							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.

							all the things around us reflect light including the human body.This reflection enables us to see things around us. If we don`t have light around us, we might not see things around us like it happens at night . Therefore we need light around us to see things. Light also can be used as a source of energy,i.e. solar energy

							Light is very important as it enables us to see things around us.
All living beings require light for their proper functioning. Imagine if their is no sun, we will have vitamin D deficiency. Apart from humans plants will also get affected as they depend upon light for preparing their food. As animals depend upon plants for food they will also starve to death. The whole food chain will be destroyed. And also many diseases will spread like due to deficiency of vitamin D.
