Sir David Attenborough is NOT DEAD. The hoax below, which claims that English broadcaster and naturalist has died at the age of 90 at Kings Hospital, London, is another reason why you should always use popular and reputable news websites as your source of information. The website: "www.professionalmac.com," and others like it, where the fake story has been published, are fake-news websites. The fake-websites are considered a threat because some persons are taking the fake articles that they have published as authentic news. Whenever something dramatic or depressing like the death of someone is posted on social networking or unpopular websites please verify it with a reputable news website before posting, sharing, commenting or liking.
