remember, but but it is garden. they re like ten times better at it than the amazon rain forest for example, those ecosystems are mango forest seagrass meadows, and salt marshes. we were taking field recordings throughout the whole film and then i took all those field recordings and made a song out of it, essentially. and you get to hear that song at the end. the fell, i want to make a new anthem for nature by recording the sounds of coastal habitats that we don t value enough you play these and festivals. yeah. yeah. how do you connect your music audience with what you care about as a biologist, as an ecologist incorporating those sounds automatically gives me something to talk wow, because people really care and they re interested. there s your j to g, the dj persona. but then there s j to the biologist and that s a paradox at times given the footprint, the energy use at festivals and all of that, but it definitely is a paradox like i m a turing dj. i have to fly to my gigs and
carbon out of the atmosphere and the ocean and then burying it in the soil below them as we saw in that clip there that black mud, muddy. the. mud that we think of when we think of coastal swamps, is this amazing long term storage of carbon and it s kept there for millennia we beginning to appreciate now, we re beginning to see countries really understand how important their coastal wetlands systems, these salt marshes, seagrasses, mangroves, as part of their full climate solution dr. pigeons, there s no shortage of incredibly alarming studies, reports documentaries on this earth, de, on monday, what s your message? my message is that the solution to climate change needs all of us. it needs everybody from government to corporations to communities, to every single individual.
nicholas. oh, get that earpiece together. we need to hear each other. okay. yeah. okay. so first up, i she just gave us a summation of what blue carbon is, but break it down for us. what is blue carbon? we re going well, technically blue carbon is three acre systems mangroves, salt marshes, and seagrasses. so it s that liminal space in-between the land and the ocean. and it just happens to be fantastic at storing carbon and it also has these other added benefits, which is kind of what we discovered for it as we went along in the film, which is like coastal protection and fisheries so it s one of these win-win situations for the environment and is there a feeling that they are flourishing or how much more are they being threatened? i mean, it s getting better. people are recognizing now that these are really important ecosystems, both from a bio, but biodiversity standpoint and from the climate standpoint. but so far we, we ve kind of hated swamps like traditionally
The recovery of top predators is thought to have cascading effects on vegetated ecosystems and their geomorphology1,2, but the evidence for this remains correlational and intensely debated3,4. Here we combine observational and experimental data to reveal that recolonization of sea otters in a US estuary generates a trophic cascade that facilitates coastal wetland plant biomass and suppresses the erosion of marsh edges—a process that otherwise leads to the severe loss of habitats and ecosystem services5,6. Monitoring of the Elkhorn Slough estuary over several decades suggested top-down control in the system, because the erosion of salt marsh edges has generally slowed with increasing sea otter abundance, despite the consistently increasing physical stress in the system (that is, nutrient loading, sea-level rise and tidal scour7–9). Predator-exclusion experiments in five marsh creeks revealed that sea otters suppress the abundance of burrowing crabs, a top-d
