Environment is the sum total of what is around
something or someone. It includes living things and
natural forces. The environment of living things
provides conditions for development and growth, as
well as of danger and damage. Living things do not
simply exist in their environment. They constantly
interact with it. Organisms change in response to
conditions in their environment. The environment
consists of the interactions among plants, animals,
soil, water, temperature, light, and other living and
non-living things.

• It is also known as a-biotic environment and natural
environment.
• The meaning of ‘a-biotic’ or ‘physical’ is non living like land
water air conditions atmosphere which constitutes of soil. So
we can say that physical or a-biotic environment is the
environment which includes non living or physical things
which are constitutes of soil and affect the living things.
• The physical or a-biotic environment also includes
the climatic factors such as sunbeams, rainwater,
precipitation, moisture, pressure and wind speed.
The Physical environment

4.
• It is also known as biological environment and organic
environment.
• In the opposite side of the physical environment, the biotic or
biological environment is responsible for the living beings.
• You have already understood that the meaning of ‘biological’ is
living things. So, the biological environment is the environment
which involves the living part of the earth.

Human impact on coral reefs is significant. Coral reefs are dying
around the world. In particular, coral mining, pollution(organic and
non-organic), overfishing, blast fishing and the digging
of canals and access into islands and bays are serious threats to these
ecosystems. Coral reefs also face high dangers from pollution, diseases,
destructive fishing practices and warming oceans.
Global warming is the result of increasing atmospheric carbon
dioxide concentrations which is caused primarily by the combustion of
fossil energy sources such as petroleum, coal, and natural gas, and to
an unknown extent by destruction of forests, increased methane (post-
industria1: 150%), volcanic activity and cement production. Such
massive alteration of the global carbon cycle has only been possible
because of the availability and deployment of advanced technologies,
ranging in application from fossil fuel exploration, extraction,
distribution, refining, and combustion in power plants and automobile
engines.

• Painting your house? Use a latex paint. Oil-based paints release hydrocarbon fumes.
• Get a tune-up. Properly maintained vehicles get better gas mileage and emit fewer
pollutants.
• Use less fertilizer on your lawn. When it rains, excess fertilizer runs off into storm sewers
and pollutes streams.
• Never pour anything – especially waste oil or leftover lawn chemicals – into a storm drain.
It will end up in the nearest stream.
• Recycle. If your community does not offer a recycling program, ask local officials to start
one.
• Don’t put hazardous materials in the trash. Save paints, pesticides, lawn chemicals, car
batteries, waste oil and similar materials for your local household hazardous waste
collection day.
• Paper or plastic? Better yet, take a canvas bag to the grocery and re-use it each time you
shop.
