Cacti Needles

The Cacti Needles discovery can be made by playing the Inspect card on a cactus. This will allow humans to avoid cacti; if this isn't discovered a human will die after coming contact with a cactus and they will learn to avoid them on their own after that incident.

The discovery of Cacti Needles can be made with 40 IQ and will increase the IQ of humanity by 3.
