The so-called disaster

Let's discuss it from the perspectives of disaster-causing factors, disaster-bearing bodies and disasters.

Disaster prevention and mitigation

We must proceed from the principle of disaster itself.

Weaken the intensity or frequency of disaster-causing factors

Enhance the disaster-resistant ability of the disaster-bearing body

Active response after disaster

Reduce the expansion of disasters and the deepening of hazards.

For high school students

Give a specific disaster.

Such as drought, flood, earthquake and so on.

This may be more telling.
