Ecological Footprint Calculator — सूत्र
## How to Calculate Your Ecological Footprint
The ecological footprint measures how much biologically productive land and sea is needed to support your lifestyle.
### Formula
**Total gha = Carbon gha + Food gha + Housing gha + Goods gha**
**Earths Needed = Your Footprint / Earth's Biocapacity per Person**
### Benchmarks
- World average: 2.7 gha
- US average: 8.1 gha
- Earth's biocapacity: ~1.6 gha per person
- If everyone lived like Americans, we would need 5 Earths

हल किया गया उदाहरण
An American with 12 tons CO2, moderate food, 2,000 sq ft home, $1,000/month spending.
- Carbon: 12 * 0.34 = 4.08 gha
- Food: 1.2 * 0.9 = 1.08 gha
- Housing: 2,000 * 0.0003 = 0.60 gha
- Goods: 1,000 * 12 * 0.00005 = 0.60 gha
- Total: 4.08 + 1.08 + 0.60 + 0.60 = 6.36 gha
- Earths needed: 6.36 / 1.6 = 4.0 planets
