Myth busting – Part 11

Continued from Myth busting – Part 10. If you have not read Part 10 yet, I suggest you go start there, in order to keep everything in context. Thanks!

Carbon sequestration

 

To be clear on usage of certain terms:

Carbon (organic carbon) means the mineral carbon, an essential building block of all organic life on Earth – plants and animals, including humans.

Carbon dioxide means the gas breathed out by animals, and taken in by plants. Carbon dioxide is a naturally occurring gas in our atmosphere – but human activity burning fossil fuels has increased the amount.

Over millions of years, plants ‘breathe in’ carbon dioxide and use it as a building block for cellular life. As those plants grow up into big strong trees, so the dense wood holds lots of carbon. When the tree dies, the logs fall to the ground and are buried in new growing organic matter. That carbon is taken down into the ground and stored for many years, slowly releasing its mineral content into the soil to nourish other plants and animals. This is a crude explanation, but you get the idea.

Carbon sequestration means ‘taking carbon dioxide out of the atmosphere and storing it as carbon bound up in life forms (such as wood, plants, soil, insects, etc.)

A carbon sink is a place or thing that acts to sequester carbon, such as a tree.

Mother Nature provides places to sequester carbon naturally. The oceans, the topsoil, the forests and peat bogs (peat wetlands or peatlands) are all massive efficient carbon sinks, the world’s top four. The problem is, those carbon sinks are not working optimally.

Where have all the fishies gone?

Approximately 70% of the planet is covered by oceans and seas. Currently, around one third of all the carbon dioxide from the atmosphere is sequestered by our oceans. They could be taking a lot more.

However, there is a problem with our oceans. We have over-fished them for the last century or more, and the result is that early in the 21st century we find that 85% of fisheries worldwide are over-fished and seriously depleted. We have massively reduced fish stocks in our oceans, and the use of trawlers and supertrawlers has decimated marine life, hurting Mother Nature’s ability to restore what we have taken. In some species, over 90% of living stock has been wiped out over a few decades, reducing numbers below a certain ‘critical mass’ to such a point that populations can’t recover. This means the oceans have a reduced ability to sequester carbon from the atmosphere, due to lower levels of biological activity in ocean waters.

You see, it’s supposed to be the life in the water that sucks up the carbon…not the water itself. However, with more carbon dioxide in the air, our oceans are also suffering from something called ‘ocean acidification’ which means the water itself is absorbing carbon dioxide from the atmosphere, because there is more there to absorb, and it’s changing the pH of ocean waters, reducing the oxygen-richness of ocean waters. This makes it harder for marine life to proliferate. It’s a double whammy, and a vicious negative cycle.

We need marine life to proliferate in order to sequester carbon. Ocean acidification, over-fishing and pollution have left the oceans with reduces amounts of algae, phytoplankton, seaweed and fish. The result is that our best carbon sink isn’t working at all well, and the largest part of the planet’s surface, that should supply a huge proportion of our food, is drastically depleted. The answer must be to stop over-fishing, stop polluting our oceans with plastics, chemical waste and more, stop polluting the atmosphere with burned fossil fuels and let the oceans work naturally, the way they are supposed to.

Without trying to sound too melodramatic about it, it’s a bit like the zombie apocalypse, but underwater. Reduced life, pollution, loss of marine biodiversity, massive scars of land destroyed by trawlers, ‘kill squads’ out slaughtering marine life en masse. What’s happening in our oceans isn’t pretty.

Myth busting – Part 5

This post is Part 5 of a continuing series of posts tackling persistent myths in the world of healthy eating, with a particular focus on the consumption of animal foods as a source of ill health and environmental destruction.

You may like to read the whole series starting from Myth busting – Part 1

Myth: But big strong animals like gorillas don’t eat meat. A gorilla is a vegan and he’s made of muscle! So who needs all that protein now then?!?!

You may have seen this image circulating on social media sites, lots of folks who don’t really know much about health and nutrition like to share this image as some kind of ‘proof’ that it is healthiest to be a vegan, and no one needs to eat animal foods at all.

I don’t want to sound rude, and this next line isn’t meant to be an attack on any vegans or an insult to anyone specifically, but in all honesty, sharing this Internet meme as some kind of ‘proof’ that people shouldn’t eat meat is pretty much the highest display of ignorance out there in the whole ‘meat vs. vegetarian’ discussion.

Not ignorant because the people sharing it don’t know much about the digestive system of a gorilla; that’s fair enough, most folks probably don’t; but ignorant because the people sharing this are stupid enough to think the digestive function of one animal somehow acts as some guide of evidence-based scientific guide to the digestive system of another. That is just plain dumb.

Why would the digestive system and food habits of a gorilla have anything to do with a human?

Oh because gorillas have muscles, therefore this is ‘proof’ of how to build muscles?

Well elephants have muscles too; maybe I should eat an elephant’s diet? Read more

Symbiotic relationships and the wonder of Nature

In so many ways, I find wonder in all that Mother Nature does. Things that often appear simple, are often in fact wondrously complex.

As a home-based worker in a small office with big windows looking out the back, I have quietly studied this garden of mine every day for the last 12 years, and for 12 years I have watched the squirrels take the hazelnuts from our hazel tree and bury them all over the garden. I regularly remove them from the lawn, the strawberry patch and the flower beds, and I feel pretty sure that if I hadn’t been doing that for 12 years, by now Read more

The 12 Core Principles of MotherNaturesDiet are very carefully balanced to help you focus on the MOST important issues in improving overall health.

The 12 Core Principles of MotherNaturesDiet are clustered in 3 groups:

Group 1: Things to quit 12 Core Principles - 3

Group 2: Things to consume

Group 3: Exercise and lifestyle factors

Each group contains 4 Rules. All these rules are brief and purposefully simplified – MND is all about keeping it simple, to help ordinary busy people cut through the ‘diet industry’ and ‘health industry’ marketing bullshit and get to what really works.

You’ll see that there are TWICE AS MANY Rules about ‘what not to eat’ as there are about ‘what TO eat’. This is structured this way on purpose, because I believe it is TWICE as important to get all the crap OUT of your life than to spend all your time worrying about the nuances and minutiae of what you should be eating. Diet perfectionism be damned, just eat real whole foods, eliminate chemicals from your body and avoid ALL processed foods, and you’ll have ‘the diet thing’ 90% licked. Read more

Secrets of longevity

“I mind my own business and I don’t eat junk food.”

Following her husband’s death at the age of 68, in 1963, Cooper lived alone on their farm until 2001, when she moved into a nursing home at the age of 105. Their FARM, please note.

 

Longevity secrets

Increasingly, I find myself drawn to research around longevity. Many studies suggest that in fact, a lot of the ‘trends’ or factors we associate with good health are not necessarily shown to be the factors that prove instrumental in promoting a longer life.
