Think of a typical Caribbean meal, rice and peas, callaloo, plantain, breadfruit, maybe some mango for dessert. All of these plant foods began with green leaves capturing sunlight. Even the chicken or fish you eat rely in the end on plants. The process that links sunlight to food is called photosynthesis.

TIP: Whenever you see green leaves, think: “tiny solar panels” turning light energy into food energy.

EXAMPLE: Sugar cane fields in Barbados, banana plantations in St Lucia and coconut trees on the beach all depend on photosynthesis to grow and produce food.
