Trained Rats Help Clear Landmines in Africa
Rats don’t get a lot of respect but in Africa they are helping to clear landmines. They can quickly locate mines and because they are so small, they aren’t heavy enough to trip the mine. The rats can clear two hundred square meters in 20 minutes. It would take people with metal detectors 5 days to d the same job. The rats spend 6 of their 8 years hunting for mines. The last 2 years they spend in retirement getting fed and cuddled by their handlers.
