Why Do We Need Light?

Answer

Light has a very vital role in our everyday life. It is used to illuminate objects and to guide our way in the dark. Light is also very essential in transportation as it guides drivers, pilots and sailors as they navigate. Without light from the sun, plants would not be able to manufacture food required for their growth and survival.

We need light just as much as plants do, but for different reasons. One is our internal body clock. Light regulates our internal clock and tells us when it's time to sleep and when it's time to wake up. It also prevents depression and illness. We need light to give us certain vitamins we need.
