Not quite ready for summer to end? Take a look at these blue ghost fireflies in the Smoky Mountains. A firefly’s light is actually a chemical reaction, and it’s used to attract a mate. Unfortunately, light pollution is starting to make it difficult for these little guys to send signals to each other and partner up. “Every time a species is lost, it's like extinguishing a room full of candles one by one. You might not notice when the first few flames flicker out, but in the end, you're left sitting in darkness,” says biologist Sara Lewis. “I hope we can find a way to keep these bright lights shining.” To learn more about the magic of fireflies, visit go.ted.com/fireflies
