The World’s Parasites Are Going Extinct. Here’s Why That’s a Bad Thing

A parasite, in essence, is any organism that makes its living off another organism (think bed bugs, leeches, vampire fish and even mistletoe). These freeloaders have been rather successful: up to half of Earth’s 7.7 million known species are parasitic, and this lifestyle has evolved independently hundreds of times.
