How can tornadoes and/or thunderstorms impact human, plant, or animal life?

Answers

Answer: Tornadoes effect the environment by destroying buildings and trees. Tornadoes also kill animals, which effects the food chain and disrupts the whole environment. Tornadoes destroy our farms, which means there will be food shortages around the surrounding area. After everything is destroyed, humans have to rebuild. Tornadoes can cause water contamination, which poses a serious problem, as plants, animals and humans are effected by this. Debris can be very dangerous, as it could kill plants and animals very easily. Some trees take over 100 years to grow, so if they are destroyed, they will be hard to replace. Fires may occur after a tornado due to damaged power lines and gas leaks. Fire contributes to global warming by giving off carbon dioxide into the atmosphere. Because of man-made global warming, scientists believe that there will be an increases in tornadoes and other severe weather.
