00:07all of them suddenly disappeared well biologist corey evans writes for the conversation it wouldn't
00:13be good and the cascading domino effect of their vanishing would be catastrophic first depending
00:18on how the fish left this world it could be disastrous for our own ecosystem for instance
00:23if all the fish suddenly died off that would be a massive carbon dump into our planet's oceans as
00:28fish are the second largest biological carbon group on the planet meaning if that carbon was
00:33released into the atmosphere it would be an insane amount to be let loose all at once but if they
00:37simply vanished they would still leave an incredible hole in the food chain even creatures that don't
00:42live in the sea feed on fish with further reaching impacts even on plant life evans writes that salmon
00:47that travel upstream to spawn and die provide some 70 percent of the nitrogen riverbank plants rely on
00:53this fish reliance also extends to species in the oceans as well with fish that live in and rely on
00:58coral for sustenance providing their own utility those fish eat algae to prevent the coral from being
