I would have been 6 ten years ago so I would have been at my grandparents. Because it’s late in the day currently I know 10 years ago it was a Saturday and I was fast asleep in my grandparents old house that I could walk to without a map. I live on an island so that makes things easy. No matter where I was on the island I could find my way home or to my grandparents. I remember what my baby food tasted like from when I was a baby... I have really good memory but also a really good sense of direction.
Hey, I live an hour away from South Padre Island! The nesting is still continuing, and everytime the turtles lay eggs, they block off that part of the beach. When it's time for the baby turtles to go into the sea, everyone gathers around and cheers for them.

Ten years ago, exactly ten years ago. Even the same time of the day. I was in my bedroom, after a "long" day of kindergarten, in my bed probably. I even remember where my bed was back then. 40 sentimeters away from my current bed position. Tho bed was differend. Probably "reading" something or drawing. Or playing. Or praying night prays with my mom. Did I pass?

When do the turtles at South Padre hatch and go in the ocean, or when do the females come to the shore to lay eggs? I live 5 hours away from South Padre Island.

It would have been nice to have also an explanation of how the baby turtles know in which direction the ocean is, and how they know they're supposed to go there..

It’s heartbreakingly lovely how humans can destroy and protect the environment. “...but they’re pretty good at finding their way. Especially if they got a little help” this line made me love humans, but then remembered we were the reason of their decline ourselves. Let’s educate each other to protect God’s creations.

Mexicans are really desperate people. Imagine they will get all turtles eggs to the brink of extinction. Scientist have to bring all eggs to the USA to hatch. Shout out to all mexicans, how could you. Mexico could be a sanctuary of turtles but you destroyed it. What a shame.

Jairo Mora Sandoval (March 22, 1987 – May 31, 2013) was a Costa Rican environmentalist who was murdered while attempting to protect sea turtle nests and eggs from poaching activity. Just before midnight on May 30, 2013, Mora and four female volunteers were abducted by a group of masked men. The women eventually escaped and informed the police. Mora's bound and beaten body was found on the beach the next morning. An autopsy determined he died by asphyxiation after suffering a blow to the head. No arrests were made by the Costa Rican authorities. The Costa Rican "authorities" were probably in on the poaching and making money to turn a blind eye. Five police officers were on beach duty the night of Mora's murder, and they had been in radio contact with him about an hour before his death. The police were present to increase "the number of eyes and ears on the beach". The Judicial Investigation Police later stated they are "unable to determine a motive for Mora's death."
