Volcanoes:

Why it is good to live near a volcano: 

Farming. Volcanic environments can be good locations for farming. Volcanic deposits are enriched in elements such as magnesium and potassium. When volcanic rock and ash weathers, these elements are released, producing extremely fertile soils.This is good for increasing renewable energy use.An erupting volcano can trigger tsunamis, flash floods, earthquakes, mudflows and rockfalls.

Why it is bad to live near a Volcano:

1.Volcanos can be very dangerous because they can erupt anytime. It is also bad to live near a volcano because it can destroy plants and crops that human eat.
