Here are shortlisted entries to the competition, which showcases the best in environmental photography and film. The best photographs will be showcased at the Royal Geographical Society in London from 23 June to 4 July, and tour UK until November. The winners - chosen from more than 10,000 entries - will be announced on 24 June.

Below is my favourite, entitled 'Fishing net making in Mekong Delta, 2012', shot by a Vietnamese photographer Tuyet Trinh Do. I love the composition and vibrancy of the shot.
