Gisele Bundchen is set to become a TV presenter.

She wrote on Instagram: "I'm excited to be joining season two of @YearsofLiving Dangerously as a correspondent, exploring deforestation and climate change in my beautiful home country of Brazil. The new season will air globally later this year on @NatGeoChannel #Yearsproject #Amazonforest (sic)."

Previous celebrity reporters for 'Years of Living Dangerously' include Jessica Alba and Olivia Munn.

Gisele, who was appointed as a goodwill ambassador for the United Nations Environment Programme (UNEP) in 2009, is a keen environmentalist and has been the face of a number of UN campaigns, and undertaken field missions in Brazil and Kenya.

She previously said: "The environment has always been my passion. Mother Earth is our fundamental life-support system, and by becoming aware and responsible now, we can assist in preserving the planet."

Conservation has always been a passion of the model's and her bio on the UNEP website states: "While growing up in Brazil, Gisele saw the beauty of nature, as well as the destruction of forests and its effects on the surrounding communities. Her involvement with social-environmental causes began years ago when she spent time with an Indian tribe on the Xingu River in the Amazon Rainforest.

"During her visit, Gisele witnessed the problems faced by the tribe due to water pollution and deforestation. After returning home, she called a footwear company, Grendene, that she had been working with for years. She worked with the company to use her flip-flop line to call attention to environmental causes and raise funds to sponsor them, especially forest and water related projects in the Amazon and Atlantic Rainforest."
