A Grain of Rice
The tiny seed that feeds half of humanity/Food & Drinks
A single grain of long-grain white rice weighs about 25 milligrams, is about 7 mm long, and contains roughly 300 joules of energy. Rice feeds more than 3.5 billion people daily and has been cultivated for over 10,000 years. There are more than 40,000 varieties of rice. A typical serving contains about 3,500 grains, and global production exceeds 500 million tonnes per year — about 60 kg for every person on Earth.
