IMPORTANCE OF DARKNESS
Almost all of us love light,
but have you ever thought that the value of darkness is irreplaceable?
Life must go on with bright
days and dark nights. In today's context, there are no dark nights because if
we feel the closeness of nightfall, we reach quickly for light switch. Too
little darkness means too much artificial light at night.
Artificial lights have many
disadvantages. Research proves that our bodies need darkness to produce the hormone
melatonin, which keeps certain cancers from developing, and our bodies need
darkness for sleep. Sleep disorders have been linked to diabetes, obesity,
cardiovascular diseases, and depression.
Besides human, other species
of the world including, nocturnal and crepuscular species of birds, insects,
mammals, fish and reptiles needs darkness too. The Earth's ecology would
collapse without darkness.
Darkness is a source of an
inspiration too. Many artists such as painter, writer, musicians, etc. have got
inspired to write songs, poems, to paint beautiful historical pictures and so
on. And who knows what this vision of the night sky might inspire in each of
us, in our children or grandchildren?
What I want to convey to all
is not to ever switch on your lights but to use it only when required. Believe
it or not, light pollution has become a problem in the world. In the United
States and Western Europe, the amount of light in the sky increases an average
of about 6% every year. But we will never truly address the problem of light
pollution until we become aware of the irreplaceable value and beauty of the
darkness we are losing.
