Educating Red-Hair
The atmosphere helps maintain a relatively stable temperature on Earth; without it, daytime temperatures would be very high, while nighttime temperatures would be very low. The ozone layer absorbs ultraviolet radiation from the sun, protecting life on Earth from harm. The atmosphere prevents excessive high-energy particles from space from entering Earth and prevents meteorites from impacting, as meteorites can be slowed down and burned up when they rub against the atmosphere. Wind, clouds, rain, and snow all depend on the atmosphere for formation. Sound travels using air. Parachutes, deceleration parachutes, and airplanes also utilize the forces of air.
Without air, our world would be a barren desert, devoid of any life. Green plants use carbon dioxide from the air, along with sunlight and water, to synthesize nutrients. In this process, oxygen is released. Humans and other animals breathe air to obtain oxygen, and animals also need oxygen to obtain energy from the food they ingest.
Industrial development has released harmful substances into the air, polluting it and increasing the amount of harmful components. When these harmful substances reach a certain concentration, they can seriously damage human health and crop growth, destroy certain substances, reduce visibility, and affect traffic safety, among other things. Therefore, it is imperative to take strong measures to prevent air pollution.
Harmful substances emitted into the air can be categorized as follows: particulate matter (such as carbon particles), metallic dust (such as iron and aluminum), wet mist (such as oil mist and acid mist), and harmful gases (such as carbon monoxide, hydrogen sulfide, and nitrogen oxides). Globally, sulfur dioxide and carbon monoxide are the most emitted and harmful gases. Sulfur dioxide is produced during the combustion of coal and petroleum.
Air pollution index (API) levels are as follows: 0-50 is Level 1; 51-100 is Level 2; 101-200 is Level 3; 201-300 is Level 4; and above 300 is Level 5. Level 3 is considered light pollution, Level 4 is moderate pollution, and Level 5 is heavy pollution.
And I can control the composition of the air.
After all, increasing the amount of a harmful substance means that every time you breathe, it's equivalent to inhaling poison gas.
Alternatively, you could simply make a space a vacuum, which would also result in nothing being there.
Humans would then be unable to breathe.
Of course, or like I just did, we could directly turn the air in this area into pure carbon dioxide, and then into pure oxygen.
Excessive carbon dioxide in the air can cause a range of health problems in humans, including lethargy, slowed breathing, mood and behavioral abnormalities, respiratory acidosis, metabolic alkalosis, and pulmonary encephalopathy.
This is just exceeding the limit; pure carbon dioxide, even just one breath, can render an ordinary person immobile.
Similarly, excessive levels of pollutants in the air can lead to a variety of health problems, including oxygen toxicity, atelectasis, respiratory depression, organ damage, disruption of immune balance, oxidative damage, and nervous system dysfunction.
Oxygen toxicity is one of the most direct and serious effects. When the oxygen concentration is too high, the oxygen free radicals produced by the human body exceed the body's defense capabilities, leading to damage to cell structure and function. Symptoms may include convulsions, rapid breathing, altered consciousness, narrowed visual field, nausea, and dizziness. In severe cases, it can even lead to acute respiratory distress syndrome.
Atelectasis occurs when excessive oxygen concentration leads to the replacement of a large amount of nitrogen in the alveoli. When the bronchi are blocked, it can easily cause inhalational atelectasis, resulting in symptoms such as increased heart rate, elevated blood pressure, and difficulty breathing.
Respiratory depression occurs because excessively high oxygen concentrations may relieve the stimulating effect of hypoxia on respiration, exacerbating the inhibition of the respiratory center, and in severe cases, may lead to respiratory arrest.
Organ damage and disruption of immune balance are also potential risks of long-term exposure to oxygen-rich environments. Excessive oxygen produces free radicals, leading to oxidative stress, which damages cells and tissues, while also affecting the normal function of the immune system, making people more susceptible to diseases.
Oxidative damage and nervous system dysfunction are also possible consequences of high concentrations of oxygen. Oxygen can promote the oxidation of certain substances, producing harmful substances that pose a potential threat to health. At the same time, prolonged exposure to oxygen-rich environments may increase the excitability of nerve cells, leading to nervous system dysfunction.
Therefore, although oxygen is essential for life, excessively high concentrations of oxygen still pose potential health risks to humans. It is necessary to reasonably control oxygen concentration and avoid prolonged exposure to high-oxygen environments.
Listening to Moke's detailed explanation, the Red-Hair carefully recalled the events of the previous battle. His lips twitched slightly...
This ability...
What's the point of fighting?!
A ceasefire was indeed the wisest decision.
With this ability, one is probably already invincible!
If this kind of move were used over the Sky Holy Land, I estimate that 99% of the Celestial Dragons would be killed.
