RESOURCE- INTRODUCTION

• ^{Anything that can be used to satisfy a need or has value can be called a resource. Water, electricity, rickshaw, vegetable and textbook all have utility and hence are considered as resources. All the resources have value or worth. Some resources have economic value, some do not.}

Types of Resources

• Natural Resources are drawn from nature and are used without much modification. Examples include the air we breathe, water in our rivers and lakes, soil, minerals and so on.

• Natural resources are further classified into two kinds .

• .Renewable resources can be renewed and get replenished very quickly.(Solar and wind energy )

• Non-renewable resources have limited stock and once exhausted may take thousands of years to be replenished.(coal , petroleum)

• Physical factors like terrain, climate and altitude affect the distribution of natural resources.

Human Made Resources:

• At times, natural substances become resources only after their original form has changed.

• People make use of natural resources to manufacture human made resources like buildings, bridges, roads, machinery and vehicles. Another example is technology.

Human Resource

• Human Resource refers to the number (quantity) and abilities (mental and physical) of the people.

• That is why human beings are a special resource.

• People are human resources. Improving the quality of people’s skills so that they are able to create more resources is known as human resource development.

Conserving Resources

•  Using resources carefully and giving them time to get renewed is called resource conservation

• Carefully utilising resources so that besides meeting the requirements of the present, it also takes care of future generations is called sustainable development.

WAYS TO CONSERVE

• There are ways to conserve resources. Each person can contribute by reducing consumption, recycling and reusing things.

  The future of our planet and people is dependent on our ability to maintain and preserve the life support system that nature provides. Therefore, we are required to ensure that:

• all uses of renewable resources are sustainable

• the diversity of life on the earth is conserved

• the damage to the natural environmental system is minimised

SUSTAINABLE DEVELOPMENT

Sustainable development means using resources wisely without damaging the environment and keeping in mind the need of future generations.

This can be achieved by making the right balance between using the resources to meet our present needs and conserving them for future.
