Hello! I’m Isay. Today we are going to
explore…
How does an environment affect an
organism?
The environment consists of two parts:
*Living things form the biotic
environment.
**Non-living things form the abiotic
environment.
https://www.bitmoji.com
4

They both can affect the growth of an organism.
Living things continue to exist as they use and interact with the environment.
One of the biggest threats considered that the world is facing today is pollution in the
environment. Overpopulation of humans and advancement in different areas have used up
natural resources. That eventually causes air pollution, water pollution, soil erosion, and
deforestation. Pollutions greatly affect the environment and all living organisms.
There are different types of pollution:
1. Air Pollution
3. Land and Soil
Pollution
2. Water
Pollution
4. Noise and
Light Pollution
Humans have created undesirable effects
on the environment. Human's abusive
activity brings harm, leading to the
destruction of the environment by
decreasing water, air, and soil resources.
The ruining of habitat even in the
destruction of ecosystems, the death of
wildlife, and pollution.
1. Air Pollution
The harmful particles in the air, either spec or
invisible, cause health hazards to all living
organisms, such as people, animals, or
plants. Air pollution comes in various forms
and may include several different toxins and
pollutants in various combinations.
Example: Aerosol sprays to kill pest like
mosquito and cockroach.

4. Noise & Light Pollution
These two kinds of pollution, noise and light
pollution, can cause severe destruction to
humans and the environment. These may further
progress in areas with sufficient natural spaces.
Light pollution is more alarming. However, in
urban areas where extreme noise is common,
noise pollution poses an immense danger.
Examples: High sounding noise of airplane
Too much use of led lights
https://th.bing.com/th/id/OIP.RQ5aMqD7AAKJKEbu
quIqhQHaFa?pid=Api&rs=1
3. Land & Soil Pollution
It is the accumulation of solid or liquid
matter on land or underground that can
pollute the soil and groundwater, place
public health at risk, and cause problems
and unsightly situations.
Example: Garbage thrown carelessly
anywhere
https://paintingvalley.com/sketches/pollution
-sketch-6.jpg
2. Water Pollution
It occurs when harmful element - often chemicals
or microorganisms—contaminate a stream, river,
lake, ocean, or other body of water, downgrading
the water quality and dispensing toxic to humans
or the environment.
Example: Chemicals coming from factories and
house wastes from residential areas.

Pollution affects living things in many ways:
 The decline in the reproduction of trees and crops can cause a scarcity of food and
oxygen for humans and animals.
 Reduction in the supply of safe and clean drinking water for humans and animals.
 Unpredictable weather patterns cause disturbances in the reproductive periods of
animals and plants.
 It causes respiratory diseases in humans, like asthma and lung cancer.
 Decreases the propagation of animals and plants in aquatic habitats.
 Decreases the supply of safe drinking water for humans and animals.
 It causes climate change and global warming that may affect living things
 Increase rapid climb in the population of disastrous insects that breed in a polluted
environment.
 Contaminates the habitat where organisms grow and develop.
 It alters the good timing for migration, mating, and blooming of living things.
 Hinders usual pattern or behaviors and eating cycles, causing a shrinking in wildlife
populations.

POLLUTION
There are so many problems in our
environment today it is because of the
hazard of pollution. It is the pollutants in the
air, water, and soil by different materials that
interfere with human health and quality of
life.
The emissions from big factories and
cars, contribute to air pollution and even
simple things that we do at home, like the
use of pesticides or scent sprays. These
have consequences in the ozone layer that
protects living things from ultraviolet
radiation.
Water is also in distress from
pollution by domestic and commercial
wastes.
It is all up to us to break the chain to
keep on damaging the environment. We all
should be environment friendly.
Answer the following questions.
1. What is the biggest enemy of the
environment?
