What are the positive and negative effects of volcanicity to man?

Volcanicity can have both positive and negative effects on humans. On the positive side, volcanic eruptions can create fertile soils, enhance mineral resources, and contribute to geothermal energy production. Conversely, the negative effects include the destruction of infrastructure, loss of life, and environmental hazards such as ash fallout, lava flows, and toxic gases, which can disrupt communities and ecosystems. Balancing these effects is crucial for sustainable development in volcanic regions.
