Industrialisation is mainly of two types :
A. Such materials should be produced which are at present imported from abroad e.g. production of superior quality of cloth.
B. Such materials should be manufactured for which raw materials may be imported from abroad, and utilising cheap labour of this country, those items may be produced and exported abroad, e.g. garments and ceramic industries. Cloths being imported from outside and by utilising cheaper local labour garments are produce and exported. It is a profitable business.
Unplanned growth of industries deteriorates the environments in many ways. Mills and factories should not be established in human habitation. Because.
1. Industrial smoke pollutes the air of the locality.
2. If unused and excess raw materials and by-products are, not removed properly, these may often decompose and pollute both soil and air.
3. Often in the name of by-products the industrial wastes are thrown to the river or other water reservoirs. As a result the water of the reservoir become polluted and may cause harm to fishes and other aquatic animals living there. Use of this polluted water may also do harm to human beings. So industries should not be established here and there in unplanned way.
4. If industries, producing high sounds are established in human localities, people of those areas will become victim of soun pollution. In this way unplanned industrialisation directly or indirectly may affects the environment. Unplanned industrialisation deteriorates the public hygiene of environment. so before establishing any industry in an area the above factors should carefully be taken into consideration.
