Life on earth greatly depends on sunlight. Plants use sunlight energy to create their own food. It is then stored as energy in the plants and is then passed on to consumers when they consume the plants. This builds the foundation for the food chains in our ecosystems and sustains life. So, we now know how important sunlight energy is to life on earth. Other forms of light however, were discovered many years ago by famous scientists which ultimately made life easier with their discoveries such as electricity, traffic lights, light bulbs, cameras etc. We use artificial light every day, in our homes, in buildings, schools, vehicles, for television and computers, and the list goes on.
