Why the Ocean is Important: The ocean is home to many animals and helps keep our planet healthy. It covers over 70% of the Earth and gives us fresh air. The ocean also helps control the weather and gives food for millions of people. Without the ocean, life on Earth would be very different. · Problems: Waste, too much fishing, and pollution(污染) are making the ocean sick. Every year, millions of tons of plastic waste end up in the ocean. This waste can be bad for or even kill animals like fish, dolphins, and sea turtles. Overfishing means that some fish are becoming less and less. Pollution from factories and cars is also making the ocean water dirty. We need to protect the ocean! · What We Can Do: 1. Use less plastic(塑料). Bring your own e bags, bottles, and so on. 2. Join seaside clean-ups. Help pick up waste from the seaside. Every little bit helps! 3. Be kind to ocean animals. Don't buy things made from shells or corals. 4. Tell others to help too! Share what you know about saving the ocean with your friends and family. The more people who help, the better!
