Google saves the rhino

Google's motto is "don't be evil" and, in what seems to be a rare occurrence nowadays, it is living up to it.

The Silicon Valley giant has given a $5m grant to the World Wildlife Fund to help develop unmanned trackers to catch and deter poachers across the world.

The WWF - the ones with the panda logo, not the wrestlers - already has schemes in Nepal which enables these drones to fly around for up to an hour and use cameras to detect dodgy characters.

With this funding, it will be able to extend these technologies to Africa and Asia to try and chase away poachers who go after rhinos for their horns and elephants for their tusks.

Nice one Google! Definitely not evil...
