Fishing

Once, people who lived near lakes, rivers and the sea often depended on fishing for much of their food. Today, most small fishermen who just catch enough fish for themselves with some left over to sell locally, have lost their jobs. Why? Because humans always want more and more of everything. They’ve built big ships which can catch millions of fish in just a few days so there aren’t enough left to breed and make baby fish. No baby fish means no new adult fish… which soon means no fish at all! And because of the pollution from chemicals from farming and factories – which gets into the rivers and then the seas – many fish are either not able to breed or contain so much pollution themselves that they are not good to eat any more. This is very sad because fish are yummy and the oily ones are very healthy for people and penguins to eat… or were.

I've made another guide all about pollution. Take a look to find out what's going on.

Some people have found that they can farm fish too. This seems like a good idea until you find that they too use poisons on the fish to stop diseases which only start because the fish are kept close together in tanks or floating net cages in the sea.

Of course, not everything that comes out of the sea is a fish. People catch lots of animals like squids (I like those!) and octopuses, shellfish, crabs and lobsters. Some people farm prawns in big open ponds along tropical coasts, once protected by mangrove trees. The ponds for the prawns meant the mangroves were destroyed. This can be very bad because when big storms happen, the coast isn’t protected any more.
