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.
