In Japan, scientists cut off cockroaches'wings and put machines in their place to control the insects, which can carry video cameras. The police might use them to watch criminals, or to find people caught under buildings that fall down in earthquakes. Perhaps criminals will control some of the cockroaches, so they can spy on us and come to steal from us. Another idea is to use remote-controlled bees to lead other bees that need pollination. In the future, there may be lots of tiny video cameras carried by insects and birds watching everything we do.
