Elephants Alert Rangers to Whereabouts Via SMS

I told you August 7 that the USDA and MIT are working together on "virtual fence" technology to manage cow herds. How rangers in Kenya are using something vaguely similar to protect elephants. Local farmers often shoot and kill elephants that raid their farms. So a group called Save the Elephants set up GPS COLLARS OUTFITTED WITH CELL PHONE TEXT MESSAGING capability on them. When elephants are headed for farms, local rangers get a text message that tells where the elephant is going, so they can chase them away.
