Through his work, he wants to show the future that faces the Arctic and Antarctic habitats if urgent action isn’t taken. He says that there is life in the ice and that this ice is part of the entire ecosystem that supports artic life, he says: "I call myself an interpreter and a translator". “I translate what the scientists are telling me. If we lose ice, we stand to lose an entire ecosystem. I hope we can realize through my photography how interconnected these species are to ice. It just takes one image to get someone’s attention."
He doesn´t only know of this because of his title as a marine biologist since when he was a child he has lived near the arctic circle and has seen the climate change and how it affects the wildlife.
Nicklen has covered a variety of natural history and conservation issues, from the slaughter of narwhals to the environmental impact of salmon farming to the importance of sea ice and polar ecosystems. He is constantly traveling to find meaningful stories to share and create conscience and public knowledge.

To create this he works in some of Earth’s most remote and extreme environments, where he faces incredible hardships and personal danger, both above and underwater. The result of this is an emotional and shocking image that captures the beauty of the environment where the wildlife lives.
“If you want to shoot the best photography of a particular ecosystem, you have to be comfortable wherever you are,” says Nicklen. “If that’s 150ft deep under the ice, you can’t be sitting there fighting for survival. You need to free up your mind.” Wearing a rebreather to avoid producing bubbles, he stays submerged for up to six hours, submitting himself to the same conditions inhabited by his favorite species. To Nicklen, the Arctic is not a forbidding, alien landscape, but a spiritual home: “I’m far more comfortable around bears than, say, on the streets of New York.”

Start the activity by asking the students if they know what being in danger of extinction is, and if someone doesn't know, then explain. Then ask if someone knows any species of animals in danger of extinction.
After, form small groups and give each group an animal that is in danger of extinction and tell them to investigate about the animal: Where they live, What they eat, what is making them be in danger of extinction and what actions could they do to protect them.
After they finish this project each group will expose their animal and investigation to the class.

In the following TED talk, he talks about his experiences and shows some of his work

- OA 5: observe and identify some native animals that are in danger of extinction, also the deterioration of their habitat, proposing ideas to protect them.
- OA 4: Observe and compare characteristics of different types of habitats, identifying luminosity, humidity, and temperature necessary for the survival of animals that live in it.

- OA 6: Identify and communicate the effects of human activity on animals and their habitats

It can also work in civic education. In 5º grade in OA 22, it says that students have to inform themselves and have opinions about relevant topics in Chile and the world by using news and TIC.
