Polar bears live on top of Arctic sea ice, where they mate
and raise their young. Excellent swimmers, they hunt
along coastlines mainly for seals but also prey upon
seabirds, walrus, belugas, and narwhals. The world's
largest terrestrial carnivores, these bears are indicators of
the ecosystem’s health. Due to the effects of climate
change, shrinking habitat, and an increase in pollutants
in northern waters, their future is uncertain.
“From the frigid waters of the Arctic, this polar bear
climbed onto an ice floe for a rest before returning to the
hunt for food. Water streamed off the bear as it lumbered
across the frozen stage—and I followed intently through
my viewfinder. While grasping onto a ledge the mighty
predator shook to and fro, sending a spray of water
droplets in all directions.” —EC

“As my primary hobby and creative outlet,
photography allows me to preserve an 'instant
of time' in our constantly changing environment.
I have been very fortunate to travel to a number
of the world’s ecological sanctuaries, giving me
the opportunity to photograph wildlife within
their natural habitats. With the accelerating
rate of endangerment and possible extinction of some species, there
is significant need for change. I feel it is important to use my
photography to inspire others to appreciate the inherent beauty
and wonder of nature and also to expose its plight.”—EC
