Climate Change
Volcanic eruptions can have an effect on the overall climate of the planet, and historically have been responsible for altering Earth's temperature -- for example, in the years 1783 and 1784. Eruptions release large quantities of carbon dioxide, which traps heat as part of the greenhouse effect, and thus contributes to the gradual rising of Earth's temperature. Volcanic eruptions also release atmospheric haze, as ash and gases full of sulphur released in the eruption end up surrounding the planet. The result is that sunlight is blocked from reaching the planet's surface; this can have the opposite effect of global warming, actually reducing Earth's temperature.
Materials Released
Volcanic eruptions are always dangerous to the surrounding area. A volcano spews materials such as ash and rock over the local vicinity. This ash is spread over nearby forests and settlements by the wind while rocks fall into rivers, blocking them up and choking plant life. The eruption also releases gases, which can be harmful to wildlife and nearby humans.
On Air Travel
With the sheer number of people who travel by air reach year, volcanoes have become a potential annoyance and even a danger to the aviation industry and to those in the air. For example, aircraft can come into contact with dangerous volcanic clouds, which can cause engine failure and substantial damage. Given the risk of such damage to human life, aircraft are typically grounded when volcanic clouds might pose a problem, leading to flight delays.
Loss of Life
The effects of volcanoes can be deadly. The release of materials, including rocks and magma, in an eruption can lead to dangerous mudslides, clouds of toxic gases and floods of lava, all of which can cause fatalities in nearby towns and villages as well as among local flora and fauna. Houses, roads and other infrastructure can also be destroyed, disrupting lives.
Creativity
Volcanoes don't only destroy; they are also a creative force. The gases produced by volcanoes have been shaping Earth's nature for millennia, creating oceans and atmosphere. The results of volcanic eruptions have also created much of the planet's surface, shaping the islands and mountains of Earth's landscape.
