Question

Using the Everglades example, explain how changing the water flow affected the birds' habitat and their population make it easy and short

Answer 1

Everglades — simple cause and effect

- What changed: canals, levees and drainage altered the natural slow sheet‑flow of water (less water, wrong places and wrong times).
- Habitat effect: marshes dried or flooded at the wrong times, reducing shallow feeding areas, aquatic plants, fish and insects.
- Bird effect: wading birds (herons, egrets, wood storks) had fewer food and nesting sites, so fewer chicks survived and populations fell.
- Bottom line: changing water flow destroyed the conditions birds need to feed and breed; restoring natural flow helps them recover.
