A resource is something which can be used to make something else.
It may be a natural material like soil, water, a gas or mineral. Or it maybe a special skill.
Skills such as those doctors, farmers or teachers are resources.
Resources are used within a country inmanufacture, trade, jobs andservices.

Natural Resources
Natural resources are the raw materials produced by nature. The Earth isfull of these resources.
Some are foundunderground: water, and minerals like iron ore, coal, gold,silver and oil.
Many of these resources supply fuel for heat light and power. Somenatural resources are found under the sea: marine fish and shellfish andminerals like oil andaragonite (a Bahamian resource excavated from thesea floor at Ocean Cay and then used in the manufacture of glass andfertilizers).

The industries involved with the collection of naturalresources are calledprimary industries mining, fishingand farming.
Most natural resources need some sort of change orprocessing before they can be used.

Human Resources
The special skills and knowledge of people arehuman resources. A doctoruses skills that she or he has learnt to cure you when you are ill. Yourteacher uses skills in the classroom. A dressmaker uses skills to make
clothes.
Human resources are needed to make good use of natural resources.

Renewable Resources
Some of the Earths resources arerenewable.
This means that they can be used over and over again. For example, when trees arecut down, new trees can be planted on the same ground to replace those that havebeen removed.
Climatic resources are also renewable. Water, a natural resource, evaporates from the Earths surface to form clouds. The water is returned to the Earth again as rain or snow. This process is called thewater cycle. Renewable resources should not run out, if they are used wisely. The rainforests
described in Chapter 12 are renewable resources. Do you think they are being usedwisely?

Non Renewable Resources
Some resources cannot be replaced once they have been used. These are non renewable.
Minerals like oil and coal are non-renewable resources.
They are essential to the needs of modern society.
New sources of these minerals are constantly being sought, but one daythey will run out. The consequences of the world could be disastrous.

Importance of Resources to Economic Development
Today people use many different resources to meet their needs.
These resources are important to our survival in a changing
world. They provide:The materials to build their homes
The fuel to heat and light their homes
The food we eat

The clothes we wear
We need special skills to produce and develop these resources. Resources also make our environment beautiful to live in and
pleasant to look at. It is important to look after, orconserve, ourresources.
If we use too much of them, or waste them, there will be noneleft for future generations.

The gathering and processing of resources helps our country develop. In the Bahamas, people are employed in the primary industries of farming
and fishing.
But our main industry is tourism, which supplies most of our income. The natural resources of The Bahamas beautiful scenery, clear seas and
plenty sunshine are vital to this industry. Tourists come to our islands to enjoy activities like scuba diving, game
fishing, snorkeling, swimming and sunbathing. All these depend upon the conservation of our natural resources.

Conserving Resources and Recycling
How much of our resources will be left for future generations depends upon how weuse our resources now.
Many of the worlds resources are being used up too fast. Countries that have many different manufacturing industries are using large amounts
of the worlds minerals. These are used to make a vast range of products, from airplanes and bombs to cars
and toys. Huge quantities of coal, oil and natural gas are used, to provide energy for the
factories and fuel for transport.

Some say: We should not make products from natural resources unless
they can be recycled. This means using the product again in some way. If oil is turned into
plastic, it can never be changed back it can never become part of theEarth again.
But it can be recycled. For example, recycled plastic can be used to make plastic containers, fiber
insulation or polyester fabric.
Motor oil can be recycled and used as fuel for ships and industrial boilers.

Saving water in your bathroom When you BRUSH YOUR TEETH just wet your brush, then turn off the
water.
Only turn it on again when you need to rinse out your mouth. Check your TOILET. Take the top off the toilet tank in your home. Put about
12 drops of red food colouring in the tank. Wait for about 15 minutes. Nowlook in the toilet. If there is coloured water in the bowl, there is a leak in thesystem.
Are you using too much water in your SHOWER? Heres how to find out. You will need: an empty milk carton; a watch with a second hand; someone totime you.

Open the top of the milk carton.
Turn on the water so that it is at a normal flow. Then get in ( not with your clothes on, of course!) and hold the milk carton up to the shower-head for 10 seconds. The person helping you with the stop-watch will tell
you when to start and when to stop.
If the carton overflows in less than 10 seconds, you are using too muchwater and you should reduce the rate flow.

Conserving Your Recycling: What Can You Do?
Use less water
Collect kitchen vegetable waste, and vegetation cut from the garden. It willenrich and improve the soil.
Collect aluminum, glass and paper. Take them all to the nearest recyclingcentre.
Keep plastic and paper bags. Use them again and again, to carry shoppingor collect rubbish.
