They are the first step towards the creation of the goods and services that we use every day. Industries, including including agriculture, fishing, and mining are directly involved in the extraction of raw materials from nature.

In simple words, primary industries are the ones use the natural resources of the environment and provide the raw material for secondary industries. 

Think of farming. It is responsible for the production of food items that are further processed by secondary industries to create a wide range of products. 

Types of Primary Industries

The two types of primary industries are extractive and genetic.

Extractive Industries 

These involve the extraction of natural resources. Examples include mining, fishing, forestry, and agriculture.

Genetic Industries

These are involved in the reproduction and breeding of plants and animals. Examples of genetic industries include agriculture and animal husbandry. 

Both these types of primary industries play a crucial role in providing the raw materials needed for the manufacturing of goods and the provision of services in other sectors.

Why is Primary Industry Important? 

They are the backbone of any economy as they provide employment to a significant part of the population and contribute towards the economic growth of a country. A booming primary industry sector has a direct correlation with the overall growth of the economy. 

Their importance cannot be underrated as it is responsible for the livelihood of many people, especially those who live in rural areas. It also provides the raw material required for secondary industries to function and, thus, plays a crucial role in the overall development of the country.

Automobile manufacturing, textile manufacturing, and oil refining are some major examples that are involved in processing raw materials. Workers in this industry are referred to as blue-collar workers. 

Two Types of Secondary Industry

Light Industry

Light industry creates products that are relatively small, easy to use, and often found in our daily lives. These products can include things like clothing, smartphones, and kitchen appliances.

This subcategory usually doesn’t require massive machines or extensive raw materials. It’s the kind of industry that makes things we use at home or wear, like clothes and household items.

Heavy Industry

Heavy industry, on the other hand, deals with making heavy and large products. These products are often used by other industries to build even bigger things. Examples include steel, heavy machinery, and chemicals.

Unlike the light industry, this one needs significant machines and a lot of resources because it deals with making large and intricate items. It plays a crucial role in creating the foundation for other industries to work with.

Importance of Secondary Industry
