How is the set of living beings and the whole eco system under the water being altered by our activities? Well, it's a question that is frogt in centre in the minds of scientists right now. We don't have a real answer yet about the impact on human health to inhaling or engulfing nanoplastics or microplastics That now appear in the air, in water, in the coffee you drink, in the beer, whatever it is. I mean, i think it's probably safe to say that if you have a choice, you'd rather not be taking in these bits of material that don't exist in nature, but now exist in us.

It’s a well-worn cliché that oceans cover seventy percent of the surface of Earth, but we tend to give them secondary consideration when thinking about the environment. But climate change is wreaking havoc on the oceans, not to mention pollution and overfishing — 90% of the world’s marine fish stocks are fully exploited or depleted. Today’s guest, Sylvia Earle, is a well-known ocean scientist, a celebrated underwater explorer, and a tireless advocate for the world’s oceans. We talk about the current state of our oceans, what we know and have yet to learn about them, and what we can do individually and collectively to make things better.
