How do volcanic eruptions affect the environment?

    Volcanic eruptions are damaging to the environment for the most part, due to the contaminants released into the atmosphere.  Carbon dioxide is released, which is a greenhouse gas thought to contribute to global warming.  Some toxic gases may be harmful to the surrounding wildlife.  

    However, a volcanic eruption may cool the Earth’s surface because the sulphate aerosols that are formed reflect solar radiation.

    It’s believed that an eruption from the Toba super volcano on Sumatra nearly caused humanity to go extinct 73,000 years ago.  The massive amount of volcanic ash spewed into the sky led to a decade long “volcanic winter,” resulting global cooling and subsequent disruptions to ecosystems worldwide that brought the human population down to 10,000 individuals.

    Volcanic eruptions thow out several substances locked up into the earth’s crust to the atmosphere. Some of these substances favour the environment while some are inimical to it. Consider the substances such as Carbon, dioxide, carbon monoxide, Sulphur, ashes, and some minerals that help plants growth.
