The Environment

Environment is defined as the total planetary inheritance and the totality of all resources. Environment (derived from the word ‘Environ’ meaning to encircle or surround) can be defined as the physical and biological world where we live.

Environment is nothing but the sum total of all surroundings of a living organism, including natural forces and other living things, which provide conditions for development and growth as well as danger and damage.

It can be subdivided according to its attributes.

MARINE ENVIRONMENT refers to ocean, a body of saline water that comprises much of our planet’s hydrosphere. It is known to all of us that 75% of the earth consists of water bodies. As the world ocean is the principal component of earth’s hydrosphere, it is integral to all known life, forms part of the carbon cycle, and influences climate and weather patterns. The ocean world is the habitat of 23000 known species, but because much of it is unexplored, the number of species that exist is much larger; probably over two million.


Atmosphere is nothing but a layer of gases surrounding a planet or other material body.

The atmosphere of earth comprises N (78%) (21%) argon (0.9%) CO2 and other gases in trace amounts.

  • Oxygen is used by most of organisms for respiration.
  • Nitrogen is fixed by bacteria repair.
  • Ammonia is used in construction of nucleotides and amino acids.
  • CO2 is used by plants, algae, etc.


The concept of terrestrial environment relates to the interaction between natural components of the geosphere and biosphere as well as their interaction with social and economic factors with special emphasis on the territory in which they are deeply rooted. Terrestrial environment includes forests, grasslands and deserts, a community of organisms and their environment in the oceans and on the land masses of continents and islands.

‘There is no need to protect environment but there is a need to create a world where the environment does not need protection.’

‘The greatest threat to our planet is the belief that someone else will save it.’

I would end by saying ‘A clean environment is a human right like any other. It is therefore part of our responsibility towards others to ensure that the world we pass on is as healthy if not healthier, than we found it.’

Shahnaz Chandniwala is M.Sc., B.Ed. in Organic Chemistry.

I have devoted more than one and half decades in the field of Education. I have been working with Rumi English High School since 2000. I have 12 years experience of teaching secondary and higher secondary classes. I was appointed to the post of Principal in 2012. In my opinion students, teachers and parents together play the foundation role as stakeholders for the achievement of ultimate goal of creating global citizens.

I sincerely and strongly believe that real education lies way beyond books. To implement the same I encourage my teachers to bring to the fore the inner capabilities of the students rather than inserting anything.

My goal is to encourage my students to be ambitious and to reach for their dreams, to step outside their comfort zone and try something new.
