The leatherback sea turtles population is decreasing as listed below
Reasons for decreaseThere are many factors why the leatherback
sea turtles are endangered.The main abiotic factors are:

leatherback sea turtle.They get caught in commercial fishing nets.And loss of their habitats in remote stretches
of sandy beaches.
Biotic factorsHumansThey eat the leatherback sea turtlesThey poach the leatherback sea turtles and
their eggs
Abiotic factorsPlastic and plastic bagsThey mistake plastic for jellyfish and choke
and dieHabitat destructionLoss of habitatNo place for the leatherback sea turtle to
nest NetsThe leatherback sea turtles can caught inside
of them
Leatherback sea turtle mistaking plastic as a
jellyfish
Leatherback sea turtle getting stuck in fishing net
Leatherback sea turtles habitat getting destroyed by oil
Leatherback sea turtle egg getting poached
Conservation methodsSome people invented a TED ( Turtle
Excluder devices) It allows fisherman to still catch the fish but also if a turtle gets stuck they can go through a little hole.
There are a few other conservation ideas and groups that are looking for donated money to get started.
These methods helped to increase the population of leatherback sea turtles. Which will then help fisheries etc.
Why is this important?????
It is important to save the leatherback sea turtle because they don’t do anything to humans we just kill them
They help swimmers not to get stung by poisonous jellyfish and make them go to the hospital or something like that
How do the leatherback sea turtles affect usThey do not harm peopleThey eat jellyfish which eat good fish from
fisheriesThey are the largest reptiles on the earth
They need your help,
OR ELSE
They will join all of the other unlucky animals who got extinct.
Don’t let this happen,
Save the Leatherback sea turtle!!!!
