Plastic is everywhere in our daily life. When you buy something at a convenience store, you will usually find that the container or wrapper is made of plastic. When you feel thirsty, you are likely to buy something to drink in a plastic bottle. Plastic is very convenient, but it is causing serious environmental problems, especially for the oceans.
　As you may know, plastic can be harmful to marine life. For example, plastic pollution is causing harm to sea turtles. Turtles find plastic bags in the ocean and eat them, thinking they are jellyfish. This causes the turtles to suffer and sometimes die.
　However, this is only the tip of the iceberg. Let’s take a closer look at the effects plastics have on our environment and on humans and think about how we can help to conserve nature.
