Climate change threatens our oceans more than ever before — here’s what you can do to help
Oceans make up over 70% of the Earth’s surface, giving rise to the name Blue Planet. Oceans hold about 96.5% of all water on Earth and cover 70% of the planet’s surface. Despite its enormity, our oceans are fragile, home to delicate ecosystems and vulnerable species.
And today, they are risk — and climate change is to blame.
Oceans absorb about 93% of heat from greenhouse gases and 30% of total carbon dioxide emissions. As these increase, our oceans become hotter and more acidic, which causes coral reefs to die, nutrients to disappear (in turn reducing the number of fish) and forces species to move to cooler waters.
