Patrick Aryee's Wild World

In one of the most disturbed ecosystems on Earth-the Great Plains of North America-Patrick explores the intricate web that connects grasses and dung beetles to the grizzly bear.

Patrick is in British Columbia for the annual salmon run-a spectacular migration that ensures the survival of one species, and sustains the entire rainforest ecosystem as well.

Patrick is in Costa Rica to witness the annual mass nesting of sea turtles-and the predatory jaguars that come in for the kill.

In Costa Rica, insect numbers are in decline. And Patrick heads deep into the rainforest to determine the impact of this dramatic population decline.
