3. Urban services

The bigger the town or city, the more services are usually found. As more people live in cities, more services are needed. For any business to be profitable, there has to be a minimum number of persons to support such a business. A pharmacy depends on at least 2 000 customers to survive. Certain services, however, are available in all cities, for example post offices, while other services are only available in some cities, for instance universities.

Urban services fall in different categories, such as:

a) Public services such as libraries, magistrate’s offices, hospitals, police stations, schools and churches.

b) Financial and professional services, such as medical practitioners, dentists, veterinary surgeons, attorneys, banks and insurance companies.

Commercial enterprises such as pharmacies, jewellers, furnishers, outfitters and bakeries, as well as butchers and car dealers.

4. Urban problems

Cities experience a variety of problems due to factors such as a rapid increase of residents, that put a strain on resources. The following problems are generally found in most cities:

a) Traffic problems due to the large number of residents who are road users.

b) Pollution due to gases emitted by factories and cars.

  1. Strain on agricultural land bordering on the outskirts of the city due to the demand

for land development.

d) Deterioration of buildings in the CBD due to age and a lack of maintenance.

5. The impact of human activities on the environment

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
