Trace your shirt’s journey from the cotton field to your wardrobe.
First of all, the farmer grows cotton crop in the fields through the process of sowing. The plant grows slowly and flowers emerge from the bud. By breaking these buds, a swollen substance is separated from them. The thread is separated from within the seeds through the process of spinning. This is done either by hand or using a loom. Nowadays modern machines are used in the form of looms. After weaving the cotton cloth, it is sent to wholesalers. It is sent from wholesalers to retailers. We buy this fabric from retailers and give it to the tailor for stitching. The shirt is ready to wear from the tailor. This is how a shirt travels from a cotton field to our wardrobe.

How to identify location to set up an industry:
Divide your class into groups. Each group has a board of directors charged with the problem of selecting a suitable site for an iron and steel plant on the developed island. A team of technical experts has submitted a report with notes and maps. The team considered access to iron ore, coal, water and limestone, as well as key markets, sources of labor and port facilities. The team has suggested two sites, X and Y. The board of directors has to take the final decision about where to set up the steel plant.
- Read the report submitted by the team.
- Study the map to know the distance of resources from each place.
- Give each resource a ‘weight’ from 1 to 10 according to its importance. The greater the ‘pull’ of the factor on the industry, the greater the weighting from 1 to 10.
- Complete the table on the next page.
- The site with the lowest total should be the most satisfactory site.
- Remember that each group of directors may make different decisions.
Factors/resources affecting the location of the proposed iron and steel
Plant trees on the developed island.
- Iron Ore: It has a huge deposit of low grade iron ore. Long distance transportation of ore would be uneconomical.
- Coal: The only coalfield has abundant reserves of high grade coal. Coal is transported by railways, which is relatively cheap.
- Limestone: It is widely available on the island, but the purest reserves are in the Lime Mountains.
- Water: Both tributaries of the Nile carry enough water to supply a large iron and steel plant in all seasons. Sea water is unsuitable due to its high salt content.
- Market: It is expected that the main market for the plant’s products will be the engineering works of Rajdhanipur. Transportation costs for the products—primarily small steel bars and mild steel plates—will be relatively low.
- Labor Supply: This will be recruited mainly from unskilled workers in the 3 fishing villages of Hill, Rah and Sing. It is expected that most workers will commute daily from their current homes.
- Port facilities: These are minimal at present. A good, deep natural harbor has been developed at Paschimpur Port for import of metal alloys.
