Pollination & Pollinator Decline
Explain the importance of insect pollination for plant reproduction and human food security, and discuss the consequences of pollinator decline
What a learner can do afterwards
- Explains why many food crops depend on insect pollination to produce fruit and seeds
- Names examples of crops that require insect pollination (e.g. apples, almonds, oilseed rape)
- Discusses the potential impact of bee population decline on food production
- Connects to plant reproduction — flowers are adapted to attract specific pollinators
The lesson
You already know that insects like bees carry pollen from flower to flower so plants can make seeds. Here's why that matters at breakfast: a huge share of the fruits, nuts, and vegetables you eat only grow because an insect visited their flowers first.
Almond trees in California flower for only a few weeks each spring. There aren't enough wild bees nearby to visit every blossom, so growers truck in millions of honeybee hives just for that short window. Without those bees, most blossoms would never become almonds.
If you want to guess which foods might get scarce first when bees decline, ask: could this plant make its fruit or seed without an insect visit? If the answer is no, that food is at risk.
Many fruits, nuts, and vegetables only form after an insect carries pollen to their flowers, so fewer bees can mean less of that food on the shelf.
