Reduce, Recycle, Reuse, Refuse
- Reduce, Recycle, Reuse, and Refuse are known as the "4 R's" for sustainable development.
Crude Birth Rate
- The crude birth rate is the number of live births per 1000 people in a population annually.
Biological Oxygen Demand (BOD)
- The BOD is the amount of oxygen required for microbial degradation of organic matter in water.
Fossil Fuels
- Remains of organisms converted into fuels are fossil fuels.
Tremors
- The shaking and trembling of Earth is called a tremor.

Protection of Wild Species
- Laws prohibit the hunting and capture of wild species.
Chipko Andolan
- The Chipko Movement, involving women in Tehri-Garhwal, Uttarakhand, was a significant environmental movement.
Landfills
- Landfills are areas outside cities where municipal waste is dumped.

- The Montreal Protocol, put forth by the United Nations Environment Programme (UNEP), is a treaty aimed at phasing out ozone-depleting substances.
Biosphere
- The biosphere encompasses all living organisms and their interactions with the environment.
Ecosystems
- Ecosystems are smaller units within the larger biosphere, representing specific environmental systems.
Greenhouse Effect
- The greenhouse effect is a natural process that warms Earth's surface.
Global Warming
- The greenhouse effect is responsible for global warming, which is the abnormal warming of Earth's climate.
Greenhouse Gases
- Carbon dioxide (CO2) and water vapor (H2O) are major greenhouse gases.
Desert Climate and Temperature Fluctuations
- In deserts, the lack of water vapor in the air leads to significant temperature differences between day and night due to the absence of a barrier for emanating infrared radiation from the Earth's surface.
