Define the following term:
Pesticides

Define the following term:
Sanitary landfills

Definition: Soil Pollution
The contamination of soil by natural or synthetic substances that adversely affect its physical, chemical, and biological properties and reduce its productivity is called soil pollution.
Key Points
Key Points: Greenhouse Effect and Global Warming
- Greenhouse gases like CO₂ and methane trap heat in the atmosphere, preventing its escape and causing the greenhouse effect.
- Increased burning of fuels and deforestation raise CO₂ levels, intensifying global warming.
- Global warming results in rising temperatures, melting polar ice, higher sea levels, and reduced agricultural and fishery yields.
