It can grow up to 30 meters long — as long as three buses! It weighs more than 200 tons. These gentle giants live in all the world’s oceans. Sadly, they are now in danger of extinction. There are only about 10,000 to 25,000 blue whales left in the wild. Why are they in danger? In the past, people hunted blue whales for their oil and meat. Although hunting is now banned, they still face new threats. Plastic pollution fills their ocean home. They often eat plastic by mistake and get sick. Big ships can hit them, causing serious injuries. The noise from ships also makes it hard for them to communicate with each other. Here are three things we can do to help. First, use less plastic. Bring your own water bottle and say no to plastic bags. Second, learn more about blue whales and share what you know with your family and friends. You can draw posters or give a short talk in class. Third, save energy at home and at school. Turning off lights and walking or biking more helps slow down climate change, which warms the oceans. Let’s work together to save the blue whale. Every small action counts. Start today!
