Over the past 25 years annual large vessel traffic in the straight of Georgia, (as well as in/out of Port of Vancouver) has increased substantially.  About  11,000 large vessels travel through these waters every year, each one with huge diesel engines producing abundant acoustic energy.  Why has Ecojustie waited till now to get hysterical on the matter?  

Why has Ecojustice not raved and ranted against the thousands of BC ferries sailings in the same waters each year. The Spirit of Vancouver Island ferry has 21,000 hp of propulsion creating thunderous underwater signals.  If their truly is a marine mammal harm issue then it applies to every large vessel, not just oil tankers.
