David Attenborough’s Light on Earth – Trailer 
Sir David Attenborough is about to embark on an exciting adventure— a search for the lights of nature. The journey will lead into ocean depths, to claustrophobic caves, and forests by night. Fireflies are swarming on land, deep-sea anglerfish are swimming in the oceans and fungi are briskly glowing away in our forests. The big mystery is: How and why do organisms produce living lights? Now, for the first time, we can capture the faintest glow of luminous life, using cameras over 4,000 times more sensitive than a decade ago. Bioluminescence is everywhere—in the soil, on land, throughout the oceans.
With. Attenborough at the helm, let there be light!
