Briseno, director of the United Nations International Strategy for Disaster Reduction, said that in dealing with natural disasters, prevention should be the main thing, rather than passively waiting for the disaster to happen before taking emergency action.

For example, he said that disasters are like diseases. If one always pays attention to one's health, diseases are unlikely to invade. However, it is worrying that despite the timely response of the international community after the disaster, the investment in disaster prevention is far from enough.

He said that if the investment in disaster prevention is doubled, the future return will be several times or even dozens of times.

Briseno emphasized that the important principle of disaster prevention is to respect nature. While establishing some disaster prevention measures, we should consider avoiding triggering another disaster. Protecting wetlands and biodiversity is an ideal way to let nature take its course and prevent disasters.

He explained that the so-called natural disaster is the damage caused by human vulnerability unable to resist natural extreme phenomena. No matter whether it is a volcanic eruption or a tsunami earthquake, if the relevant area is uninhabited, it does not constitute a natural disaster. When an earthquake happens, it is not the earthquake itself that causes the damage, but the death and injury caused by the collapse of buildings.

Therefore, in urban development planning and housing construction, if we try to avoid the potential areas of disasters or take preventive measures as soon as possible, disasters can be completely alleviated.
