A new study finds that arthropods - ants, beetles, mites and other small creatures - eat up tons of garbage on the streets of Manhattan. Literally tons.
"This isn't just a silly fact,"said Elsa Youngsteadt, a research associate at North Carolina State and lead author of a paper on the bugs in Global Change Biology. "This highlights a very real service that these arthropods provide. They effectively dispose of our trash for us."
