Quote highlighting oceans as lungs.
"More than half of the world's oxygen is produced by the oceans' flora, which is why they are called the planet's lungs."
— Exploring Society: India and Beyond (NCERT)
Explanation of ocean benefits (water cycle, oxygen, culture, trade).
Without oceans, there would be no rainfall. As a vital part of the water cycle, oceans send rain to the continents. Without this mechanism, the Earth would be a lifeless desert. The oceans also play a crucial role in regulating our global climate.
Explanation of pollution and overfishing.
Scientific studies show that human activity is severely polluting our marine environments. Every year, we throw several million tonnes of plastic waste into the oceans. This pollution physically chokes marine life and introduces toxic disruptions to the entire marine ecosystem.

Fill in the blanks on ocean roles and threats.
The oceans play a crucial role in regulating global climate and sustaining life on Earth. In fact, marine flora produces more than half of the world's , which is why the oceans are often called the planet's . Unfortunately, human activity is putting this vital environment under severe threat. Scientific studies show that marine life is currently choking on millions of tonnes of waste thrown into the sea every year. Besides pollution, another massive problem is , which involves excessive harvesting of marine creatures. As a result of these actions, the marine environment is facing a rapid decline. It is our collective responsibility to protect the oceans before the damage becomes irreversible.
