Environment's Functions
The environment performs four vital functions: supplies resources, assimilates waste, sustains life by providing genetic and biodiversity, and provides aesthetic services.
Carrying Capacity
It refers to the ability of the environment to absorb resource extraction and waste generation without undergoing permanent degradation or collapse.
Opportunity Cost of Development
The massive industrial growth and resource exploitation have led to severe environmental damage, creating an opportunity cost in terms of health hazards and resource depletion.
Sustainable Development
Development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs.
Global Warming
A gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants.

Frequently Asked Questions
What is the difference between absorptive capacity and carrying capacity?
Carrying capacity is the maximum population or activity an environment can support without destruction, whereas absorptive capacity is the ability of the environment to absorb generated waste.
Why are non-conventional sources of energy important for sustainable development?
Non-conventional sources like solar and wind energy are renewable, cause negligible pollution, and reduce dependence on exhaustible fossil fuels, aligning perfectly with sustainable goals.
How does economic development cause environmental degradation?
Rapid industrialization, urbanization, and intensive agriculture lead to high resource consumption, deforestation, excessive waste generation, and pollution, straining the environment beyond its carrying capacity.
