RESOURCES AND ENVIRONMENT
RESOURCES
• Are materials that are used to
help satisfy human needs.
• It includes natural resources,
human resources, and physical
resources.
RENEWABLE NATURAL
RESOURCES• Are those that can be replaced
within a certain period, such as
forests, soils, plants, and
animals, and water.
FOREST
It was a large areas of land
covered by trees, which
grown naturally for centuries
and include shrubs, mosses,
wild flowers and other small
plants.
ECONOMIC VALUES:
It supplies wood from trees.
Including timber and plywood
which are used in making houses,
furniture, and fuel for heating and
cooking, paper, plastics and fibers.
It provides rubber, oils, latex,
and various other materials.
It provides forest plants and
animals which are used for food
and medicines.
CLASSIFICATIONS OF FOREST
BOREAL FOREST- have
one layer of 20-meter trees.
These forest are usually found
if Northern Asia, Europe and
America.
TEMPERATE DECIDUOUS
FOREST- consists mainly of
broadleaf deciduous trees with
shrub and herb layers growing on
fertile soil. These forest are
usually found in Europe and in
parts of East Asia.
TEMPERATURE EVERGREEN
FORESTS- consist of needle leaf,
redwood, and eucalyptus trees , as
well as liverworts and ferns. These
are usually found in North and South
America, as well as pacific, where
they are home to native flora and
fauna.
MEDITERRANEAN FOREST-
consist mainly of evergreen oaks
and laurels and thrive in moist
winter and hot summers. Aside
from Mediterranean these types
of forest are also found in Africa
and Australia.
TROPICAL RAINFOREST- have
a wide array of trees, but mostly
broadleaf evergreens , with
shrubs, herbs and climbing
plants. Most tropical forest are
found in almost all parts of the
world.
TROPICAL SEASONAL
FOREST- also consist of variety of
trees, most are deciduous trees,
including bamboos and palms.
These forest are commonly found
in almost all parts of the world.
SAVANNAS- are found where
trees are widely spaced, and
where most of the grounds are
covered shrubs, herbs, and
grasses, which is why they are
mistaken for grasslands. These
are mainly found in Africa.
MOUNTAIN FOREST- consist
of deciduous, needle leaf, and
pines. Deer, bears, and panda
live in this kind of ecosystem,
which found in the mountains
of Europe and Asia.
DEFORESTATION
It is the destruction of forests for
human needs without corresponding
replacement of lost trees. These leads
to soil erosion, drought, flooding, loss
of wildlife, as well as worsening
greenhouse effect, as fewer trees can
absorb carbon dioxide from the air.
SOIL
Another renewable resource,
and is very important
because it is where most
living things get their food
sources.
ECONOMIC VALUES
Source of food for plants and
animals
Serves as grazing land and
shelter for herds.
PLANTS
Very important economic resource,
and in fact, it is the crucial to life
itself.
Come in a variety of forms and
shapes, in different types, and
hundreds of thousands of species
have been identified, and possibly
even more.
ECONOMIC VALUES
They provide food, as human eat
the plants as themselves, or their
fruits and parts.
They serves as raw material for
building houses, rope-making and
for clothing.
They serve as medicine when
their parts are processed for
purposes of providing healing
concoctions or drugs.
ANIMALS
Considered also as valuable
resources and are so diverse
that no one knows exactly how
many years they are.
There are thousands of kinds
of fish, birds, reptiles,
amphibians, and mammals.
ECONOMIC VALUES
They provide food to people.
They give them clothing.
They help people in their
work.
NONRENEWABLE RESOURCES
These resources that cannot be
replaced anymore.
There is a need to use them
efficiently. Because it takes a very
long time for this minerals to form.
They are being used faster than
they can form.
COAL
A kind of rock that can be burned
to produce heat and energy. Coal
comes from the remains of plants
that died millions of years ago, and
formed thick layers of matter
which eventually developed into
rocks. This is why it is called fossil
fuel.
It is used to produce
electricity from coal-burning
power plants.
To produce coke for the
manufacture of steel.
PETROLEUM
Currently the leading energy
resource in the world, and almost all
machineries, equipment, and
vehicles are powered by petroleum
products.
It also provides electricity and
power to households and businesses.
It is more generally known as
oil, and is sometimes called black
gold for wealth it has brought for
its producers.
Beneath the earth’s surface.
Heavily concentrated in Middle
East( Saudi Arabia and Kuwait).
RECYCLABLE RESOURCESALUMINUM
This a light metal that can be
performed and reformed into any
shape possible.
Usually used for beverage and food
cans, foil wrappers, and various
containers; and also for cars,
airplanes, boats, ships, and different
vehicles.
COPPER
A reddish-orange metal that has been
used since ancient times. It is a
conductor of electricity, and is malleable
enough to be patterned into shapes.
Mostly used in the form of copper
wires, for conducting electricity ,
appliances, television sets, and
computers.
GOLD
One of the earliest known metals,
and has been a symbol of wealth for
people. This metal is beautiful to
look at, and is also malleable,
ductile, and resistant to rust. Used
for production of jewelry and for
various ornamental purposes.
