What is environment ?
Environment is defined as “the surroundings in which an organization operates including air, water, land and natural resources, flora, fauna, humans and their inter relations” – ISO Definition.
Webster's Dictionary defines the environment as, "The circumstances, objects, conditions by which one is surrounded, the complex of physical, chemical and biotic factors, that act upon an organism, or an ecological community and determine its form and survival, the aggregate of social, cultural factors that influence the life of an individual or community."
As per American Literature, following are the components-
The hydrosphere represents one component of earth's system, operating in conjunction with the solid crust (lithosphere) and the air that envelopes the planet (atmosphere).
According to the research, hydrosphere basically a combined mass of water that is found on earth, that makes up around 71% of the earth surface which is covered with water.
Its major components are Nitrogen (78%), Oxygen ( 20.96% ), Argon ( 0.93% ), Carbon-dioxide ( 0.032% ), and other inert gases.
The atmosphere filters the incoming ultra-violet (UV) radiation and protects the earth’s surface.
Troposphere, Stratosphere, Mesosphere, Thermosphere are the four types of atmosphere.
The earth's crust consists of rocks and soils made up of different chemical elements and minerals.
The lithosphere occupies 30% of the total Earth’s surface.
The lithosphere is about 100 km thick, although its thickness is age dependent (older lithosphere is thicker).
The anthroposphere (sometimes also referred as technosphere) is that part of the environment that is made or modified by humans for use in human activities and human habitats. It is one of the Earth's spheres.
As human technology becomes more evolved, so do the impacts of human activities on the environment.
Examples: deforestation for housing, land setup, etc.
Environment is highly delicate (fragile) and so we have to live in harmony with it.
Environment holds a key role in the economic growth and the survival of living things.
