What we have learnt
- Pesticides, while useful for agriculture, have led to soil and water contamination and can adversely affect human health.
- Marine pollution poses serious threats to marine life and ecosystems, primarily due to oil spills and chemical discharges.
- Noise pollution affects human health and well-being, causing irritability and potential long-term hearing loss.
Key Concepts
- -- DDT
- A pesticide that caused significant environmental harm, leading to bans in many countries due to its persistence and bioaccumulation in the food chain.
- -- Marine Pollution
- Pollution of ocean waters due to human activities, including waste disposal and oil spills, which harm aquatic life and ecosystems.
- -- Noise Pollution
- Unwanted or harmful sound that can lead to health issues such as hearing loss, stress, and sleep disturbances.
- -- Thermal Pollution
- Addition of excess heat to water bodies from industrial sources, leading to detrimental effects on aquatic life.
- -- Nuclear Hazards
- Environmental threats stemming from radioactive waste, which can cause serious health issues and long-term ecological damage.
