Emptying our Oceans
Greenpeace and KFEM (Korean Federation for Environmental Movement) activists display a huge banner across the beach in Busan reading SOS TUNA.
Many marine ecologists think that the biggest single threat to marine ecosystems today is overfishing. Our appetite for fish is exceeding the oceans' ecological limits with devastating impacts and there is now estimated to be four times more global fishing capacity than there are fish left to catch. Giant ships are now using state of the-art sonar to pinpoint schools of fish quickly and accurately. These ships also have fish processing and packing plants, huge freezing systems, fishmeal processing plants, and powerful engines to drag enormous fishing gear through the ocean.
Causes? Destructive fishing methods
Overfishing doesn't only threaten the fish species we target for food. Other species - such as marine mammals and seabirds - are caught incidentally in fishing gear and killed. This is known in the trade by the innocuous sounding word 'bycatch'. Even worse, many - if not most - modern fishing methods are seriously destructive. Bottom trawling, for example, can destroy entire habitats found on the ocean floor.
What you can do?- Sustainable Seafood
If your supermarket, fishmonger or restaurant does not have a good policy on sourcing sustainable seafood, you will need to do the hard work yourself. Asking questions about your seafood sends a clear message to supermarkets and restaurants that people do care where their seafood comes from.
