How Grizzlies Feed Trees with Salmon I Climate Heroes

↠ Check out our Climate Heroes series: • Climate Heroes
Each fall in North America, the salmon run sees huge numbers of fish return from the sea to spawn in freshwater. Making their way upstream, they follow the imprinted scent of their birthplace. Along the way are numerous obstacles - including grizzly bears. As the forest giants prepare to hibernate, they eat tons of salmon. The nitrogen-rich leftovers feed smaller mammals but also, amazingly, trees. We examine the fragile balance of this unique relationship.

Absolutely wonderful video aside (i LOVE the “nutrient pumps” like this; whale pumps, guano etc), one minor (and somewhat snobby) correction (or at least caveat) : Trees, despite being a major carbon *reservoir*, are not a great carbon *sink*. Peat Bogs, Swamps, and Algae are the main long term carbon sinks (Hence your Coal, Oil/Natural Gas, and misc stuff like Shale/Bituminous Sands/Diatomaceous Earth etc) I hope this doesn’t come across as rude, and i get the reason why this could be a good talking point, but this and the Oxygen Production point sometimes mentioned are a bit incorrect so I thought that may be worth pointing out. All that aside this video was really neat! (i was unaware of this nutrient pump and it’s interesting!) (Semi-Random thing, i think “reverse coal mining” with Carbon Black (from methane pyrolysis etc), or slurries of biomass etc would be an interesting carbon sequestration method, although the more conventional enhanced weathering probably makes more sense.
