poaching and over-exploitation
. They also face habitat destruction and accidental capture—known as bycatch—in fishing gear.

Discarded fishing gear, unattended nets and crab pots
, and commercial fishing practices can entangle and drown turtles.
How many turtles are left?
Recent estimates show us that there are
nearly 6.5 million sea turtles left
in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.
What will happen if turtles are not protected?
If turtles were to ever go extinct,
seagrasses would eventually die off
and this would in turn affect the marine life and eventually human life as well. … With declining turtle population, fewer eggs are deposited and this would result in lesser vegetation and this would cause beach erosion.
Can sea turtles hurt humans?
Answer: Although these aquatic reptiles are not aggressive, they can bite you if they feel danger. Moreover, sea turtles have quite sharp beaks and powerful jaws, so their
bites are usually very painful
. The sea turtle’s bite often creates severe skin bruises and sometimes can break human bones.

On the beach, hatchlings must escape natural predators like birds, crabs, raccoons, and foxes to make it to the sea. Once in the water, hatchlings are consumed by seabirds and fish. Few survive to adulthood, with estimates ranging from
one in 1,000 to one in 10,000

fisheries bycatch, coastal development, pollution and pathogens, direct take, and climate change
.
Where are sea turtles most endangered?

The Pacific leatherbacks
are most at risk of extinction, with both Eastern Pacific and Western Pacific leatherbacks continuing to decline.
