Slide 1 - Tekstslide
This lesson is provided by Sea Shepherd. Sea Shepherd was founded in 1977 and is a marine conservation organisation working to protect the oceans and marine wildlife. Sea Shepherd works globally on a range of issues impacting the oceans, running numerous direct action campaigns each year. Sea turtle poaching is one area Sea Shepherd is working on to help stop sea turtles becoming extinct.

Slide 4 - Video
Empty ocean by 2050
Scientists estimate that by 2050 the ocean ecosystem will be on the verge of collapse, empty of fish and marine wildlife, unless urgent action is taken on the issues impacting on the oceans and marine wildlife.
Show this video (2.53min), which explains how important all species are to our planet.

Endangered status of sea turtles.
6 of the 7 species are currently endangered or critically endangered.
• Hawksbill and Kemp’s Ridley - critically endangered.
• Green and Loggerhead – endangered.
• Leatherback and Olive Ridley – vulnerable.

Slide 14 - Tekstslide
Why sea turtles are endangered
There are a number of issues impacting on sea turtles.
These include:
➢ Plastic pollution
➢ Oil spills
➢ Coastal development impacting nesting
➢ Costal development taking away habitat and food.
➢ Climate change.
➢ Entanglement in ALD fishing gear
➢ Bycatch by commercial fishing
➢ Poaching
Today we will be focusing on poaching.

Sea turtle poaching
The main reasons for sea turtle poaching are:
➢ Turtle meat.
➢ Eggs taken for food.
➢ Shells – used to make ornaments and jewellery, often for tourists.

Slide 17 - Tekstslide
Nesting sea turtles
Female turtles come ashore for nesting season, where they lay their eggs on beaches.
Sea turtles are slow moving and spend time digging a nest and laying eggs, then bury the eggs before heading back to sea.
Poachers can wait until the eggs are laid and then kill the turtle.

Nesting sea turtles
Female turtles will use the same beaches to nest on, often where they were born.
Nesting season is also a regular occurrence, so poachers come to know what time of year to watch for sea turtles and the beaches to monitor.

Slide 20 - Tekstslide
Increasing risk of extinction
Poachers are increasing the risk of turtles becoming extinct by only taking female turtles that are reproducing, laying eggs.
They also often take the eggs – killing the next generation of sea turtles.
Only 1 in 1,000 sea turtles survive from the eggs hatched to adulthood.

Where are sea turtles hunted?
Sea turtles are hunted in many places around the world.
Sea Shepherd runs campaigns to protect sea turtles. These have been in: Costa Rica, Nicaragua, Mayotte, Italy, Honduras, Florida (USA), Barbuda, Antigua and Cabo Verde.
Sea Shepherd Case Studies provide additional learning on some of these locations.

Slide 22 - Tekstslide
Protecting sea turtles
How can we protect sea turtles from poachers?
International laws say it is illegal to carry sea turtle parts or products between countries. Thus most poaching is for local purposes only.
CITES - Convention on International Trade of Endangered Species, requires that countries who have signed up to CITES must prohibit any trade in sea turtles or anything made from them.
Individual countries may also have their own laws to protect sea turtles.

Slide 23 - Tekstslide
Patrolling beaches
Conservation groups, like Sea Shepherd and local activists, patrol beaches to protect nesting turtles from poachers.
In high risk areas sea turtle eggs are removed from the nest and are taken to hatcheries where they can be kept safe until they hatch and can then be returned to the ocean.

Some ways you can help include:
➢ Help stop the use of turtle eggs and meat by spreading awareness.
➢ Never purchase products made from turtle shells.
➢ Do not disturb nesting turtles, nests or hatchlings.

Slide 26 - Tekstslide
How do you think you can help protect sea turtles?
Some ways you can help include:
➢ If visiting nesting beaches ensure you remove your beach equipment. Eg. Beach chairs, umbrellas and children’s toys, so turtles can come ashore and hatchlings find their way to the ocean.
➢ Be sure to knock down sandcastles before you leave because they become obstacles for nesting turtles or new hatchlings.
➢ Don’t drive on nesting beaches, so as not to destroy eggs.
