On 18 February, we marked World Pangolin Day, which celebrates one of the planet's most bizarre - and endangered - species.

For World Environment Day on 5 June, UN Environment's Goodwill Ambassadors Don Cheadle and Gisele Bünchen shared their favourite spots in nature and encouraged everyone to share the natural places that matter to them.

Mercury has devastating effects on human health and the environment. In September, countries united to adopt the Minamata Convention on Mercury to eliminate the use of the toxic substance in every corner of the world.
6. Lewis Pugh: swimming the message across
In November, Lewis Pugh, UN Environment Patron of the Oceans, became the first person to complete a long-distance swim in the waters of South Georgia. His pioneering swim was made to urge leaders to grant full environmental protection for the Scotia Sea surrounding South Georgia and the South Sandwich Islands, one of the world's biodiversity hotspots.
7. Champions of the Earth gala dinner
In December, we honoured seven new Champions of the Earth and celebrated the inaugural class of Young Champions. The gala evening was hosted by UN Environment Goodwill Ambassadors Dia Mirza and Ellie Goulding.
