Population – The child on the Balkan Peninsula in October, 1999
Humans – Six Billion People with # to be 9.3 to 12 billion
in 50 years
Other Species – “r” Their intrinsic
capacity for increase (lemmings, rabbits v. elephants)

LINKING POPULATION TO GREEN AGRICULTURE AND TOXINS
Today we are to determine a “world population policy” that will deal with issues affecting life on the planet.
Humans
Other Species
The Environment
The United Nations (UN), an accepted
authority on population levels and trends, estimates that the world population
reached 6 billion in 1999, and is increasing annually by more than 77 million
persons. The rate of increase, 1.3 percent per year, has fallen below the peak
rate of 2 percent per year attained by 1970. By the late 2040s, the UN
estimates, the growth rate will have fallen to about 0.34 percent annually, at
which time more than 50 countries will experience negative growth.
And who are all of these
people? In the April 1997 issue of Women's Press the following
summation was made. If we divided the world's population by 60 million
there would be 100 humans, of whom:
·
57 are Asian
·
21 are Europeans
·
14 are Hispanics from the Western
Hemisphere
·
8 are Africans
·
51 are females
·
70 are non-white
·
70 are non-Christian; 30 are Christian
·
6 individuals control 50% of the
world's wealth--all Americans
·
70 are unable to read
·
50 suffer from malnutrition
·
1 is near death and 1 is about to be
born
·
and only 1 would has a college
education
