Oxygen in the oceans has dropped by two % in the last forty years. The other aspect that is affecting us, to nate, is acidity. We can't grow oysters here any more. And we think of oxygen in the atmosphere as as a constant number. But remember that in water, it's the whole different situation,. That water doesn't mix.
On this episode, we meet with author and paleobiologist Peter Ward.
Ward helps us catalogue the various risks facing Earth’s oceans, how the Atlantic Ocean’s currents are slowing due to warming, what happened in Earths history when ocean currents stopped, and why a reduction in elephant poaching is contributing to the destruction of coral reefs.
