National Geographic Channel will celebrate Earth Day with its first annual photo contest. There will be six days of special earth-themed programming running on the channel from 21- 26 April.

According to an official release, the channel is giving amateur photographers the opportunity to define "Earth Day" through their camera lens. The contest closes on 25 April.

Individuals can submit original photography to the contest for their chance to be selected as one of the top ten contestants to have their work showcased on the National Geographic Channel's Internet Photo Gallery on 1 May. The grand prize winner will be judged on 3 May by Canadian National Geographic photographer Paul Nicklen.

In India the programme airs at 7 pm on Monday.
