Ecology on Khan Academy: Why are polar bears found only in the Arctic? Why does mildew grow in your shower and not (hopefully) in your sock drawer? Learn how ecologists study the interactions between organisms and their environment, and how these interactions affect where, and in what numbers, different types of organisms are found.

There was a film about algae farming as a viable alternative to fossil fuels and yet here we have 'Farms' over a larger spread all over the world!

[@kevjtnbtmglr]

Why not talk about solutions? Or is that next video?

[@rizanasamad3324]

What if it was an anaerobic bacteria that decomposes?

[@fatimazaim503]

Why the algae dies? its on the surface, it has oxygen in contact

[@travisanthony114]

A large source of nitrogen comes from animal agriculture practices, specifically animal waste. Check out 'Cowspiracy' on Netflixs.

[@matwilliams4608]

well all we need to to help the fish to live is pump oxygen in to the water instead of just talking about do it and stop the from dying and keep our fish stock up
