How Do Volcanoes Affect Us?
Emit gases such as carbon dioxide and sulphur dioxide
Helps to keep the earth warm
If too much carbon dioxide is produced (i.e. deforestation, burning of fossil fuels),
Might lead to global warming, causing floods/droughts
Sulphur dioxide causes the problem of acid rain
Acid rain corrodes stonework, kills fishes in lakes, etc.
