It is an agenda that aims at fighting against environmental damage, poverty, disease through global co-operation on common interests, mutual needs and shared responsibilities. One major objective of the Agenda 21 is that every local government should have its own local Agenda 21 to combat environmental degradation.

Urbanization impacts business in many ways. It creates new markets, and consumers moving to urban areas typically have higher levels of income.

Why do business benefit from urbanization? Urbanization makes it possible for important infrastructure to come up and this means the cost of production and transportation goes down tremendously. Urbanization also makes it possible for a business to have more clients as the population of the urban center grows.

There were more employment opportunities in factories, at least initially, until there was overpopulation of people looking for jobs in cities. This influx of people into cities has caused the spread of cities and urbanization.

Sustainable development can be defined as an approach to the economic development of a country without compromising the quality of the environment for future generations. This damage may surpass the advantages of having more quality output of goods and services.

Agenda 21 is a non-binding action plan of the United Nations with regard to sustainable development. It is a product of the Earth Summit (UN Conference on Environment and Development) held in Rio de Janeiro, Brazil, in 1992.

Agenda 21 also recognises the interdependence of environmental, social, health and economic issues, emphasising that all people have the right to food, health care, shelter and education. Agenda 21 suggests new ways in which different groups can be involved in the decision making process.
