FOOTPRINT CALCULATION FOR
THE YEAR OF THE WHALE

FOOD
Everyone has a garden:
.5 + .5 + .5 + .5 +.5 = 2.5 FOOD
Everyone helped hunt, fish & gather food: 1.0 FOOD
Net across the lagoon used to harvest fish: 1.5 FOOD
Christine, Jeff and Meriah have
quarter-circle chicken farms: .25 + .25 + .25 = .75 FOOD
Horsemeat jerky: .25 FOOD
Whale meat: .5 FOOD
6.5 Food produced - 5.0 Food consumed = 1.5 Food Stored

WATER
Normal rainfall year
24.5 Forest circles produce about 8.0 WATER
About 8 Scrub circles produce about 1.25 WATER
9.75 Seagrass circles produce about .5 WATER
9.75 Water produced - 5.0 Water consumed - 1.0 Water for windmill = 3.75 Water extra
No water was stored

FUEL and CARBON DIOXIDE
21 Forest circles scavenged for 3.5 Wood FUEL units
Coal Seam mined for 1 Coal FUEL unit
Whale Blubber burned for .5 FUEL unit (.5 stored)
Pressure chamber consumes .25 Oil FUEL unit
Ivy's power source invention consumes .25 Coal FUEL unit
5.5 Fuel units consumed = 5.5 Carbon Dioxide units ("Carbons") produced

24.5 Forest circles absorb about 4 CARBONS
8 Scrub circles absorb about .67 CARBON
9.75 Seagrass circles absorb about .25 CARBON
About 3.5 Garden and Field circles absorb
about .08 CARBON
4 + .67 + .25 + .08 = 5 Carbons absorbed
5.5 Carbons produced - 5 absorbed = .5 net increase in greenhouse gases

Bottom line:
Plenty of food - extra stored
Enough water
Everyone kept warm in the winter
Very small effect on the weather (warming)
Footprint size (total) - about 7.75 circles
Footprint size (individual) - 1.55 circle
