00:05Es un problema muy mal
00:08La mayoría de los problemas
00:09son que piensan lo que lo que se ve en la Tierra
00:12es normal y natural
00:13cuando es algo más.
00:16En los últimos años
00:18hemos realmente notado
00:20una gran decline en la Tierra.
00:22Están muy bajosos, no me dano
00:23de acuerdo, han reducido al menos
00:2670%.
00:27Salmones en crisis.
00:30I think it would be lazy
00:31to say that all the problems
00:33for Atlantic salmon are at sea.
00:35It's becoming more apparent
00:37that survival of salmon at sea
00:39is also linked to the conditions
00:42in fresh water.
00:45The surrounding
00:46land use has a huge effect
00:47on what happens
00:49in the river.
00:52We don't look at the
00:53upland river catchments and think
00:55they should be trees, but they actually
00:57should be trees.
01:00What we've done essentially
01:01is turned the hills from a
01:02thatched roof into a slate roof.
01:06If we don't get trees
01:07in them in the next few decades
01:08we're going to lose salmon from over
01:10300 kilometres of river potentially.
01:14What salmon do is
01:15they take marine nutrients
01:17and bring them back into the river systems.
01:20That
01:21nutrient that they've taken
01:22from the sea get taken up
01:24by all the animals, the vegetation
01:26and even the trees.
01:29No one animal exists in isolation.
01:33It's a deeply interconnected web.
01:37I don't think anyone wants to be known
01:40for abusing the land anymore
01:41and we've all been guilty of it.
01:45Scotland without salmon
01:46is definitely a possibility
01:48and it would be a tragedy.
