A friend of mine sent this link to me earlier today:
This site is well worth a visit. We all know about the pervasive dangers of forgotten land mines, but few seem to know what to do about it. A brilliant if off-beat person has determined that one of the best ways to defuse land mines is to train rats to sniff them out. The rats have a great sense of smell, and they’re light enough not to set off the explosives.
Also, for you graphic artists out there, the website is itself a little gem of brilliance.
