Envoy: Shark Cull (2021) on Netflix

Plot summary

Queensland and New South Wales in Australia run coastal shark safety programs that set baited drum lines and nets in the water to keep swimmers and surfers safe from sharks. Those methods have been scientifically proven ineffective at protecting people in the sea, leaving swimmers and surfers at risk, and they continue to affect marine ecosystems, including the Great Barrier Reef. The account also follows ocean conservation figures and the group Sea Shepherd as they explore a topic often described as scarcely understood, setting out the importance of sharks in the oceans and tracing the longest marine cull in history.
