世界海洋日

海洋覆盖了地球表面70%以上的面积，因此海洋在调节地球气候和生态系统方面发挥着至关重要的作用。这些浩瀚的海洋支撑着巨大的海洋生物生态系统，美丽的座头鲸也在其中。座头鲸因其“唱歌”而闻名，研究认为这可能是一种孤独的表现。好消息是，随着商业捕鲸活动的结束，鲸鱼的数量有所上升，鲸鱼们也就不太需要再唱孤独之歌了。

虽然鲸鱼可能不再孤独，但它们的生存环境仍然受到气候变化和人类活动的威胁。今天是世界海洋日，我们需要思考海洋的重要性以及人类活动会对其产生的负面影响。

World Oceans Day

Oceans cover more than 70% of the Earth's surface, so it's no surprise they play a crucial role in our planet's climate and ecosystem, supporting a huge amount of marine life. Humpback whales, like the one in our homepage image, can be found in all oceans and have among the world’s longest migrations, traveling thousands of miles from tropical breeding grounds to colder waters in search of food. They are also known for their haunting 'songs.' There are many theories about why they sing, but some research suggests it might be a sign of loneliness. The good news is, that a global ban on commercial whaling has seen their numbers increase, so there is less need for whales to feel lonely.

However, whales' aquatic environment is still at risk from climate change and human action. World Oceans Day is held on June 8 to remind us that the oceans are crucial for the survival of all life on Earth, producing at least half of all the planet's oxygen and home to most of its biodiversity, upon which we all depend.
