Can anyone correct one paragraph for me (negative effects of technology)?

Although they started with primative weapons, human beings have developed even more advanced methods to kill one another. Technology has dominated warfare since the early 1900s, and billions of people have been killed since then. One such technological advancement was the bomb. Bombs can kill all species, including: women, children, and animals. The area around the land hit by the bomb keeps the radiation in it’s soil for a long time. An example of this is Japan, where the effects of the atoimic bombs of World War Two are still being felt to this day. Today guided weapons, like "smart" bombs, along with space-based sensors and precision satellite navigation, provide decisive advantages in conventional warfare. In this high-spending game, less capable opponents are soon reduced to guerrilla tactics, and the human cost of war remains high. Computerized aircrafts are currently being sent to kill innocents; saving the attackers the bother of dirtying their hands from the job.
