I liked how you gave all your references but mostly the salt concentration affecting dissolved oxygen was interesting. Though i still don't fully understand Eutrophication.

Thanks allot! Was searching for the awnser why warm water holds less oxygen but found allot more! Thank!!

[Harani]

water = Hydrogen+Oxygen
so when fish "breathe" are they breaking the chemical bonds in water to extract oxygen ( and liberate hydrogen) or are they only ever pulling out free oxygen that is mixed into water ( not part of it)

Great info. The o2 air saturation was not something I'd considered regarding liberating oxygen from water, and didn't know if water could hold addition Oxygen

Very lucid and informative.Great Work. Eutrophication description could not have been better. Hats Off!

The graphics are satisfying af huge props to the editor. I also appreciate the informative video. Thanks <3

This is very well done! a lot of well explained content.

[JC_Deutscher]

The best video EVER! thanks a lot for this chrystal clear explanation

This 5 minute video explained my 4 weeks worth of classes for my environmental engineering class.

What a nice and simple illustration... It helps me much in understanding how those oxygen come in and come out of water... :)

This video will be considered a land mark for our time, in time I promise you, very well done.

How does a non-polar molecule dissolve in a polar dissolvent? Is there some kind of phenomenon with H bridges or another solute?

[dave_manley]

Really well done. I'd like to know though how much of the 'trash' is chemical (fertilizers) or animal waste runoff from agriculture vs. population centers (storm runoff, untreated sewage). The garbage truck image is misleading. I'd guess very little of the 'trash' is what we typically think of as trash: plastic, paper, etc.

Cyanobacteria do not undergo photosynthesis. They make their food chemically (chemosynthesis)
