War is often regarded by observers as honorable and noble. Mary Walker won the Medal of Honor during the Civil War. While fewer women are "natural killers," and women are on average smaller than men, there are many women who have the psychological makeup and the physical ability to fight. Fifteen percent (204,000) of American military personnel are female.Ĭan women fight as effectively as men do? This is thought to be a reflection of culture and biology. Worldwide, 97 percent of today's military personnel are male.
In America, sources of aggressive dispositions include domestic violence, the portrayal of violence in the media, threats from enemies, and combat training.
However, aggression is a product of biology and environment. There is no single "war gene." Combinations of genes can predispose a person to violence. These included conflicts in Afghanistan, Algeria, Burundi, China, Colombia, the Congo, India, Indonesia, Israel, Iraq, Liberia, Nigeria, Pakistan, Peru, the Philippines, Russia, Somalia, Sudan, and Uganda. How many wars are taking place right now?Īt the beginning of 2003 there were 30 wars going on around the world. Of the world's 20 largest militaries, 14 are in developing nations? India has 1.3 million, North Korea 1 million, and Russia 900,000. China has the world's largest, with 2.4 million.
The combined armed forces of the world have 21.3 million people.
How many people around the world serve in the military? The reduced birthrate during World War II is estimated to have caused a population deficit of more than 20 million people. War has several other effects on population, including decreasing the birthrate by taking men away from their wives. Estimates for the total number killed in wars throughout all of human history range from 150 million to 1 billion. Of the past 3,400 years, humans have been entirely at peace for 268 of them, or just 8 percent of recorded history.Īt least 108 million people were killed in wars in the twentieth century. War is defined as an active conflict that has claimed more than 1,000 lives.
