Ensure that you dispose of litter and rubbish responsibly. Many items of wind-blown litter end up in the oceans and plastic bags are often mistaken for food by dolphins and turtles, many of which die after swallowing them. Please make sure you always take litter home with you - ideally recycle any plastic, paper and glass and more importantly cut down on the rubbish you create. If you are visiting the beach please consider taking a rubbish sack and remove any plastic bottles, bags or glass bottles you see along with rope or netting - all can kill marine life.
Dolphins, whales and other marine mammals are affected by heavy metals and PCB's which build up in their blubber. Therefore please use environmentally friendly products where possible to ensure that toxic run off and build ups of harmful chemicals do not affect our rivers and oceans and their inhabitants.
Respect the oceans - enjoy it but take nothing away but memories. Do not buy objects made from coral, shell or other items taken from the sea for "ornamental" reasons or remove these items personally when swimming or diving as this upsets the marine ecosystem. Take care when snorkelling or diving - ensure you do not unintentionally damage coral with fins or by standing on the coral beds.
