Floods, hurricanes, and tornadoes can impact ecosystems in both negative and positive ways. Floods spread nutrients and sediments but can also cause pollution from damaged infrastructure. Hurricanes bring sediment and pollution that harm coral reefs and coastal habitats while benefiting others through debris removal. Tornadoes destroy vegetation but allow new species to grow, potentially causing loss of habitat, erosion, and disruption of plant-animal relationships. These extreme events both maintain ecosystems through natural cycles and cause damage, demonstrating nature's balance of creation and destruction.
