>The polar bears and seals photographed by Michio cannot hunt and catch food.

JFYI MIchio is a legendary Japanese photographer. In this context does the phrase "the polar bears and seals" mean "The polar bears and seals in the Arctic Ocean" or "the polar bears and seals which Michio photographed"?

@syh23 [This is a short story about a Japanese photographer, available in the final chapter of an English textbook for 9th graders in Japan.]

Michio tried to show this feeling of freedom and wonder in his photographs. He took playful photographs of polar bears and majestic photographs of Arctic mountains.
In 1996, he was killed by a bear as he camped alone in Kamchatka. "We only have one life to live," wrote Michio. Though his life was cut short, Michio seemed truly happy as a photographer. He loved his work and he loved Alaska.

In Michio's photographs, the beauty of Alaska will stay with us forever. That is the magic of photographs. However, the Alaskan wilderness is changing because of global warming. The Arctic glaciers are melting. ***The polar bears and seals photographed by Michio cannot hunt and catch food.*** The habitat of the caribou is growing smaller. Even the Inuit are losing their traditional way of life.

The Alaskan wilderness was special to Michio. He used his photographs to share it with us, and to show us the importance of life on the Earth. Michio's own life was changed because of one photograph. Perhaps his photographs will also change someone's life. Maybe Michio's Alaskan photographs will encourage us to think about the beautiful Earth we share.

@syh23 Now I got it. THX!
