Artificial intelligence shows unprecedented detail in global fishing activities

Researchers are learning more than ever before about the effects humans are having on global fish stocks. It's all thanks to a website -- funded in part by actor Leonardo DiCaprio's foundation -- that tracks ships and uses a type of artificial intelligence to figure out incredible detail in worldwide fishing patterns. Kristina Boerder, a PhD student in marine biology at Dalhousie University, is one of the researchers working with Global Fishing Watch and a co-author on a study published this week in the journal Science. She said humans have been fishing for 42,000 years but we've been "rather in the dark" about where and how much fishing activity is happening. "This is really a problem because this is a resource that is not infinite," Boerder told the CBC's Mainstreet.
