How Do Volcanoes Effect People?

How do volcanoes effect people?
Volcanoes affect people in many ways, some are good and some are not. Some of the bad ways are that houses, buildings, roads and fields can get covered with ash. As long as you can get the ash off (especially if it is wet), your house may not collapse, but often people leave because of the ash and are not around to continually clean off their roofs. If the ash fall is really heavy it can make it impossible to breathe.

The good part of volcanoes
The main good effect that volcanoes have on the environment is to provide nutrients to the surrounding soil. Volcanic ash often contains minerals that are beneficial to plants, and if it is very fine ash it is able to break down quickly and get mixed into the soil.
