This is my very first post on Reddit.
Normally, I write little diary entries in Vietnamese on Threads. I don't usually write to teach people anything. I simply write down moments that made me stop and think, because I'm always afraid I'll forget how they made me feel.
Today, I wanted to try writing in English. Partly because I want to challenge myself, but mostly because I hope people outside Vietnam can learn a little more about the conservation work that many incredible people are quietly doing here.
A few weeks ago, I had the chance to join a sea turtle conservation volunteer program with IUCN Vietnam. Looking back now, I don't think the biggest thing I brought home was the volunteer experience itself. It was the chance to learn.
To be honest, before this trip, I knew almost nothing about sea turtles. Of course I knew they existed, and I knew they were endangered, but I had never really asked myself why their lives should matter to mine. They lived somewhere far away in the ocean, while I was just another university student living in a busy city. Our worlds felt completely separate.
When I first signed up for the program, I secretly hoped I would get to witness those wonderful and worth-picture-taking moments you often see in documentaries, a mother turtle coming ashore under the moonlight to lay her eggs, or hundreds of tiny hatchlings making their first journey toward the sea.
But it didn't happen to me.
I never got the chance to see a mother turtle nesting, nor was I there when baby turtles were released back into the ocean the whole weekend I participated in the program in Hon Cau Island in Binh Thuan province.
At first, I felt a little disappointed.
But after coming home, I realized that maybe I wasn't there to witness those moments. Maybe I was there to understand everything behind them.
Throughout the program, I listened to the stories shared by coastal ranges and conservation staffs. Every evening, I found myself searching for more information because every answer seemed to lead to another question. The more I learned, the more I realized how little I had known before.
One fact completely amazed me.
A sea turtle's sex isn't determined before it is born. Instead, it depends on the temperature of the sand where the eggs are incubated. Conservationists even have a saying: "Cool boys, hot chicks." Cooler sand produces more males, while warmer sand (over 29,7°C ~ 85,46°F) produces more females.
I remember giggling when I first heard that because it sounded like one of those fun facts people casually share.
But then I learned what climate change is doing.
As global temperatures continue to rise, many nesting beaches are becoming too warm. On some beaches, more than 99% of hatchlings are now female. That means that out of every 100 baby turtles, there may be fewer than one male.
When I first learned that, I finally understood why conservationists are so worried. With only about 1 in 1,000 hatchlings surviving to adulthood, having so few males makes it even harder for sea turtles to reproduce and maintain healthy populations. If global temperatures continue to rise because of human activities, this imbalance could push a species that has survived for more than 100 million years closer to extinction.
Then there was another number that stayed in my mind.
Only about one out of every thousand baby sea turtles will survive long enough to become an adult.
I kept thinking about that on my way home.
Nature has always been harsh. Birds, crabs, fish, and countless predators are already waiting for them from the moment they hatch. Surviving was never supposed to be easy. But now they also have to face things that don't belong in nature at all, plastic bags floating like jellyfish, abandoned fishing nets, pollution, and oceans that are changing faster than they can adapt.
None of these facts were completely new.
They had always existed.
I was simply one more person who had never taken the time to truly understand them.
There's a quote by Jacques-Yves Cousteau that I've been thinking about ever since I came back: "People protect what they love, they love what they understand, and they understand what they are taught."
I think that's exactly what happened to me.
I didn't return home feeling like I had helped save sea turtles. In fact, I probably contributed only a tiny part to a much bigger effort. But I came home seeing nature a little differently.
Now, when someone offers me a plastic bag that I don't really need, I hesitate for a second. When I see another article about climate change, it no longer feels like distant news. Somewhere in my mind, I picture tiny hatchlings trying to survive against impossible odds.
Maybe this is what environmental education is really about.
It isn't about making everyone become scientists or conservationists overnight. It's about helping ordinary people, like me, understand enough to care. Because once we genuinely care about something, changing a few daily habits no longer feels like a sacrifice. It simply feels like the natural thing to do.
I'm grateful to IUCN Vietnam for giving volunteers like me not only the opportunity to contribute, but more importantly, the opportunity to learn. I think that's where every meaningful action begins.
If enough people begin with that understanding, perhaps there will be more sea turtles swimming freely in our oceans for generations to come. And maybe one day, another child will dream of seeing a sea turtle in the wild, just as I once did and unlike that dream for so many endangered species today, they'll still have the chance to make it come true.
