are vital to technologies that are expected to play a key role in tackling the climate crisis like electric vehicles, wind turbines, and other items needed for a clean energy transition. Demand for these elements are surging as countries around the world transition to green energy to help hit climate goals, the report says. 0852c4b9a8
