With all the discussions about protecting the earth and saving the planet, it is easy to forget that we also need to preserve the many species of fish that live in the oceans. In developed countries, much larger quantities of fish are consumed than was the case a century ago when fish only featured on the menu once a week. These days, fish has become a popular healthy alternative to meat and this has created a demand for species such as cod, mackerel and tuna that far outstrips the demands of the previous generation. Throughout the world too, increasing consumption during the past 30 years has meant that the shallow parts of the ocean have been overfished in an effort to supply homes, shops and restaurants with the quantities of fish that they require. Yet despite the sophisticated fishing techniques of today, catches are smaller than they were a century or more ago. What is more, boats are having to drop their nets much deeper into the oceans and the fish they are coming up with are smaller and weigh less than they used to. While government controls have had some effect on fish stocks, the future does not offer a promising picture. Experts predict large-scale extinctions and an irreversibly damaging effect on entire ecosystems, unless greater efforts are made to conserve fish stocks and prevent overfishing in the world’s waters.
