A Grain of Rice
Tiny but responsible for feeding half the planet/Food & Drinks
A single grain of long-grain white rice weighs roughly 29 milligrams and is about 7 mm long. It's the staple food for more than 3.5 billion people worldwide. The saying 'take it with a grain of rice' doesn't exist, but given how small one is, it probably should.
