What we do know is that sea turtles live a long time (some can live up to 50 years or more) and have similar lifespans to humans. Most marine turtles take decades to mature—between 20 and 30 years—and remain actively reproductive for another 10 years.
How plastic straws affect the ocean and sea turtles? When plastic straws enter the ocean, they break down into microplastics. These harmful smaller pieces are ingested by birds and marine wildlife unintentionally, and it’s almost impossible to avoid. In fact, a study showed that 100 percent of tested sea turtles had ingested plastic.
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.

Why do sea turtles eat plastic [links]
The Problem: Over 1 million marine animals (including mammals, fish, sharks, turtles, and birds) are killed each year due to plastic debris in the ocean (UNESCO Facts & Figures on Marine Pollution).
As seen in the video of a turtle with a plastic straw in his nose, it’s easy for straws — which are sharper than they look — to injure animals. Besides the choking hazard, this sends animals a false sense of having a full stomach, leading them to die of starvation. more
How does plastic affect marine life

Are plastic straws really killing sea turtles? In 2011, the National Oceanic Atmospheric Association found that plastic debris accumulates pollutants such as PCBs up to 100,000 to 1,000,000 times the levels found in seawater. Marine life, including sea turtles, can be harmed by ingesting plastic straws and brokendown plastic polluting our ocean and waterways.
Plastic bags are petroleum-based and do not biodegrade. Sea turtles and other marine creatures mistake plastics and other garbage as food (such as jellyfish) and ingest it. This mistake causes blockages within their digestive system and eventual death. [links]

Turtles smell well, both on land and under the water. They don't have nostrils, they have bumps under their chins. These bumps, called barbels, have nerves that allow them to pick up scents. In a land turtle, this well-developed sense helps avoid predators. During mating season, sea turtles use their sense of smell to pick up on the pheromones coming from female turtles. here
Turtles taste, see, smell and feel. They have some hearing, but they don't hear well because of something they lack. That doesn’t stop them from moving around and doing everything they need to do to survive, thrive and avoid all those cars whizzing down the road. Because they can’t hear very well, those other senses are a little more finely developed.
While the skin of a turtle is leathery, it is still very sensitive. Tame turtles might enjoy receiving a neck rub, for instance. Sea turtles can feel your hand on their shells -- a series of nerves under the surfaces of their shells enable them to know when you are touching their shells. [links]
Turtles don't hear well because they lack the ear drum or tympanum that other species have. This doesn’t stop them from being able to pick up lower or deeper sound frequencies and vibrations, both in the water and on land. Meanwhile, the organs in a turtle’s ears do help them: They help them to feel changes in water pressure that can warn them of the presence of predators. here
Turtles have well-developed sight. Sea turtles can easily adapt their sharp vision from water to land, enabling them to find food for both themselves and their young. Interestingly, sea turtles can see in color -- this ability helps them to avoid predators and distinguish what foods they are going to eat. The turtle’s sight is so well-developed, he is able to distinguish pattern and shape differences. Despite being able to see well enough to detect patterns, turtles don’t have peripheral vision. here
