Mindanao Freediving

Thank you MariaZosa Freediving for teaching the Junior program. We can offer now the freediving certification JW1/JW2 & JW3 for the Junior 11 to 15yo. Let's jump in this new program and try to use it in the best with The Trinity Project

Physical preparation.
I have been running since 2020
In April I integrated the running sessions for the deep comp in November.
1) April 25 - 5k in 45', speed 6.67kmh pace 9'/km
2) June 23 - 13,89k in 1h50 - speed 7,58kmh 7'55/km
30 JULY 1st 5,47k / 36'28 = speed 9kmh pace 6'40/km.
I'm close to the 6'/km
This week return to deep water training + 3x pool session + 1x Hiit session + Stat in swimming pool

To be a freediver is easy, when you immerse your face in the water you trigger your mammalian dive reflex. You push your body to react in bradycardia, vasoconstriction, spleen effect, blood shift & vasodilation. That increase your relaxation into the water for diving deeper, longer and safer.

Sixth Mass Extinction of Life on Earth Caused by Humans.

How can we protect biodiversity?
Answer: We can support regional or local projects aiming to protect biodiversity.

A mass extinction is a short period of geological time in which a high percentage of biodiversity, or distinct species—bacteria, fungi, plants, mammals, birds, reptiles, amphibians, fish, invertebrates—dies out. In this definition, it’s important to note that, in geological time, a ‘short’ period can span thousands or even millions of years. The planet has experienced five previous mass extinction events, the last one occurring 65.5 million years ago which wiped out the dinosaurs from existence. Experts now believe we’re in the midst of a sixth mass extinction.

What’s causing the sixth mass extinction?
Unlike previous extinction events caused by natural phenomena, the sixth mass extinction is driven by human activity, primarily (though not limited to) the unsustainable use of land, water and energy use, and climate change. Currently, 40% of all land has been converted for food production. Agriculture is also responsible for 90% of global deforestation and accounts for 70% of the planet’s freshwater use, devastating the species that inhabit those places by significantly altering their habitats. It’s evident that where and how food is produced is one of the biggest human-caused threats to species extinction and our ecosystems. To make matters worse, unsustainable food production and consumption are significant contributors to greenhouse gas emissions that are causing atmospheric temperatures to rise, wreaking havoc across the globe. The climate crisis is causing everything from severe droughts to more frequent and intense storms. It also exacerbates the challenges associated with food production that stress species, while creating conditions that make their habitats inhospitable. Increased droughts and floods have made it more difficult to maintain crops and produce sufficient food in some regions. The intertwined relationships among the food system, climate change, and biodiversity loss are placing immense pressure on our planet.

Why should we care about mass extinction?
Species do not exist in isolation; they are interconnected. A single species interacts with many other species in specific ways that produce benefits to people, like clean air, clean water, and healthy soils for efficient food production. When one species goes extinct in an ecosystem or its population numbers decline so significantly that it cannot sustain its important function, other species are affected, impacting the way the ecosystem functions and the benefits it provides. And the potential for species extinction rises. Monitoring these trends is vital because they are a measure of overall ecosystem health. Serious declines in populations of species are an indicator that the ecosystem is breaking down, warning of a larger systems failure.

Currently, the species extinction rate is estimated between 1,000 and 10,000 times higher than natural extinction rates—the rate of species extinctions that would occur if we humans were not around. While extinctions are a normal and expected part of the evolutionary process, the current rates of species population decline and species extinction are high enough to threaten important ecological functions that support human life on Earth, such as a stable climate, predictable regional precipitation patterns, and productive farmland and fisheries.

If we do not course correct, we will continue to lose life-sustaining biodiversity at an alarming rate. These losses will, at best, take decades to reverse, resulting in a planet less able to support current and future generations.

The causes of biodiversity loss
Nature has its ways of controlling the population of living organisms. Most biodiversity is lost with seasonal changes and natural calamities. What concerns us are the human-driven causes of biodiversity loss. Here’s the list of reasons scientists have predicted the 6th mass extinction.

