Large-scale outbreaks of infectious diseases

El Nino phenomenon

Large-area wilt of plant

Extinction of many animal species

The suspended ashes together with other tiny particles after eruption will cool the earth because it will block the sunlight and absorb the heat from sun. And, the plant need sunlight for photosynthesis. With the much reduction of sunlight, the large-area wilt of plant will happen.

El Nino phenomenon is mainly caused by the self rotation of earth.

Without sunlight, animals will not extinct directly. They may just extinct partly for the lack of food (plant).

No relationship between the ashes and the diseases,
