Some of the negative effects are the obvious damages to houses, plants, wildlife, and even people, which are caused by the lava. Also, the gas produced can overcome the oxygen and kill people and animals that way. The positive effects include the
heat, which is an important source of energy. Also, the eruption brings nutrient and minerals to the surface, which is beneficial to plants. One last positive effect is the creation of land forms and igneous rocks, which are used to construct buildings
