Producer Jo Sarsby has selected five sites that help you help the oceans.
WWF www.wwf-uk.org/orca/tips
"This WWF web page suggests different ways in which we as individuals can help save the seas. It's easy to sit back and let governments and fishermen take the blame for the state of the oceans. But even being careful about what fish you buy in your local supermarket, can make a big difference."
Marine Stewardship Council page www.msc.org/
"This page shows that buying fish or fish products with the Marine Stewardship Council (MSC) label will help. When you see the fish with a tick, you know it is good for the environment."
Seafood choices page www.seafoodchoices.com Monterey Bay Ocean Conservation page www.mbayaq.org/
"These two web pages are especially good for viewers in the US. They give detailed information on the sustainability of individual species which are popular in North America. Again, they list some things to be aware of before choosing a particular fish to buy."
WWF Fully Protected Marine Reserves www.panda.org/
"It's good to know that it's not all doom and gloom. There are ways to resolve some of our marine problems. This web site shows how Marine Reserves can help fishes and fisheries."
