These anchorages are located in sensitive marine ecosystems. Their large anchor chains scour the seabed disrupting fish habitat and countless species of plant and animal life. This impacts the entire marine food chain, right up to the endangered Southern Resident Killer Whales.
Ships up to 300 metres long anchor in quiet, rural, residential neighbourhoods. Their large diesel generators run 24/7, polluting the local air shed and causing noise pollution day and night. They also require super bright lighting systems which affects both humans and animal life at night.
Worst of all is the possibility of a ship grounding in the narrow waterways and inlets or colliding with another vessel. Either could result in a catastrophic fuel spill.
