Our Oceans, Our Responsibility
June 8th was officially named by the UN in 2009 as World Oceans Day. It was set up to raise awareness of protecting the oceans, which play a crucial part in global ecosystem. Without the oceans, no living things would survive, humans included.
As senior students, we can protect oceans in our own way. First, try every means to fight against global warming, which has become a great threat to sea creatures. Second, when surfing or boating, never drop litter into the sea. In addition, take an active part in the voluntary activities launched by the ocean organizations.
Every little effort counts. As long as we try our best, we will make a difference to the marine environment.
Watch the video Protecting Biodiversity and answer the questions.
