Step 1 of 3
- A storm. Big waves roll in from the sea.
- Mangroves slow the waves. Smaller waves reach the houses.
- The mangroves are cut. Bigger waves reach the houses.

Mangroves slow strong winds and waves in storms. Ecosystems also give people clean air, water, food, wood and medicines.

Bees and some other animals carry pollen between flowers. They are pollinators.
Growing one crop again and again is monoculture. It can harm the soil and the pollinators.
