Oscar Aranda, CNN Hero, Safeguards Mexico's Sea Turtles

Along the shores of Mexico's Puerto Vallarta, illegal poachers pose a threat to sea turtles laying their eggs in the sand.

For Oscar Aranda, saving the turtles and their offspring is a mission. Through nightly patrols, Aranda keeps the beaches safe for turtles to lay the eggs, and relocates the unhatched eggs to a protected area.

CNN honored Aranda as a CNN Hero for his efforts to safeguard the endangered turtles.
