The ocean produces half of the planet’s oxygen.

The ocean produces at least 50% of the planet’s oxygen, it is home to most of earth’s biodiversity.

When we burn fossil fuels, we don’t pollute just the air but the oceans, too. Indeed, today’s seas absorb approximately 26% of the CO2 added to the atmosphere (22 million tons per day) from human activities each year which changes the pH of surface waters and leads to acidification.

This problem is rapidly worsening—oceans are now Planet’s Oxygen acidifying faster than they have in some 300 million years. Business as usual scenarios for CO2 emissions could make the ocean up to 150% more acidic by 2100.

Ocean acidification may render most regions of the ocean inhospitable to coral reefs, affecting tourism, food security, shoreline protection, and biodiversity. And for sure could worsen the impact on climate change.
