Green tomatoes in a box: how to ripen them indoors

A farmer in a straw hat picks ripe red tomatoes from a wooden crate while a large cardboard box beside him holds a batch of green tomatoes ready for ripening. A circular inset shows the fruits in close-up at different stages of ripeness, from green to pinkish-red. The image clearly explains why unripe tomatoes are best brought to full ripeness at room temperature rather than in the refrigerator.
