Your Brain On Pollution

If you and your pod are going somewhere and you can't hear them, not helpful.
P
45:04PetaHOST
So yeah, this study is the strongest evidence yet that a chronic exposure to cyanobacterial toxins such as BMAA and DAB can lead to neurodegenerative disease in wild mammals, and probably also us.
P
45:18PetaHOST
It demonstrates that dolphins' navigation errors and strandings might be from this cognitive decline.
P
45:24PetaHOST
And it's showing the bioindicators that toxal algal blooms are changing brain chemistry of marine mammals.
Three Floating Staple Crops
S
14:14Shane SimonsenHOST
So the direct edibility of Azolla for humans is contested.
S
14:20Shane SimonsenHOST
Um, it is established for producing protein-rich feed for animals, but the presence of, uh, potentially contaminating unnatural amino acids, uh, there's one particular called BMAA, uh, which is linked to neurodegeneration.
S
14:34Shane SimonsenHOST
Um, there's a host of other anti-nutritive compounds that are present that limit its direct use as human food.
S
14:41Shane SimonsenHOST
So, you know, you can feed Azolla to animals, and that's one simple pathway for protein production.
Special Episode: Clayton Page Aldern & The Weight of Nature
C
29:05Clayton Page AldernGUEST
True, and there are a lot of different flavors of cyanobacteria out there.
C
29:08Clayton Page AldernGUEST
What we're learning about a handful of them is that in addition to producing a neurotoxin, uh, which is called beta-methylamino-L-alanine, or BMAA, in addition to producing this neurotoxin that is indeed released into water, it appears that the neurotoxin itself is probably airborne.
C
29:28Clayton Page AldernGUEST
And so folks who live on the perimeter of these lakes, the perimeter of this brackish water, may also be exposed to aerosols containing BMAA.
C
29:38Clayton Page AldernGUEST
And this is dangerous because heck of a lot of lab studies have shown relationships between BMAA exposure, both oral and through the nose, right, nasal, have these relationships with excitotoxicity, cell death, neurodegeneration.
C
29:55Clayton Page AldernGUEST
BMAA exposure is, you know, one of the primary causal predictors of rates of amyotrophic lateral sclerosis, or ALS, Lou Gehrig's disease, motor neuron disease.
C
30:07Clayton Page AldernGUEST
It's been implicated in the development of things like Parkinsonism, Alzheimer's.
C
30:12Clayton Page AldernGUEST
And the real dangerous thing here, uh, when it comes to a changing climate is that, uh, these blooms are increasing in size and frequency as a function of climate change, right? What do they need to survive? They need sunlight.
