The world’s oceans regulate climate, support biodiversity and sustain billions of people. Increasingly, they are also carrying the visible effects of environmental pressure.
Oceans absorb much of the excess heat generated by global warming, helping slow atmospheric temperature rise. However, this comes with consequences such as marine heatwaves, changing currents and coral bleaching.
At the same time, pollution, overfishing and acidification are placing additional stress on marine ecosystems.
Scientists warn that these changes can affect food systems, coastal economies and weather patterns far beyond the sea itself.
Marine conservation efforts are expanding, including protected ocean areas and attempts to reduce plastic waste and emissions.
Experts say the future health of oceans will influence not only nature, but global economic and climate stability.
