Para. 4 Read for understanding
As you can see, the world beneath the surface of the ocean is indeed an amazing place. On our journey down, we have been fascinated by incredible geological formations as well as unexpected life forms that have become strangely adapted to their extreme environment. With so much of the oceans left to explore, who knows what wonders still await us in the future
We look upwards and wonder what lies beyond our planet. We send probes into the vastness of space to explore the unknown. We build space stations to advance our understanding of the universe. Our curiosity about outer space has remained unshakeable. Meanwhile, it is estimated that more than eighty per cent of the world’s oceans are unexplored. So, if we want to find exciting new life forms as well as undiscovered and unusual geological formations, the ocean is where we should also be looking. Then why don’t we dive to the bottom of a really deep ocean and take a long, close look beneath the waves

Application
As World Oceans Day approaches, we are reminded once again of the importance of the ocean. Not only is the ocean home to an abundance of life, but it also plays an indispensable role in maintaining the balance of the global ecosystem.
However, human activities are putting the ocean at risk. It’s high time that we took action to protect our oceans. Switching to a greener lifestyle is the first step towards ensuring sustainable development for the ocean. Besides, adopting measures to rid the ocean of plastic garbage should be a global priority. On top of that, we students should take advantage of every opportunity to raise public awareness of marine conservation.
Together, we can make a difference and ensure the health of our oceans for years to come.
