Although out planet gives us life, it can also cause destruction. When the land we live on moves, earthquakes can destroy whole cities. An earthquake in China in 1556 killed more than 830,000 people. When rivers cause floods, large of fields and farmland are often submerged in water. This means people cannot produce enough food to eat, and it leads to famine. A lot of rain can cause landslides, with devastating consequences for villages and towns located on hills or mountains or in valleys below. Too little water is also a serious problem. When almost no rain fell in parts of the U.S. in the early 1930s, the drought forced 2.5 million people to move to other places.
