Pachacha [2.7K]

Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.

Volcanic eruptions have devastating consequences for human populations and lead to destruction as well as societal collapse.

In conclusion, active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.
