A green mineral that can help reverse climate change by naturally removing CO2.
Olivine is transported to nearby beaches and coastlines
Natural wave energy does the rest, breaking down the olivine so it removes CO2
CO2 is captured in the water and in limestone rocks at the bottom of the ocean
More than 99.9% of CO2 on Earth is stored in rock. This occured over billions of years through a process known as the carbonate-silicate cycle.
When rain falls on volcanic rocks and washes them into the ocean, it causes a reaction over long time-scales that removes CO2 from the atmosphere, fixes it into rock. As that rock erodes and trickles down into waterways that eventually trickle into the ocean, it becomes permanently fixed in limestone at the bottom of the ocean.
