Water covers 70% of the surface of the Earth, and serves as home to an incredible variety of living organisms. Most of that water is salty, or marine, while some is freshwater, and it is in constant motion through the hydrologic cycle. How can we describe these environments and ecosystems?

Water is so important and common it’s almost like life evolved in the presence of it. But the discovery institute told me that’s just a coincidence. 😂😂😂

Alas, the world's water supply has been contaminated with that killer chemical, Dihydrogen Monoxide.

Hi, really appreciate your content in general, but the lagoon pic (at 7.35 mins) isn’t a natural lagoon. It’s in Pembrokeshire, Wales, UK. It was a slate quarry and when that ended it was blasted to make an inlet to harbour fishing boats. Now it is a swimming spot and has hosted the world cliff diving championships. Not sure it’s an appropriate example? But I may be wrong 😊 thanks

Naturally evolved Estuaries are so important but most are lost to something lesser now. I hope eventually the natural ones will be returned.

Thank you for these fantastic educational videos. I use your videos with my most advanced English students (ages 9 to adult) in Vietnam. They are homework assignments with written or verbal Tests.

Would you say chloride isnt found in 3 states because its bonded to sodium? The oxygen is bound to hydrogen dave. Youd be specific but limit ideas like the black sea makes people float. That excited me.

A meat-eating environmentalist is one hell of an oxymoron if I ever saw one. Animal agriculture is one of the leading causes of species extinction, habitat destruction, and climate change. More so than all transportation combined. Yet those on top, in power, keep harping on fossil fuels. It's easier to buy an electric car than to change eating habits and take responsibility for our actions. A new comprehensive study from Oxford University clearly shows that a vegan diet is the best for the planet (and the non-human animals) The change is simple. Be vegan.

Didn't ask. Not eating grass. Not driving an electric scooter. You worried about someone eating a damn hamburger when the world is under full on attack by Globalists who would kill you in a second if they could. When the global economy completely implodes in a few months exactly as planned you will be glad to get that hamburger.

You know, you don't HAVE to over-complicate literally EVERY phrase. We're not gonna call you an idiot for using the more simple or more commonly used terms, so just stick with those. It makes you sound a little less pretentious which a lot of us admittedly have a problem with.
