Planet Earth, often referred to as the "Blue Planet," is a magnificent orb covered by vast oceans that play a vital role in sustaining life. The oceans hold unimaginable wonders, support diverse ecosystems, and regulate the planet's climate. However, the delicate balance of our oceans is being disrupted by various factors, leading to profound changes in the oceanic environments. It is high time we explored the current state of our oceans, the factors driving these changes, and the implications for the future of our planet. Therefore, consolidated global actions are necessary to highlight the changes in oceanic environments and the urgent actions required to save the planet's blue lifeline.
