1.1 Rate of birth : 19 per 1000 population per year
Rate of death: 9.3 per 1000 population per year
Rate of immigration: 2.7 per 1000 population per year
Rate of emigration: 11.5 per 1000 population per year
Overall population change rate:
R = [Rb -Rd] + [Ri – Re]
= [0.019 – 0.0093] + [0.0027 – 0.0115] = 0.0009
Or 0.9 per 1000 population per year.

1.2 1990 population = 3.72 million
Rate of population change from 1990 to 2005 = 0.9 per 1000 population per year Population in 2020 = P0 e Rt =3 720 000 x e 0.9/1000 x 30 = 3,821,808.

1.3 Emissions per equivalent US dollar of GDP for each country in 2007:

Country| Population| GDP| Co2 emissions| GDP/capita| E CO2/GDP| Brazil| 188| 621| 106| 3303.1915| 170.6924316|
China| 1314| 2512| 1665| 1911.7199| 662.8184713|
India| 1095| 796| 338| 726.94064| 424.6231156|
Nigeria| 132| 83| 114| 628.78788| 1373.493976|
United States| 298| 1322| 1709| 4436.2416| 1292.738275|

1.4
To be able to calculate the equivalent CO2 , the rate population of change is calculated: P= P0 e Rt
R= (1/t) ln (P/P0)
R = 0.0126341
CO2 for 2010 calculation =
eCO2= Population x GNP(%/yr)/person x CO2 /GNP(%/yr)

| Population| GNP growth(%/yr)| decrease in eCO2/GNP (%/yr)| eCO2| | 2000| 2010| 2025| 1990-2000| 2000-2025| | 2007| 2010| 2025| Brazil| 175| 199| 240| 3.6| 2.8| 0.5| 170.6924| 278.6| 336| China| 1290| 1489| 1600| 5.5| 4| 1| 662.8185| 5956| 6400| India| 990| 1262| 1425| 4.7| 3.7| 0.2| 424.6231| 933.88| 1054.5| Nigeria| 148| 210| 250| 3.2| 2.4| 0.1| 1373.494| 50.4| 60| United States| 270| 294| 307| 2.4| 1.7| 0.7| 1292.738| 349.86| 365.33| 2.1I agree that 25 - 50 years as the best choice for a sustainability planning timescale. As those timescales are roughly to be two humans generations. So the plan can still be evaluated and...