Population increase- The current population on Earth is 7.97 billion. Nature is paying the price to meet the basic needs of this population. We cut forests to make more land for residents and agriculture. It ruined the forest ecosystem and made species either migrate or adapt to a polluted land for survival.
Exploiting nature- Deforestation is one of the examples of humans exploiting natural resources. Uncontrolled fishing, hunting of wild animals, urbanization, oil extraction, etc., are the other ways we destroy nature. This is the major cause of biodiversity loss.
Climate change- The result of the above actions is climate change. Global warming or climate change has affected our planet more than anything. Rapid changes in the environment disturb the flow of life in species. One example would be the melting of ice glaciers. It raised the sea water level and endangered the living organisms in it.
Pollution- The result of the increased population is pollution. The basic elements of life, air, water, soil, and food, are all polluted. The air is polluted with hazardous gases and is almost unbreathable. The chemicals are mixed with water resources. Soil is losing productivity, and even fresh fruits and vegetables have high chemical residues. All of these are causing health issues for humans.

Key takeaways
Loss of biodiversity has two causes, natural and human-driven. The human-driven causes have made a significant impact on biodiversity.
Overpopulation and deforestation are the root causes of the imbalance in ecosystems.
Our collective efforts to protect biodiversity fail because of less attention and participation.

Freediving adaptations
Fisherman work long days with the "greatest daily apnea diving time reported in humans" of greater than 5 hours per day submerged.
More than a thousand years of subsistence freediving associated with their life on the sea appear to have endowed with several genetic adaptations to facilitate their lifestyle. A 2018 study showed that Bajau spleens are about 50 percent larger than those of a neighboring land-based group, the Saluan, letting them store more haemoglobin-rich blood, which is expelled into the bloodstream when the spleen contracts at depth, allowing breath-holding dives of longer duration. This difference is apparently related to a variant of the PDE10A gene. Other genes that appear to have been under selection in the Bajau include BDKRB2, which is related to peripheral vasoconstriction, involved in the diving response; FAM178B, a regulator of carbonic anhydrase, which is related to maintaining blood pH when carbon dioxide accumulates; and another one involved in the response to hypoxia. These adaptations were found to likely result from natural selection, leading to a uniquely increased frequency of alleles that are distributed among eastern Asian populations.

I dove with Angelo during 4 hours. An extraordinary ease in the water for Angelo with his plywood fins, diving goggles, shorts and T-shirt, long repeated dives between 10 and 15m without great difficulty and the gap between the freediver that I am with my carbon fins, mask, snorkel, weight belt makes me realize that I am still at the beginning of my freediving journey.

Bottlenose dolphins squeak, squawk and use body language—leaping as high as 20 feet in the air, snapping their jaws, slapping their tails on the surface of the water, blowing bubbles and even butting heads. Each dolphin has a special whistle that it creates soon after it is born. This whistle is used for identification, just like a human’s name. Dolphins also produce high frequency clicks, which act as a sonar system called echolocation (ek-oh-low-KAY-shun). When the clicking sounds hit an object in the water, like a fish or rock, they bounce off and come back to the dolphin as echoes. Echolocation tells the dolphins the shape, size, speed, distance, and location of the object.

Bottlenose dolphins have a sharp sense of hearing. Scientists believe that the sounds travel through the dolphin's lower jaw to its inner ear and then are transmitted to the brain for analysis.

Dolphins grow to be anywhere from 6 to 12 feet long. They shed their outermost layer of skin every two hours.
Very social and playful mammals, bottlenose dolphins form friendships that last decades hunting, mating and protecting each other. They like to surf in the waves and wakes of boats and swim through self-made bubble rings. They can swim up to 22 miles an hour.

These sea mammals feed on fish, squid, and shrimp. A group of dolphins will cooperate to make a mud ring to trap fish. Then, some of the dolphins in the group will wait outside the ring for the fish that try to escape, gulping them up as a snack.

Bottlenose dolphins are found in warm water all over the world. They live both in shallow water close to shore and far out in deep dark water. Dolphins face a lot of problems with getting trapped in the garbage humans leave on the beach.
