The video had been originally uploaded by professional photographer and filmmaker Toby Harriman, who works for the National Geographic Traveler (NatGeo Travel) magazine, on his Instagram account on May 14 and later shared by the magazine’s Instagram page one week ago.

Harriman said he had filmed the video in 2018.

Actor DiCaprio apparently reposted the content, including the caption, from NatGeo Travel’s post as he shared the video on his own account on Friday last week.

“This traditional fishing village in Lan Ha Bay, Vietnam, floats atop emerald waters among lush limestone karst formations,” the caption reads.

“Villagers depend on the sea for survival and make a living from fishing, aquaculture, and tourism.

“It looks like paradise, but their unique way of life is threatened by wastewater, plastic pollution, unsustainable tourist activities, and climate change.”

The caption ended with the advice that visitors to Lan Ha Bay must reduce environmental impact for the bay to remain a beautiful place to live and visit.

As of Tuesday afternoon, DiCaprio’s video post had garnered more than 1.1 million views, over 243,000 likes, and 3,600 comments on Instagram with many users leaving compliments on the bay’s natural beauty.

“Such a gorgeous place. We need to preserve and do what we can to respect it,” a user named misscoeur72 wrote in a comment.

NatGeo Travel’s post has received more than 1.3 million views, over 194,000 likes, and 1,600 comments.

DiCaprio often posts environment-related content on his Instagram and is identified as one of the most active celebrities in the climate change movement.

He established the Leonardo DiCaprio Foundation in 1998, a non-profit organization devoted to promoting environmental awareness.

He has been an active supporter of numerous environmental organizations and sat on the board of the World Wildlife Fund, Global Green USA, and International Fund for Animal Welfare.

In 2014, DiCaprio was appointed a United Nations representative on climate change.

The actor also created, produced, co-wrote and narrated ‘The 11th Hour,’ a documentary about people’s relationship to nature and global warming, which won the Earthwatch Environmental Film Award through the National Geographic Channel in March 2008.

In February 2019, National Geographic ordered a television series adaption of ‘The Right Stuff,’ based on the 1973 book of the same name, with DiCaprio as executive producer.

Lan Ha Bay covers a sea area of more than 7,000 hectares and includes 400 islands.

The bay is dubbed Vietnam’s second Ha Long Bay, which is a UNESCO World Heritage Site and popular travel destination in the northern province of Quang Ninh.
