One third of all sharks caught by shark nets are found on the inside of the net. Shark nets are not as safe as we think! They are also unsafe for marine life, killing thousands of sharks and other marine animals like dolphins, whales, turtles and seals. In our enlightened technological era, it's time for change -- we can't keep contributing to shark and marine animals' deaths. It seems that we don't have to any longer. We take a trip with our new field presenter, Bertus Louw, to investigate a new, sustainable system called the SharkSafe Barrier which might just be the answer. It's based on the brilliant principle of biomimicry. Designed to mimic natural kelp forests, long black tubes are anchored to the sea floor and fitted with magnets that interfere with the sharks sensory glands, deterring them from passing through the barrier. Not only does this barrier deter sharks from entering swimming beaches, it also causes no harm to sharks as well as other marine life. It's time for a change and this new system is an exciting new solution that manages to strike the delicate 50|50 balance between humans and nature.
