🏭 Human Impact on Atmospheric Composition
- Burning fossil fuels increases CO₂ levels — releasing carbon that was locked away for millions of years
- Deforestation reduces photosynthesis capacity — less CO₂ removed from atmosphere
- Industrial processes release CO₂, CH₄, and other greenhouse gases
Consequence: Contributing to the enhanced greenhouse effect and climate change.
