Volcanoes have more positive or negative effects to humanity?

in general

I don't think volcanoes are that dangerous, they only erupt once every 2000years and i read they actually bring a lot of environmental benefits

    They only erupt once every 2000 years???  Where did you get that idea from??

    Try visiting the Big Island of Hawaii.   That Volcano has been in Continuous eruption for the last 30 years.    Go visit the country of Indonesia. The have the most number of active Volcanoes of any country in the world and there are always one of them erupting all the time.   Go visit Italy -  Stromboli is one of the most active volcanoes on Earth and has been erupting almost continuously since 1932. It erupts every 15 Minutes.

    Mostly positive. Volcanic soil, which belongs to a category of soils known as andisols, is derived from both volcanic lava and volcanic ash, both of which are rich in certain key nutrients, such as iron, calcium, magnesium, sodium, potassium, phosphorous, sulfur, silicon and many other trace elements, a rich combination that can act as a stimulant for plant growth. When volcanic ash and lava fall in the same place, particularly if the region receives good amounts of precipitation, this is an ideal situation for rapid regrowth and abundance of plant growth.
