Australian fish stock collapsing due to overfishing

While most media usually pay little attention to environmental issues, I was positively surprised to see a television talkshow mention the sensitive topic of overfishing. The short video below, an extract from the 7pm Project on channel 10, highlights the declining fishstocks in Australia (and around the world). UN warns that we might not have any fish to eat by 2050 and that we need to make decisions in the short term to positively affect the long term.
