This issue's topic: Breathe
Keywords: oxygen diatoms
Added knowledge point: "Without oxygen for energy, all living things are no longer than the size of a pinhead."
Afterthought: It turns out that the energy provided by oxygen is an important substance to promote biological growth, not just to maintain life.
Oxygen and the food we eat work together to unleash the power of life
Growing knowledge point: "Where does oxygen come from in a desert of salt?
Every year, astronauts observe dust storms from North Africa floating above the Amazon Basin and they become the ideal fertilizer for the tropical rainforest. The elements of dust continue to penetrate the rainforest and cause plants to convert carbon dioxide into oxygen, but the oxygen will not leave. The Amazon rainforest feeds the animals of the rainforest.”
After watching: I have long heard that the Amazon rainforest is the lungs of the earth and has always thought that it directly supplies oxygen to us. Now I know that the animals that make oxygen in the rainforest consume it.
Added knowledge point: "Tropical rainforests don't supply us with oxygen directly but through a 'Tianhe' in the Amazon Basin
Look deeper through the tree trunks and you can see the moisture absorbed from the woodland when the moisture reaches the top of the branches and leaves, under the action of the sun and the breeze, the water vapor gathers into a river.”
After viewing: Nature is really beyond imagination! Tianhe is so beautiful. When I saw this, I was amazed except "Wow"! It's just "stupid"!
Added knowledge point: "This river of clouds and mist flows over South America until it is blocked by the Andes Mountains
These clouds condensed into rain that ran down the mountain and then flowed back to the Amazon Basin, where water washed rocks to form sediments that flowed into the sea
Those who enjoy these sediments are the diatoms in the sea
Diatoms, which are less than a quarter of their volume, use the silica in the rock to create new shells to thrive and are the secret weapon for the planet's oxygen supply. Every diatom provides oxygen."
After watching: I was really eye-opening. I didn't expect that the oxygen that provides us with our survival is so inconspicuous. It even takes a microscope to see the real marine creatures!
It is so important to us, it is indispensable! How I feel about this can be described in two words: "Oh my God! It's amazing!"
Diatom waters stretch for thousands of miles
Growing knowledge point: "Diatoms also produce great value after they die
Diatoms are found in every ocean, and they absorb nutrients in a variety of ways
When the glacier bursts, the nutrients that support the diatoms fall into the water together with the debris of the glacier, which is the best food for the diatoms. "
After watching: The diversity of diatoms' living methods brought me the insight that the different living methods of organisms, followed by different living environments, also created the diversity of natural creatures.
Added knowledge point: "Once the prosperity is over, the diatoms will soon fall to the seabed and form an eight-hundred-meter-thick blanket called sea snow, and they will never melt.
Hundreds of years later, the seabed will rise, the sea level will fall, the seabed will become a salty desert, the desert dust will promote the rain forest, and the dust will be the shell of the diatom.”
After viewing: once again sighed at the magic of the great creator of nature!
The "Internet of Things" in nature is intertwined in cycles!
Increased knowledge point: "Everything is on an arrow, nature is a great system "engineering", and everything operates in a natural system!
There is a wonderful connection between all things. Objects on one end of the earth are connected in some way to objects on the other end.
But not too much oxygen
Added knowledge point: "The atmosphere is thin and gravity pulls on every atmospheric particle and pulls it above the ground.
The higher the altitude, the thinner the atmosphere, the less oxygen there is until it disappears.”
Post-view: That's right! Years of doubts solved!
If there is a lack of oxygen, the function of human organs will decline rapidly
Added knowledge point: "But too much oxygen can also be dangerous. Oxygen will make the flames burn. Too much oxygen can even destroy us. Too little oxygen suffocates us.
Life is in balance The population is growing The oxygen content of the atmosphere remains stable at 20.95%
All things buffer each other in some way to keep the atmosphere in a steady state.”
After watching: the moon is full, the deficit is full and the water is full. The balanced ecological environment formed by nature for thousands of years is definitely the best state!
Therefore, we must not wastefully destroy the environment and break the balance of all things. The consequences are unimaginable, and even self-destruction!
All things on earth are related to each other
Increased knowledge point: "The earth truly achieves the unity of man and nature, which is a vivid sign that is unique in the universe.
The earth is a whole and our common home"
Post-viewing impression: Seeing this reminds me of Taoism, one life two two begets three, and three begets all things!
All things are nature, and there are Taos and Dharma, which are naturally endless and closely related!
More and more admiration for the philosophical thinking of the ancient Lao Zhuang Taoism, it is really a torch, the realm is really high! "Gao Lao Zhuang" ah!
I deeply realized that nature is a whole, and we are partners in a boat!
Therefore, I have a deeper understanding of the profound implication of "building a community with a shared future for mankind" proposed by President Xi Jinping! Great meaning!
