“Cook is among hundreds of fishermen in Grand Manan – an [Canadian] island of about 2,500 people – who have been temporarily banned from fishing after the sighting of a single North Atlantic right whale.
“This is unprecedented,” said Cook, chairman of the Grand Manan Fishermen’s Association’s lobster advisory board. “We’ve never seen this before, and hopefully we never see it again.”” https://www.theguardian.com/environment/2018/jul/06/canada-grand-manan-ban-fishing-endangered-whale
A lobster advised him not to worry: keep overfishing and destroying habitat and the few hundred right whales will soon be none left whales.
“A spokesman for [SEPA] said: ‘Our officers are comfortable that there is no environmental risk to the River Cree as a result of the bottles being released and, following inquiries, understand almost all of the bottles were contained and removed from the river fairly quickly by local residents.’ …
‘It was never my intent to harm the environment. It was more accident, naivety as well as stupidity in the execution. … It was just my intention to send a wee love bottle with a message to someone I had not yet met.'” http://www.bbc.co.uk/news/uk-scotland-south-scotland-40738484
