The world’s nuclear power plants create large amounts of radioactive waste that must be safely buried in the ground. However, officials worry that such waste can stay radioactive for thousands of years, so how can people warn others about these nuclear waste burial grounds?
Leaving written warnings won’t work since people a thousand years from now likely won’t understand the language, so scientists are thinking about genetically engineering cats to turn green when exposed to radiation. Then spread a legend about the dangers when cats turn green. While far-fetched, it is one way to warn future people about the dangers of radiation, courtesy of cats.
