Secondary sector
This sector generally takes the output of the primary sector and manufactures finished goods. These products are then either exported or sold to domestic consumers and to places where they are suitable for use by other businesses. This sector is often divided into light industry and heavy industry. Many of these industries consume large amounts of energy and require factories and machinery to convert the raw materials into goods and products. They also produce waste materials and waste heat that may pose environmental problems or cause pollution, the reasons that this sector is declining is because , of the increasing cost of labour, and the increasing safety standards, also there is an increase in technology, meaning you can use 1 man with a machine to do the same amount as 20 people. Plus in other countries the little labour that you need are much cheaper, some example of these countries are, China, India and Japan. Another reason is the increase of laziness in people, because some people would rather work in an office from 9 am to 5pm, than work in a field from 6am till 7pm.
Tertiary
The tertiary sector of industry involves the provision of services to other businesses as well as final consumers. Services may involve the transport, distribution and sale of goods from producer to a consumer, as may happen in wholesaling and retailing, or may involve the provision of a service, such as in pest control or entertainment. The goods may be transformed in the process of providing the service, as happens in the restaurant industry. However, the focus is on people interacting with people and serving the customer rather than transforming physical goods. In the past the primary sector had its growth and now it has its decline after the Industrial Revolution the Secondary sector had its growth....now declines. Now the tertiary sector has its growth reason because with raising incomes, consumers spend a larger and larger proportion of their incomes nowadays on services such as health, education and financial services.

Primary
The primary sector of the economy is the sector of an economy making direct use of natural resources. This includes agriculture, forestry, fishing, mining, and extraction of oil and gas. There is an overall decline in the primary sector in the UK due to coal and raw materials reducing in number. It has seen a significant growth in the organic industry since the advertisement of organic food they are also declining because the UK imports primary sector goods from other countries because it is cheaper.
Local and national examples
Primary sector – Mining
Tertiary sector – Harrods
Secondary sector – McDonald’s

Mining
Mining is the extraction of raw materials from the earth. It is all about obtaining material that cannot be reproduced through agricultural processes, or created artificially at a laboratory or factory.
Mining is practiced all around the world and different materials are obtained from different countries. Some of the materials recovered by mining include metals, coal and oil shale, gemstones, limestone, dimension stones, rock salt and potash, gravel and clay.
Unfortunately, mining has been decreasing since technology has improved and started to take over the jobs that people used to have. Two of the main reasons why this has happened are because of the health issues that they involve and how much this job has affected people throughout the years of hard labour. The second reason is that the mining equipment that each individual needs to perform the tasks is very expensive. For this reason, this has caused a great increase in the use of technology and improvement of machinery.
