That is not just the problem of the Philippines in fact if there was not control on fishing in the West oceans would be completely over fished and I might add that those controls are not solving the total problem. Here in the Philipines there are many fishermen that try to survive poverty and feed their families. The normal tradition of eating small fished fresh or dried is embeded deep citizens here want to buy cheap and tasty food and due to their poverty situation are used to living on a daily bases and are more worried about putting enough food on the table to feed their large families. The problem is of course more a population growth thing and growing poverty. Your statement of they just think from nose to mouth is not actually true, they think of daily survival and for many its hard to put just one meal a day on the table. The only people that can stop over fishing are the law makers but it takes money to ensure laws are up held. Effort are being made to control over fishing and illegal fishing but without enough enforcers and funds its become more a case of we are doing what we can.
