Short answers

15. Example — Flood: Flooding can wash away topsoil, destroy plants, and drown animals. It can change riverbanks and wetlands, spread pollutants and debris from towns into natural areas, and leave layers of silt that alter where plants can grow. Over time floods can also create new habitats like oxbow lakes, but they often cause immediate damage to ecosystems and wildlife.

16. It is important to learn about natural disasters so people can stay safe, reduce damage, protect wildlife and habitats, and help communities recover faster. Knowing what to expect and how to respond lets individuals prepare (evacuate, secure property) and take actions that lessen environmental harm.

17. Ways communities can prepare to protect the environment
- Create and practice emergency plans and evacuation routes.
- Install early warning systems and share clear safety information.
- Restore and preserve natural barriers (wetlands, mangroves, forests) that reduce flooding and storm damage.
- Use building codes and land-use planning to avoid high-risk areas.
- Plant trees and manage forests to reduce wildfire risk (controlled burns, removing excess fuel).
- Set up rapid cleanup and pollution-control plans to prevent contaminants from spreading after a disaster.
- Educate residents about preparedness and how to protect local ecosystems.
