    Are Hair Products Safe? New Report Finds Cancer-Linked Ingredients

    A new report raises serious concerns about cancer-linked ingredients in some hair products sold in stores like Sally Beauty. Researchers found that many of these products—especially those marketed to Black women and other women of color—may contain chemicals linked to cancer and other health problems. What Did the Researchers Find? Scientists tested hundreds of hair products made for curly, coily, and textured hair. These included things like hair relaxers, straightening creams, conditioners, and styling products. They discovered that many of these products contain toxic chemicals that can release formaldehyde, a substance known to cause cancer. Even when formaldehyde isn’t listed on the label, some ingredients can turn into it when…

    Why AI Data Centers Need So Much Water

    You’ve probably heard how fast artificial intelligence (AI) is growing — things like chatbots, smart apps, and online games all use powerful computers hidden inside data centers. These buildings are full of servers (big, fast computers) that help process all the information we send and get online. But what most people don’t think about is that these huge computer hubs need a LOT of water, and that’s causing real problems in places like Texas, Virginia, California, and Arizona. What Do Data Centers Actually Do? When you send a text, stream a video, ask an AI a question, or post a photo, it doesn’t just float around in the air. That…

    Is the World Running Out of Fresh Water?

    A new report from the United Nations (UN) warns that the world is running out of fresh water. The UN says we’ve entered a time called “water bankruptcy,” which means many places are under extreme water stress. Water stress happens when a community is using almost all the water it has—so there’s very little left to share. This often happens because water isn’t managed well, and climate change makes things worse by bringing longer droughts and less predictable rainfall. Many Big Cities Are Running Out of Fresh Water New research shows that about half of the world’s 100 biggest cities are running out of fresh water. That means places where…

    A Planet Under Pressure: Global Emissions in 2025

    As 2025 wraps up (even though it feels like it just started!), here’s a quick update on global greenhouse gas emissions. Sadly, the news isn’t great—our three biggest heat-trapping gases are still risi Carbon Dioxide (CO2) Emissions CO₂ is one of the main greenhouse gases. Greenhouse gases act like a blanket around Earth, trapping heat. We need some of them to keep the planet warm enough for life, but too much makes Earth heat up too fast. CO₂ comes from burning fossil fuels like coal, oil, and natural gas. It also comes from wildfires and volcanoes. Scientists have been measuring CO₂ since 1958 at the Mauna Loa Observatory in Hawaii.…

    Pods, Sheets, and Hidden Plastics: What’s Really in Your Detergent?

    I try to do the right thing — recycle, reuse, and make choices that are better for the planet. But I’m learning something new every day. Recently, thanks to my friend, Kathleen, I found out that those “eco-friendly” laundry pods and detergent sheets I thought were a smart switch weren’t so green after all. The thin film that makes them “dissolve” in water is actually made of plastic — hidden plastic that doesn’t really disappear. Pods and laundry sheets marketed as eco-friendly aren’t at all! Although that film, called PVA, may look harmless, but it actually adds more microplastics to our waterways—and even our bodies. What Exactly is PVA? PVA,…

    Why Methane Matters: The Short-Lived Gas with a Big Impact

    Since about 2006, methane levels in Earth’s atmosphere have been climbing fast — mostly because of human activities. It is a super-powerful greenhouse gas that traps heat, but it doesn’t last as long in the air as carbon dioxide does. It’s also the second-largest contributor to rising global temperatures after carbon dioxide (CO₂). It’s already added about half a degree Celsius of global warming since the late 1800s. To keep global warming within the limits of the Paris Agreement, we have to cut methane emissions quickly and deeply. Natural sources like wetlands are hard to control, so the biggest opportunity is reducing this human-made (anthropogenic) greenhouse gas — from things…

    When Plastic Breaks Down, Kids Pay the Price

    Microplastics are tiny pieces of plastic—no bigger than 5 millimeters, about the size of a pencil eraser. They’re everywhere. Each year, people release an estimated 10 to 40 million metric tons into the environment, and if we don’t change our habits, that amount could double by 2040. Most microplastics come from bigger plastic items that slowly break apart, but some are actually made on purpose and added to everyday products like paint, cleaning supplies, toothpaste, plastic-wrapped food, and even baby bottles and shampoo. Plastic may be convenient, but it’s more than just trash on beaches and roads. It can sneak into bodies — especially young ones — in surprising ways.…

    Silicone vs. Plastic: Which Is Really Better?

    Many people think silicone is a good alternative to plastic. I thought so too! I read environmental websites that call silicone, “a healthier choice than plastic” or “beneficial because of its exceptional temperature resistance”. But is it really better than plastic? Silicon is found naturally in the Earth, but it’s hard to get. That’s why silicone products are usually made from something easier to find—silica, which is found in beach sand and quartz. But turning silica into silicon isn’t the end of the process. To make silicone (the stuff used in kitchen tools, baby products, and more), silicon has to be mixed with chemicals made from fossil fuels. So even…

    The Shocking New Threat to Asian Elephants: Skin Poaching

    Let’s face it—when money’s involved, humans often show little or no respect for animals. That’s why poachers are now killing Asian elephants not just for their tusks, but for their skin. It’s a horrifying story—one that brought me to tears while researching and writing—but understanding what’s happening is the first step toward protecting these gentle, endangered giants. Poachers are targeting elephants in places like Myanmar—a known hotspot for the illegal wildlife trade. Instead of focusing only on tusked males, they now kill any elephant they can find—males, females, even babies. Why? Because elephant skin is being sold for jewelry, beads, and traditional medicine.

    The 7 Types of Plastic—and How to Deal with Them

    Do you ever wonder what the numbers inside the triangle on the bottom of plastic containers mean? Those numbers show that not all plastics are the same. In fact, there are 7 types of plastic, and each one is used for different things—and recycled in different ways. Understanding what these numbers mean can help you make smarter choices and keep more plastic out of the ocean and landfills. When you toss plastic into the recycling bin, you probably think it’s being turned into something new—like another bottle or a piece of clothing. But in reality, that’s not usually what happens. Most plastic doesn’t get recycled. In fact, only about 9%…

    The Truth About Fake Grass: It’s Not So Green After All

    When I worked at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, I thought a lot about water—how precious it is here on Earth. Living in drier area, I wanted to save water at home. My front lawn took a lot of it, so I replaced the grass with fake grass, or “artificial turf”. Doing your homework is really important. I tested different types to see which stayed cooler in the sun. I picked one that didn’t get too hot and said it was recyclable. It seemed like a smart, eco-friendly choice. Win-win, right? I didn’t know then what I know now: that fake grass can contain toxic chemicals. That…

    Ocean In Trouble: Toxic Algae Is Killing Sea Life

    Off the coast of Southern California, something heartbreaking is happening for the fourth year in a row. A toxic algae bloom — caused by tiny ocean plants growing out of control — is making sea lions and dolphins sick. Many are getting stranded on beaches, helpless and confused. Some are even dying. This bloom started earlier than usual this year, likely because ocean waters are warmer than normal. Toxic algae produce a dangerous poison called domoic acid. It builds up in fish, and when sea lions and dolphins eat those fish, the poison attacks their brains. Sick animals may seem disoriented, have seizures, or lose their ability to swim and…
