More recently, hybrid car-makers have had programs to take back and safely dispose of used or damaged high-voltage battery packs for 15 years. Those nickel-metal-hydride cells contain precious metals with a known recycling value.
The term secular stagnation was originally coined by Alvin Hansen in 1938 to describe what he feared was the fate of the American economy following the Great Depression of the early 1930s: a check to economic progress as investment opportunities were stunted by the closing of the frontier and the collapse of immigration.
Hibernation is when an animal goes to rest for the winter season to stay warm. Not all animals hibernate. Hibernating results in a deep sleep over a period of time that limit â¦ s bodily functions. Many forest animals such as bears, deer, owls, and other warm blooded animals stock up on fat by eating tremendous amounts of food. Once they have enough body fat to keep warm and survive during the winter season, they hibernate. Only one animal is known to actually go into a deep sleep and not hibernate, the grizzly bear - its bodily functions do not slow as happens in hibernation, but it has special bidy functions instead. Hibernate means that a animal stocks up on food and then sleeps throughout winter. Hibernation occurs in mammals like bears and squirrels during the winter, where they store food in the fall, and then sleep throughout the entire winter season, and wake up in the spring.
