Seventy percent of our planet is covered by one huge body of seawater﹣the ocean. In 2008, the United Nations recognized(确立) June 8 as World Oceans Day. It's a day to think about the important role that the oceans play in our lives, the dangers that our oceans are facing and the action we can take to protect them.

    The ocean is home to the most of plants and animals on Earth. Plants in the sea provide us with 70 percent of O2 we breathe. The ocean controls our climate (气候), providing heat in winter and cool air in summer. It also provides us with food and medicine. No matter where you live on the planet, no matter how far from the sea, your life is dependent on the ocean.

    The biggest problem facing the ocean at the moment is plastic pollution. Reducing single﹣use plastic, including plastic bags and plastic bottles, has been an important theme for World Oceans Day for a number of years.

    Climate change and rising sea temperatures are also a huge problem. Rising sea temperatures have a direct influence on weather patterns and are seen as partly responsible for an increase in extreme (极端的) weather.

    The day is celebrated in all kinds of ways, including special events on the beach, river clean﹣ups, school activities, art contests and film festivals. You can join in to remind people about the importance of our oceans and to make a difference.
