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. In the name of economic development, the price of environmental damage is paid in the form of land degradation, soil erosion, air & water pollution, deforestation, etc. This damage may surpass the advantages of having more quality output of goods and service.
Sustainable Development Aim is:
- To promote the kind of development that minimizes environmental problems.
- To meet the needs of the existing generation without compromising the quality of the environment for future generations
Features of Sustainable Development

What is Environmental Crisis?
- Environmental crisis refers to a situation when an environment fails to perform its vital function of life sustenance.
- The environment is suitable as soon as 1. Resource extraction remains below the rate of resource generation.2. Generation of waste remains within the absorption capacity of the environment.
Reasons for the Environmental Crisis:
(1) Population Explosion
- The high rate of growth of population adversely affects the environment.
- It increases the demand for environmental resources but their supply is limited.
- This results in overuse and misuse of resources.
(2) Rise in Economic Activity
- Rise in economic growth results in affluent consumption and production of goods and services.
- It generates waste which is beyond the absorptive capacity of the environment.
(3) Rapid Industrialization
- Rapid industrialization has led to deforestation, depletion of natural resources.
- It leads to water contamination due to the increasing volume of toxic substances and industrial wastes into the water bodies.
- A large migration of population from rural to urban areas results in the fast growth of slum areas.
- It leads to the excess burden on the existing infrastructural activities.
- Deforestation refers to cutting down of trees, clearing forest, etc.
- It adversely affects the environment and causes other problems.
(6) Increased Use of Insecticides, Pesticides and Chemical Fertilisers
- Farmers and workers suffer health problems due to increased use of poisonous insecticides, pesticides, and chemical fertilizers.
- The crop generated also contains chemical elements in it.
