Maybe we can mitigate this by educating more people about sustainability
Maybe, but this post (and the documentary) indicates that's just not happening in any valid way.
Of course this is in addition to the efforts of the government to regulate natural resources
The governments, as I said in this post and you would see in the documentary, are ineffectual.
As for my library...it's a whole room, many books which I've collected over my lifetime and continue to. It pleases me. Having said that, I applaud anyone who actively seeks information and understanding through books, so well done - I'm sure you'll add to your library over time.
Or maybe penalty could be impose for the violators. Any thoughts on this?
Possibly, but money talks and the law-makers (governments) often benefit from the poor commercial fishing practices (and bribes I guess). In the documentary they talk about some fishermen being stolen and worked as slaves on fishing boats (unable to leave) for years on end...it's all there to see and yet governments do nothing. The overfishing of oceans is there to see, plainly, and no (or ineffective) measures are in place...like protecting only 0.5% of the worlds oceans from commercial fishing. So penalties? Nah, I don't think that'll work. Humans have to learn a lesson, even if it comes through extinction.
