World and Population
Information about the World and the population growth
Globally, the 20th century was marked by: (a) two devastating world wars; (b) the Great Depression of the 1930s; (c) the end of vast colonial empires; (d) rapid advances in science and technology,
from the first airplane flight at Kitty Hawk, North Carolina (US) to the landing on the moon; (e) the Cold War between the Western alliance and the Warsaw Pact nations; (f) a sharp rise in
living standards in North America, Europe, and Japan; (g) increased concerns about the environment, including loss of forests, shortages of energy and water,
the decline in biological diversity, and air pollution; (h) the onset of the AIDS epidemic; and (i) the ultimate emergence of the US as the only world superpower.
The planet's population continues to explode: from 1 billion in 1820, to 2 billion in 1930, 3 billion in 1960, 4 billion in 1974, 5 billion in 1988, and 6 billion in 2000.
For the 21st century, the continued exponential growth in science and technology raises both hopes (e.g., advances in medicine) and fears
(e.g., development of even more lethal weapons of war).
