What is an endangered language? The world faces enormous challenges in maintaining language diversity. Of the more than 6,912 languages, half may be in danger of disappearing in the next several decades, although this figure cannot be verified. Endangered languages are languages that are on the brink of extinction, much like endangered species of plants or animals. A language is considered to be endangered when parents are no longer teaching it to their children, and it is no longer being actively used in everyday life. A language is considered to be nearly extinct when it is spoken by only a few elderly native speakers.
Energy exists freely in nature. Some of them exist infinitely (never run out, called RENEWABLE), the rest have finite amounts (they took millions of years to form, and will run out one day, called NON-RENEWABLE). Non-renewable energy is energy from fossil fuels (coal, crude oil, natural gas) and uranium. Fossil fuels are mainly made up of Carbon. It is believed that fossil fuels were formed over 300 million years ago, when the earth was a lot different in its landscape. It had swampy forests and very shallow seas.
