Importance of Air for Survival of Life

Have you felt a constant pressure around you but you cannot visualize it? That is the air that surrounds us. The effects of air are felt within the natural surroundings, as the trees sway or the cold wind blows. The high-velocity air that flows is usually referred to as breeze. We cannot see air but it can be felt around us. Without air, life wouldn’t be in existence. Air was assumed to be made up of a single substance earlier but now it is understood that it is a mixture of gases. Essentially, nitrogen and oxygen are the basic components that are allowing us to sustain on the planet.

Importance of Air to Human Life

To respire we need oxygen. Even the animals in aquatic habitats need oxygen to sustain themselves. Air is the fundamental element that keeps us alive. In fact, the water bubbles are a result of trapped air. Isn’t it interesting? Water to dry soil forms bubbles which is nothing but trapped air. The water is displaced by air molecules forming bubbles. Organisms that live in the soil respire through the oxygen present inside the air. Water fills the empty spaces and we hence see the organisms like earthworms coming up during the monsoons.

Importance of Air for the Survival of Life

We utilize oxygen almost all the time yet it remains unexhausted. This is because the trees restore this oxygen to the environment in the course of the process of photosynthesis. Plants also use oxygen but their utilisation is very minimal as contrasted to their oxygen production. Consequently, the remaining result is that they complement oxygen in the atmosphere. All the animals and plants are codependent on each other for their subsistence, plants make oxygen, and creatures yield carbon dioxide as a by process, hence they survive with one other creating a bio-network of their specific self. Conversely, due to artificial involvements and activities, such as deforestation and industrial units smog, smoke, and other substances and chemical components are discharged into the air causing air pollution. 

Air gives the impression of being light, but there is a lot of it roughly pushing down on the earth’s surface. This is termed air pressure. You undergo high air pressure at sea level for the reason that the whole atmosphere is impelling down on you. The air pressure is depleted on top of a highlands because there is a lesser amount of atmosphere approaching down on you. That difference in air pressure can produce your ears to pop when you’re taking off in an airplane or driving up a hill.

Air presents a lot of diverse expenditures that make it an imperative and indispensable requirement in our daily life, deprived of air Earth would be just like the other lifeless planets in our planetary classification, without any plants, animals, or living beings. Without air; life itself would terminate to survive. 

Without air, plants would be incapable to conserve up the practice of photosynthesis and without them, animals who are entirely dependent on plants for their endurance would succumb too. Furthermore, there would be no resonance if air did not subsist and we would be encircled in a vacuity bubble. Separately from this, the cross-fertilisation of harvests would not happen and thus, there would be no foodstuffs or food for us. Thus, the air is the principal basic component that is compulsory for the existence of any living species.

No one can see the air around but can definitely experience its presence every second. The air effect can be observed everywhere around us, from the movement of our hair to the swaying of plants and trees. Though the fact is that no one can see the air, one thing is clear that no one can live a life without air. In ancient times, it was said that air is one single gas which is oxygen but now it is known that air is a mixture of different gases. The mixture of Nitrogen and Oxygen in an appropriate percentage helps people to live in such sustainable conditions on this planet.

Importance of Air

Air helps in oxidation processes which supply the body with the necessary energy. Air has various different applications in various fields of industry. Some common uses of air are: 

Air is an important supplier of energy, it means that every living plant and animal depends on oxygen to generate the energy necessary for them. Body cells take oxygen flowing from the blood and produce energy after consuming food in the form of ATP. ATP is the biochemical generation that is essential to maintain life on the Earth. Therefore, ATP is one of the uses of air. 

Air is a conducting medium for sound, it means that people hear the sound of speech or noise, etc. when there is air around them. These noises happen because the wind is a good sound conductor. Without a solid medium, people are not able to hear anything and they won't be able to produce the sounds.

Air is also an important part of the water cycle, it is described as the water cycle is a phenomenon of water from the soil, the oceans, and seas evaporating the water due to the heat of the sun and forming clouds. These clouds will then move towards the land surface, and then these clouds are cooled by wind and rain. And the rainwater again mixes with the sea and ocean.

Air is responsible for the pollination of crops, it means that plants produce male gametes in pollen grains. These grains move from one male flower to another female flower and combine with female gametes, and this process is called pollination. Pollination occurs in flowers growing on the same plant or between remote plants with the help of wind power.

Pollination helps In keeping the balance of the temperature on the Earth's surface when it's summer. When the sun strikes a large amount of heat on the Earth's surface, the surface temperature of the ground will rise rapidly, but it grows slowly on the surface of the ocean or sea because a solid substance is heated faster than liquid water. Therefore, the warmed air at the Earth's surface rises up, and the cold air from the sea surface transfers to the surface of the ground that minimizes the temperature rise. 

Air helps in drying the moisture balance, it means the ground that becomes wet from the rain will dry due to air. Though the wet surface is very moisty. Therefore, the moist layers are replaced by less humid or dry layers of air. The new dry layer formed on the surface will absorb moisture from the wet surface, and the cycle continues until the surface is dry. 

Air also helps to swim in the water. It means when lungs are filled up, one should swim higher in the water. When the air is passed towards the restricted area then it is known as compressed air. Air can easily be found in the tires of cars, bicycles, and planes used in flight mode. 

Air reduces pollution, which means that environmental pollution is a serious problem since the current way of living leads to different kinds of pollution. The ozone surrounding it helps to minimize the level of environmental pollution. 

Wind energy can be used to generate large electricity with the help of wind turbines installation. These turbines rotate under the influence of the wind and generate electrical energy. The generated electrical energy is not polluting and can be generated anywhere on the Earth for any domestic use. 

Air is very useful as a natural resource, similar to water, the air has lots of applications too. The most important point of air is that it supports the life of all living beings on Earth, providing them with enough oxygen. Though oxygen is not only essential for living things, instead candles, iron, fire, collected fruits, and vegetables tend to change under the influence of oxygen. For example, candles and fire need oxygen to continue burning. Iron will rust only when exposed to water and oxygen. Fruits and vegetables start changing colour and eventually become moldy due to the moisture and oxygen in the atmosphere. 

This is all about the importance of air for the survival of life on earth. Air offers the most essential ingredient to conduct the life processes and can also play a corrosive role. Understand the importance of air and imbibe the concepts well.
