Environmental Problems, Issues,
and Concerns in the Community
Environmental problems in developed
and developing countries worldwide are
among the most important concerns
facing people and their governments.
These problems include population
pollution of water, air, and soils; waste
disposal; and loss of species.
Biodiversity in the Philippines is
unique. This means many of the life
form that are found in our country are
found nowhere else in the world. A key
to understanding this uniqueness is the
knowledge of the habitats ecosystems
where these plants and animals are
Agricultural is said to be the
“backbone” of our
country’s economy since the most Filipinos depend
on farming. Natural farming and tilling of the land
or soil is more recommendable than using high
yielding varieties because it can preserve the
environmental ecosystem. Using chemicals and
fertilizers threatens the soils’ ability to recycle
nutrients and good materials for plants. Killing the
healthy soil, they also burden the farmers because of
CORAL REEF SYSTEM
has some of the richest and
most diverse coral reefs in the world. If left
disturbed, the animal populations of the reef
will increase in number. The reef ’s provides
recreation and tourism opportunities due its
magnificent beauty. Taking good care of the
coral reef ecosystem is essential.
Water is life. All living creatures depend on it.
Clean water means clean ecosystem as a whole.
Once a body of water is polluted, the living things
within will die and those which or who depend on
them will also be affected. Human beings will also
suffer because of their life depends on water;
drinking, bathing, washing clothes and other
healthy forest ecosystem is “productive”.
Productivity means efficient use of the natural
resources or materials available in the system
without external inputs ad without leaving behind
any harmful effects . The importance of ecosystem

Major Types of Air Pollution
a. Outdoor Pollution is a type of pollution
derived from the mixture or collection of
additional loads of chemicals produced
atmosphere, thereby, producing harmful
effects to living.
Sources of Outdoor Pollution
• Burning of fossil fuel for power
• Photochemical and industrial smog
• Volcanic eruptions
• Forest fire
b. Indoor Air Pollution a type of
accumulation or build up of
chemicals inside the office, building,
houses, school, commercial store
and are harmful to health.

discharges pollutants into bodies of
water to specific location.
Non-Point source – a source of pollution
that are widely scattered and discharges
pollutants over a large sea.
b. Water pollution-causes

• Biodegradable waste, compostable and
can be reused as feeds, fermentable,

• Non-biodegradable waste, they factory

1. Reduce, avoid wasteful consumption
2. Reuse, items that are useful instead of
throwing them away
portions of these waste are sorted out
and used for something of benefit.
4. Repair, reusable items to make them
functional rather than throwing them.
