There's a small worm called Loa Loa Filariasis. This parasite can survive in one environment exclusively- namely, underneath the skin and inside the eyes of human beings. Children and the elderly in tropical regions (usually the poorest) are the most widely affected. A painful, slow death is virtually certain. The worm can actually live in the host for 17 years before the host finally dies.
David AttenboroughThat people will object very much to seeing a predator killing its prey, and yet, in the news, will accept showing shots of people shooting one another.
David AttenboroughI think we're lucky to be living when we are, because things are going to get worse.
