On 20 December 2013, the UN General Assembly 68th Session proclaimed 2015 as the International Year of Light and Light-based Technologies (IYL 2015). The UN focus is related particularly to light based technologies, communication and energy, but because almost all life depends ultimately on light it is appropriate to emphasise the biological importance of light. Some bacteria living in unusual and hostile environments like geothermal vents on the ocean floor utilize chemicals as an energy source. They however represent a tiny fraction of the life that reaches every part of Earth.
Light is the energy that converts inorganic compounds into the building blocks of life. It allows vision and all that sight makes possible. Most animals rely on vision to seek food and avoid danger. Night and day are the rhythm of our lives and day length the cue for preparing for the changing season for both plants and animals. It is not surprising that the ancients worshipped the sun, it is the key to life as we know it.
