1. The lack of clean water can affect people's lives because people use water for everyday things. If people do not shower with clean water, then what is the point of showering at all? Also, people use water to cook, so if people are using dirty water then you could get sick. Some people do not buy water, so you would have to boil the water each time you want to drink it. This is how a lack of clean water could affect people's lives.

2. There are many things that could change people's lives positevly. For example, if you move to a new state where it is warmer. If you go to a new school you could make new friends. Also, somebody new could move in down the street and you could have more friends. Even something as small as eating your favorite meal for dinner could change your life. You could remember it as being amazing. These are how changes (small and large) could change somebody's life.
