Coral reefs are magic underwater world that supports maximum marine life. Coral reefs are in a life or death battle with climate change. It's heart breaking, I mean we are losing an entire ecosystem. These dazzling, invaluable ecosystems have been around for thousands of years. But environmental destruction could completely wipe them from the face of the Earth in just a few decades.

Researchers are trying out every tool they can get the hands on from conservation to strengthening corals in the lab to try to toughen reefs up. But with the wall changing at unprecedented speeds, the question remains : can we save coral reefs from climate change? 

Coral reefs are unlike anywhere else on Earth. They're home to mind-blowing biodiversity. They are actually built from tiny animals : coral polyps. Algae live in the polyps' tissues, and provide nutrients to the coral in exchange for protection. But this delicate teamwork is under threat from climate change. Carbon dioxide emissions dissolve in the seas, making waters more acidic and weakening coral skeletons.  And that's not all.

As global temperature soar, coral reefs suffer through ever more frequent and intense ocean heatwaves. Extreme temperatures cause the algae to produce harmful chemicals, promoting the coral polyps to kick them out. Then there is “coral bleaching” where vibrant polyps turn white from heat stress, a process that can eventually prove fatal. And global warming is already driving vast bleaching events today.

Reefs provide everything from food to income to those that live alongside them, while supporting the world's oceans for the entire planet's benefit. And reefs also protect when storms hit, corals break up strong waves, safeguarding  low-lying land from destruction. Especially vital as global warming fuels storms that are more and more powerful.

The services that reefs provide are under threat from more than just global warming. Local impacts - whether that's pollution, unsustainable tourism or overfishing are adding to their woes. Over half of the world's reefs have been lost in just a few decades. If we continue like this, these beautiful underwater world will soon be lost. Forever! 

If we don't fight to stop climate change, the fight to save coral reefs is doomed. Not in distant future, but within just a few decades. Coral reefs could be the first ecosystem that can totally lost to the climate crisis.Our environment decisions around the World whether that reducing plastic use, all limiting global warming could make all the difference for the future of the world's reefs.
