🌍 How Pollution Affects Human Health and the Environment
🧑⚕️ Effects on Human Health
Air Pollution
- Causes breathing problems (asthma, bronchitis)
- Increases risk of heart disease, stroke, and cancer
- Harmful gases (CO, NO₂, SO₂) and fine particles (PM2.5) are especially dangerous
Water Pollution
- Spreads diseases (cholera, typhoid, diarrhea)
- Contaminated drinking water affects kidneys, liver, and nervous system
- Heavy metals like lead and mercury can cause brain damage
Soil Pollution
- Toxins in soil can enter the food chain (through crops)
- Long-term exposure can cause health issues like cancer or birth defects
Noise & Light Pollution
- Leads to stress, sleep disorders, hearing loss (noise)
- Affects mental health and disrupts body rhythms (light)
🌿 Effects on the Environment
- Harm to Wildlife
- Toxic chemicals kill or harm animals and plants
- Oil spills and plastic waste damage marine life
- Ecosystem Disruption
- Pollutants alter habitats, food chains, and natural cycles
- Soil and Water Damage
- Reduces soil fertility and contaminates freshwater sources
- Climate Impact
- Air pollution (like CO₂ and methane) contributes to global warming
